'''Ice Mining''' is the process of mining ice field (commonly called "ice belts"). This mined ice can then [[refining|refined]] and used to fuel capital ship [[jump drive]]s, manufacture fuel for [[POS|player-owned starbases (POS)]], and light [[cyno|cynosural fields]]. Ice mining can only be done with specialized modules (ice miners) which can only be fit to [[ORE Basic Ship and Skill Guide|Mining Barges and Exhumers]]. Unlike [[Mining|ore mining]], ice miners mine one block of ice (with a volume of 1000&nbsp;m<sup>3</sup>) per cycle; as it's not possible to increase this yield, the only way to mine ice more efficiently is to decrease the ice miners' cycle times.

Like asteroid ore, unrefined ice takes up a large amount of space and can therefore be time-consuming to transport. The best sub-capital ship for transporting ice (and ore) is the [[Miasmos]], a Gallente industrial which can transport up to 63,000&nbsp;<sup>3</sup> (63 blocks, or about twice the capacity of a [[Mackinaw]]) of ice. If you need to haul even larger quantities, it may be worth training to fly a [[freighter]] (which can hold over ten times as much), or to ship the ice by courier contract.

The core skill for ice mining is the (appropriately named) {{sk|Ice Harvesting|icon=yes}}, which reduces the cycle time of ice mining modules by 5% per level. Train this to level V to use the Tech 2 ice miner. {{sk|Mining Upgrades|icon=yes}} is needed to install mining upgrade modules (which further decrease the cycle time of ice miners).

=== Ice Mining ships ===

{{main|Mining Ships}}
 +
==== Mining Barges ====
 +
Of the three mining barges, only the [[Covetor]] has a bonus to ice mining (3% reduction in cycle time per level of {{sk|Mining Barge|icon=yes}}); at Mining Barge V it can mine about 15% more ice than its counterparts. However, its ore hold is fairly small (7000&nbsp;m<sup>3</sup>), and will fill up in about ten minutes. The [[Procurer]] and the [[Retriever]] have the same ice mining yield, and each ship has a different strength (the Retriever has a very large ore hold, and the Procurer a very tough tank). As when using these ships for ore mining, the choice depends on your play style. Flying in a dangerous region of space? Use a Procurer. Want to mine for long stretches without returning to a station? Use a Retriever. Want to get the absolute maximum amount of ice you can? Use a Covetor.
 +
 
 +
The other thing to note is that the Covetor, Retriever and Procurer can fit three, two, and one ice miners (respectively), but the Retriever and Procurer have an in-built bonus to cycle times (to arrive at similar overall yields, as above). Therefore, when mining with a Procurer you will have very short cycle times but can only mine one block of ice at a time, whereas a Covetor has much longer cycle times but can mine three blocks of ice at once.
 +
 
 +
==== Exhumers ====
 +
Exhumers are straight upgrades from their Mining Barge counterparts, and the same reflections hold true for them. One small difference is that both the Skiff and the Mackinaw get a small (1%) reduction to ice harvester cycle time per level of {{sk|Exhumers|icon=yes}} (the Hulk gets a 3% reduction per skill level, like its counterpart the Covetor).

In contrast with ore mining, all ice mining modules mine exactly one unit (1000&nbsp;m<sup>3</sup>) of ice per cycle; therefore, the only way to increase your mining efficiency is to decrease your modules' cycle time. This can be done by training skills (see above), installing more advanced [[ORE_Basic_Ship_and_Skill_Guide#Ice_miners|ice mining]] and [[ORE_Basic_Ship_and_Skill_Guide#Mining_laser_upgrades_and_ice_harvester_upgrades|mining upgrade modules]], fitting [[ORE_Basic_Ship_and_Skill_Guide#Ice_harvester_accelerator|Ice Harvester Accelerator]] rigs, or flying more advanced ships. Additionally, if you are in a fleet, you can receive further bonuses through [[Mining_Yield#Fleet_boosts|fleet boosts]].

As mining ice often turns into a race, with large number of miners competing to mine as much ice before the belt is emptied, having short cycle times can be an advantage beyond simply mining more ice in a given period of time. This allows you to beat your competition to those last few pieces of ice in a belt (as, if two miners are attempting to mine the same asteroid with only one unit of ice left, whoever finishes their cycle first gets that block of ice, and the other gets nothings). 
  
Improving cycle times important more than increasing yield, but winning race when clearing ice belts.
 
 
=== Ice Mining Ships ===
 
(Discuss some of the bonuses to ice mining of the various ships, as well as their cargo hold sizes)
 
 
 
===Retriever===
 
 
The following skills are the minimum skills required to pilot a Retriever.
 
