Line 37:

If you're using [[Drones#Mining Drones|mining drones]], launch your drones once you are near the asteroid, and give them the command to "mine repeatedly". They will then fly to the asteroid you have targeted, mine for one cycle (60 seconds), fly back to your ship, deposit the ore they have mined in your cargo or mining hold, then automatically fly back to the asteroid and continue mining it (until, as above, either your cargo/mining hold is full, or the asteroid has depleted because it no longer contains any ore). Since the drones have to fly back and forth repeatedly between your ship and the asteroid, it's worth flying as close as possible to the asteroid to keep their travel time down to a minimum.

Once your cargo or mining hold is full, bring the ore you have mined to a station (either fly there yourself, or transfer the ore to another player's ship to fly back (see [[Mining#Solo mining|solo mining]] and [[Mining#Cooperative mining|cooperative mining]] for more details)), then return to the asteroids and continue mining!

When deciding what ore to mine, the driving factor is income per volume of ore (ISK per m3). For example, Veldspar is the [[Asteroids and Ore#Asteroid distribution|most common and cheapest ore]] in EVE and has a volume of 0.1 m3 per unit; Scordite is the next most common ore but has a volume of 0.15 m3 per unit. Therefore (ignoring [[ORE Basic Ship and Skill Guide#Mining crystals|mining crystals]]), you will always mine 50% more Veldspar than Scordite in a given period of time (since mining lasers mine a fixed ''volume'' of ore per minute). Therefore, in order for Scordite mining to be more profitable than Veldspar mining, Scordite's market price must in turn be 50% greater than Veldspar's. Since the market is player-driven, ore and mineral prices are ever-changing, hence miners should always check the market for the most efficient ore/mineral to mine for.

Websites like [http://eve.grismar.net/ore/ Grismar's Ore Chart] can look up the current market prices for ores and minerals, and give you a recommendation which ores are the most profitable. Remember to double-check the prices that any automated tools give you - they will often use regional averages to determine mineral prices; if you plan to sell your goods at a specific station or hub then your priorities might come out differently. Lastly, don't forget that most ore types are only found in a [[Asteroids and Ore#Asteroid distribution|certain part of New Eden]], and most miners prefer to operate only in certain parts of space.

Once you have chosen what kind of ore you would like to mine, you will want to maximize the quantity you mine over time. This involves choosing what [[Mining Ships|ship]] to mine in, what [[ORE Basic Ship and Skill Overview#Fitting strategies and mining modules|modules]] to fit to it, and what [[Mining#Skills|skills]] to train; see those links for more details.

Moon mining can take place only at [[Upwell structures#Refineries|refineries]] anchored within 250 km of a mining beacon in 0.5 space or below and fitted with a Standup Moon Drill I service module, which appears on the outside of the structure as a giant laser turret aimed at the moon.

The Moon Drill is then used to extract a chunk of the moon for mining.

The extraction process is beyond the scope of this article, but once the chunk has been extracted, it exists as an asteroid field ~~which~~ contains both normal ore types and special moon-specific ores which can be mined for moon materials.

After a week's training, a budding miner should have the necessary skills to fly a mining barge, which have more than double the mining yield of a Venture, as well as even larger mining holds and/or a stronger tank. These ships are also more expensive (15-40M ISK, plus modules), but given that a Venture can mine about 500-700k ISK worth of ore per full mining hold, this money is soon earned. There are three different mining barges, each with a different focus (see table below).

The last word in mining ships are the [[exhumer]]s (Tech II variants of the mining barges). These ships require many more skills to fly, and are even more expensive, but have even greater mining yield, mining hold space and/or [[tank]] than the mining barges. Additionally, miners can train into the [[Prospect]] and the [[Endurance]], improved ~~and~~ variants of the Venture which are designed for covert mining in dangerous areas of space and ice mining, respectively.

