'''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). Lastly, the {{sk|Mining Barge|icon=yes}} and/or {{sk|Exhumers|icon=yes}} 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 [[Mining#Fitting_skills|fitting skills]] to take full advantage of your ice mining ship.
 
=== 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]].

Additionally, if you are in a fleet, you can receive further bonuses through [[Mining_Yield#Fleet_boosts|fleet boosts]].  


While each bonus may seem small, when taken together they can make a significant difference.
While each bonus may seem small, when taken together they can make a significant difference:
{{example|A beginning ice miner with very basic skills ({{sk|Mining Barge|I}} and {{sk|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.

She then upgrades her ship to a [[Hulk]] (with some training to {{sk|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). 


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===
[https://wiki.eveonline.com/en/wiki/Inherent_Implants_'Yeti'_Ice_Harvesting_IH-1001 Inherent Implants 'Yeti' Ice Harvesting IH-1001];
[https://wiki.eveonline.com/en/wiki/Inherent_Implants_'Yeti'_Ice_Harvesting_IH-1003 Inherent Implants 'Yeti' Ice Harvesting IH-1003];
[https://wiki.eveonline.com/en/wiki/Inherent_Implants_'Yeti'_Ice_Harvesting_IH-1005 Inherent Implants 'Yeti' Ice Harvesting IH-1005]
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]]
* [[Skills:Science#Astrogeology|Astrogeology V]]
* [[Skills:Science#Science|Science IV]]
* [[Skills:Resource Processing#Mining|Mining IV]]
* [[Skills:Spaceship Command#Mining Barge|Mining Barge V]] 
Ice Harvester II module:
* [[Skills:Resource Processing#Ice Harvesting|Ice Harvesting 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.
== MAX Pilot & MAX Fleet == (need to update post Odyssey - base cycle times halved)
(This results in a cycle time of 101 seconds for 2 blocks.)
'''Best Pilot''' (This results in a cycle time of 150 seconds for 2 blocks.)
* Ship: [[Mackinaw]]
** Above Skills
** Implant: Slot 10 - Yeti 5 (The Yeti 5 only improves cycle time by 5 seconds from the MAX of 101 to 106; so likely not worth the price.)
** High Slot: 2 Ice Harvester II (The ORE does not help reduce cycle time, only CPU; so likely not worth the price.)
** Low Slot: 3 Ice Harvester Upgrade II (The Ingenii does not help reduce cycle time, only CPU; so likely not worth the price.)
** Rig Slot: 1 Medium Ice Harvester Accelerator I (There is no II at the moment.)
'''Best Booster''' (This results in a 32.3% reduction in Activation Time.)
* Ship: [[Orca]]