 
* [[Skills:Science#Astrogeology|Astrogeology  III]]
 
* [[Skills:Science#Science|Science IV]]
 
* [[Skills:Production#Industry|Industry V]]
 
* [[Skills:Spaceship Command#Mining Barge|Mining Barge III]]
 
* [[Skills:Resource Processing#Mining|Mining IV]]
 
 
===Ice Harvester===
 
 
in addition, to harvest ice, the following skill is required.
 
* [[Skills:Resource Processing#Ice Harvesting|Ice Harvesting I]]
 
 
With these skills the miner can acquire 1 piece of ice, per Ice Harvester, every 300 seconds (5 minutes).
 
 
==Improving Cycle Times==
 
 
===Skills===
 
 
Further training in [[Skills:Resource Processing#Ice Harvesting|Ice Harvesting]] will decrease the cycle time by 5% per level to a maximum 25% reduction in cycle time. Minimum cycle is therefore 225 seconds.
 
 
===Tech 2 Modules===
 
With Ice Harvesting 5 it is possible to use the Ice Harvester II module. This has a base cycle time of 250 seconds reducing to 187.5 seconds with the skill bonus applied. Ship bonuses , depending on what barge/exhumer you are using, can also affect harvesting. (bonuses are noted further down)
 
 
===Ice Harvesting Upgrades===
 
 
(Using the Retriever as an example)
 
 
Cycle times can be reduced further using Ice Harvesting Upgrades. These work in the same way as Mining Laser Upgrades, but reduce the cycle time instead of increasing yield. A T1 upgrade provides a 5% bonus (10% CPU penalty) and a T2 upgrade provides a 9% bonus (12.5% penalty). To minimise cycle time the aim is to fill all low power slots with these modules for a combined cycle reduction of 27%.
 
[Note: Training up Skills:Industry#Mining Upgrades|Mining Upgrades will reduce the penalties as well as allowing use of the T2 upgrade at a higher level.]
 
 
Personal experience: I found that when fitting my ship with the Ice Harvester Upgrade IIs I ran out of CPU with 3 active and was unable to fit the two T2 Ice Harvesters. The issue was resolved by using a cpu upgrade rig (there were leftover calibration points) and training higher levels of  [[Skills:Electronics#Electronics|Electronics]].
 
 
<!-- todo: check if 9%->18%->27% upgrade stacking is correct, -->
 
<!--
 
===Rigs===
 
[https://wiki.eveonline.com/en/wiki/Medium_Ice_Harvester_Accelerator_I Medium Ice Harvester Accelerator I] results in a 12% reduction to the duration of ice harvester cycles. Calibration cost: 250
 
 
===Implants===

Provides for 1%, 3%, or 5% reduction in cycle time, respectively.
 
 
===Other Considerations===
 
 
'''Ice Output'''<br>
 
Due to the changes:
 
        Skiff 66% reduction in cycle time + 1% for every level of Exhumer
 
        Mackinaw  33% reduction in cycle time + 1% for every level of Exhumer
 
        Hulk 0% reduction in cycle time but + 4% for every level of Exhumer
 
      [NOTE: mining barges have the same ship bonuses minus the Exhumer bonus]
 
'''Cargo Space'''<br>
 
 
        The Mackinaw its the elite in cargo hold followed by the skiff leaving the
 
        Hulk trailing behind at last place.
 
 
'''Survivability''' <br>
 
While most ice mining is done in hisec, suicide gankers often see the AFK nature of ice miners as an advantage.
 
 
        The Skiff takes the far lead due to its bonuses in shield tank ability.
 
 
'''Price'''<br>
 
 
        Most dedicated miners will own a Hulk for high-yield mining, so frequently the
 
        Mackinaw is bought as a second ship dedicated to solo mining due to the large
 
        Ore hold.
 
        The market for both change depending on the demand or availablity, due to this
 
        reason the price cant be set as a guide to what ship is the cheapest and most
 
        cost effective.
 
        looking at you local market and comparing the price with your needs will
 
        have to be taken into account to see what is the best for you.
 
 
'''The big question – Is Ice mining actually for me?'''
 
 
Yet again another question without a correct answer.
 
There are many reasons for and against Ice Mining, but there are some important facts that need to be said.
 
Ice has a limited use compared to asteroids. Minerals from asteroids are used throughout eve, basically everything out there is made out of minerals where as ice products are only used in Player Owned Structures (POS) and certain ships with jump drive capability.
 
 
The final big issue is well, that ice is big! Just one block takes up 1000m3 of space. So an unmodified Hulk can only fit a low amount, not much really. Many professional ice miners will have a second account to act as a hauler to move the ice and leave the miner in place, be in a fleet or use the ore hold god called the Mackinaw.
 
 
==Perfect Ice Mining Requirements==
 
 
Mackinaw skills:
 
* [[Skills:Spaceship Command#Exhumers|Exhumers V]]
 
* [[Skills:Spaceship Command#Spaceship Command|Spaceship Command IV]] 
 
* [[Skills:Production#Industry|Industry V]]

Ice Mining Upgrades
 
 
This skill set will result in a reduction of cycle time on your lasers.
 
 
Modules, such as the Ice Harvester Upgrade can further decrease the cycle time.
 
Implants, such as the 'Yeti' series can even further decrease this time.
 
If possible, use a fleet booster such as an Orca, with boosts to decrease cycle time. Remember the yield boosters are useless, so the only boosts you can do in relation to Ice mining are time decreases.

Revision as of 12:00, 25 April 2014

Ice Mining is the process of mining ice field (commonly called "ice belts"). This mined ice can then refined and used to fuel capital ship jump drives, manufacture fuel for player-owned starbases (POS), and light cynosural fields. Ice mining can only be done with specialized modules (ice miners) which can only be fit to Mining Barges and Exhumers. Unlike ore mining, ice miners mine one block of ice (with a volume of 1000 m3) per cycle; as it's not possible to increase this yield, the only way to mine ice more efficiently is to decrease the ice miners' cycle times.

Note: the Odyssey expansion (June 2013) changed ice mining considerably. Before the expansion, ice belts were permanent features in a system, with thousands of ice asteroids spread over hundreds of kilometers. This was changed to much smaller (10-20 ice asteroids each with 50-200 units of ice) dynamic belts which disappear once mined out, and then respawn four hours later.

Advantages of Ice Mining

  • Reduced attention required by the miner when compared with ore mining.
  • Ability to be self-sufficient for POS fuel.
  • Easier to mine without a dedicated hauler (longer cycle times mean fewer trips to the station).
  • Fun factor of 4-hourly 'Ice Rush' when a belt spawns, as dozens of miners rush in to clear the belt.

Disadvantages of Ice Mining

  • Reduced ISK yield compared to ore mining. While ice commands similar prices to ore, it's not possible to mine ice continuously due to the 4 hour respawn timer on ice belts.

Ice Belts

A map of the Metropolis region from dotlan. The Eygfe system has an ice belt, as shown by the thin blue ring around its box.

Ice belts can be found in every region of New Eden, but only in certain systems (a good place to see which systems is dotlan). Each of these systems contains one ice belt, which spawns after downtime, disappears once mined out, and then respawns four hours later. Unlike asteroid belts, ice belts are a type of Cosmic Anomaly, meaning they will appear in a different location in the star system every time they respawn, and can be found using your ship's onboard scanner (but do not require scan probes to find).

Ice Asteroids

There are twelve different types of ice asteroids, split into three categories: faction asteroids, enriched faction asteroids, and standard asteroids.

  • Faction asteroids (Clear Icicle, Glacial Mass, Blue Ice, and White Glaze) refine to small quantities of Heavy Water, Liquid Ozone and Strontium Clathrates, but large amounts of their respective faction's isotope (Helium Isotopes, Hydrogen Isotopes, Oxygen Isotopes, and Nitrogen Isotopes). Each of these asteroid types is only found in the regions of space controlled by their respective faction (so, for instance, Blue Ice only spawns in Gallente space, and contains Oxygen Isotopes, which are used to fuel the jump drives on Gallente ships and to manufacture fuel for Gallente POSes).
  • Enriched faction asteroids (Enriched Clear Icicle, Smooth Glacial Mass, Thick Blue Ice, and Pristine White Glaze) work the same way as regular faction asteroids, but contain more of the same materials. These asteroids are only found in nullsec (in systems controlled by their respective factions).
  • Standard asteroids (Glare Crust, Dark Glitter, Gelidus, and Krystallos) contain large quantities of Heavy Water, Liquid Ozone and Strontium Clathrates, but no faction isotopes. These asteroids are only found in low-sec and nullsec.

Assuming perfect refining skills, ice asteroids refine to the following:

Like asteroid ore, unrefined ice takes up a large amount of space and can therefore be time-consuming to transport. The best sub-capital ship for transporting ice (and ore) is the Miasmos, a Gallente industrial which can transport up to 63,000 3 (63 blocks, or about twice the capacity of a Mackinaw) of ice. If you need to haul even larger quantities, it may be worth training to fly a freighter (which can hold over ten times as much), or to ship the ice by courier contract.

Ice Mining Mechanics

Main article: Mining

Ice mining works in much the same way as ore mining: equip a ship with ice mining modules, approach and target an ice asteroid, and activate the mining module. At the end of each cycle, one unit of ice will be deposited in your ship's cargo or ore (yes, it holds ice too) hold. However (unlike ore mining) ice mining modules and only be fit on Mining Barges and Exhumers, and mining drones cannot be used.

Skills

Main article: Mining skills

The core skill for ice mining is the (appropriately named) Icon skillbook2.png Ice Harvesting, which reduces the cycle time of ice mining modules by 5% per level. Train this to level V to use the Tech 2 ice miner. Icon skillbook2.png Mining Upgrades is needed to install mining upgrade modules (which further decrease the cycle time of ice miners). Lastly, the Icon skillbook2.png Mining Barge and/or Icon skillbook2.png Exhumers skills are needed to fly ice mining ships; training higher levels of these skills also decreases the cycle time of ice mining modules (depending on the bonuses of the ship being flown). Since most mining modules are fairly CPU-intensive (and fitting ice mining upgrades only makes this worse), you will probably need to train some fitting skills to take full advantage of your ice mining ship.

Ice Mining ships

Main article: Mining Ships

Mining Barges

Of the three mining barges, only the Covetor has a bonus to ice mining (3% reduction in cycle time per level of Icon skillbook2.png Mining Barge); at Mining Barge V it can mine about 15% more ice than its counterparts. However, its ore hold is fairly small (7000 m3), and will fill up in about ten minutes. The Procurer and the Retriever have the same ice mining yield, and each ship has a different strength (the Retriever has a very large ore hold, and the Procurer a very tough tank). As when using these ships for ore mining, the choice depends on your play style. Flying in a dangerous region of space? Use a Procurer. Want to mine for long stretches without returning to a station? Use a Retriever. Want to get the absolute maximum amount of ice you can? Use a Covetor.

The other thing to note is that the Covetor, Retriever and Procurer can fit three, two, and one ice miners (respectively), but the Retriever and Procurer have an in-built bonus to cycle times (to arrive at similar overall yields, as above). Therefore, when mining with a Procurer you will have very short cycle times but can only mine one block of ice at a time, whereas a Covetor has much longer cycle times but can mine three blocks of ice at once.

Exhumers

Exhumers are straight upgrades from their Mining Barge counterparts, and the same reflections hold true for them. One small difference is that both the Skiff and the Mackinaw get a small (1%) reduction to ice harvester cycle time per level of Icon skillbook2.png Exhumers (the Hulk gets a 3% reduction per skill level, like its counterpart the Covetor).

Improving yield

Main article: Mining Yield

In contrast with ore mining, all ice mining modules mine exactly one unit (1000 m3) of ice per cycle; therefore, the only way to increase your mining efficiency is to decrease your modules' cycle time. This can be done by training skills (see above), installing more advanced ice mining and mining upgrade modules, fitting Ice Harvester Accelerator rigs, flying more advanced ships (Exhumers instead of Mining Barges), or using implants (the IH-100x Inherent Implants 'Yeti' Ice Harvesting series). Additionally, if you are in a fleet, you can receive further bonuses through fleet boosts.

While each bonus may seem small, when taken together they can make a significant difference:

A beginning ice miner with very basic skills (Mining Barge I and Ice Harvesting I) fits her Covetor with three Ice Harvester I modules and goes looking for ice. Once she finds a suitable ice field, each of her three miners can mine a block of ice every 4 minutes and 36 seconds.

If she then spends some time training her Mining Barge and Ice Harvesting skills to level IV, she will have lowered her cycle time to 3 minutes and 31 seconds, an improvement of over 20%. Wanting to improve her yield further, she installs two Ice Harvest Upgrade modules on her Covetor (with some training to Mining Upgrades IV), which drops her cycle time to 3 minutes and 11 seconds.

She then upgrades her ship to a Hulk (with some training to Exhumers IV), and installs an Ice Harvester Accelerator rig for good measure, which brings her cycle time down to 2 minutes 40 seconds. Going for broke, she upgrades all her modules to their Tech 2 variants and trains her skills to level V, dropping her cycle time down to 1 minute 49 seconds, for a total reduction of 60%.

As mining ice often turns into a race, with large number of miners competing to mine as much ice before the belt is emptied, having short cycle times can be an advantage beyond simply mining more ice in a given period of time. This allows you to beat your competition to those last few pieces of ice in a belt (as, if two miners are attempting to mine the same asteroid with only one unit of ice left, whoever finishes their cycle first gets that block of ice, and the other gets nothings).