The survey scanner (a mid-slot module) is a very useful tool for any asteroid miner, as it shows how much ore each asteroid in the vicinity contains. This is important, as asteroid mining modules (mining lasers and strip miners) will always complete an entire cycle (60s for mining lasers, 180s for strip miners), irrespective of how much ore is actually left in the asteroid.

For instance, say you are mining an asteroid ~~which~~ contains 200 units of Veldspar (Veldspar has a volume of 0.1 m3 per unit, so this asteroid contains 20 m3 of Veldspar). Your Mining Laser I has a yield of (say) 100 m3/min, and a cycle time of 60 seconds. Even though there are only 20 m3 of Veldspar left in the asteroid, the module will complete its entire 60 second cycle before shutting off (with a message saying "the asteroid is depleted") - but those 60 seconds of mining only yielded 20 m3 of ore (instead 100 m3)! The problem becomes even worse when using strip miners, as they have a much higher yield and a cycle time three times as long - which can result in a lot of wasted time if you're mining asteroids that don't contain much ore.

Therefore, when mining, refresh the survey scanner window from time to time (it does not refresh automatically, you need to reactivate the survey scanner module) to check whether the asteroid(s) you are mining are close to depletion. If an asteroid is almost empty, you can "[[Mining Yield#Short cycling|short cycle]]" your mining laser (i.e. turn it off manually before it completes its full cycle, by clicking on it) to mine out the last dregs of ore before moving on to another asteroid. Note that each time you activate your mining laser it takes energy from your ship's [[capacitor]]; activate it too often and you might empty your capacitor and have to wait a moment for it to recharge.

Line 249:

Players can jettison items from their holds into space, which results in a cargo container (more commonly called a "[[jetcan]]" or just a "can") forming within 2,500 m of the ship. This jettisoned container has a volume capacity of 27,500 {{m3}}. Miners can take advantage of this capacity by transferring the ore in their mining hold into the jetcan. Typically a player will fill a jetcan with ore, and then (once the jetcan is full) swap to a ship with a larger mining/cargo hold (most often an [[hauler]]) and haul the ore to a nearby station.

If you're flying a mining ship with an mining hold that's considerably smaller than a jetcan (such as a [[Venture]] (5,000 {{m3}} mining hold) or a [[Covetor]] (9,000 {{m3}} mining hold)), this method can increase your efficiency, as you can spend more time mining and less time hauling.

However, jetcans only have a lifespan of 2 hours and they are not secure, meaning [[Can flipping|anyone can open and remove items from a jetcan]]. This is a common form of theft and griefing in the game, where a player will "flip" a jetcan either to steal the ore or to induce a fight without [[CONCORD]] intervention. While it's possible to combat this by using secure containers (which can be programmed with a password), the largest of these (the giant secure container, often called a GSC) can only hold 3,900 m3 of ore, which is less than the mining hold on even the smallest mining ship.

As nearly all mining ships have mining holds which are as large or larger than a jetcan (in addition to the time lost in changing ships and the risk of getting your ore stolen), using jetcans is probably not worth your time. They do, however, come in very handy if you're [[#Dual account mining|mining with two accounts]] or in a [[#Mining fleets|fleet]] (see below). Given their small size, using GSCs for mining is not worth it (although it was a commonly-used practice in the past, when mining ships had much smaller cargo holds).

A better alternative to GSCs are mobile tractor units. They have nearly as much capacity as a jetcan, are unable to be accessed by random people, and have a ~~decays~~ of 2 days. They also suck in and store any ore a miner might jetcan into a safer place. A mining barge can store 3 MTUs and deploy them for a temporary total of 8,1000m3 of extra space. This allows for a large amount of time to be saved from station mining, as a miner instead of having to dock up can just jetcan the ore to be stored for later.

=== Dual account mining ===

If you have two EVE accounts, you can [[multiboxing|multibox]] them (i.e. play them on one computer simultaneously). One of these can mine while the other ~~ones~~ flies a [[hauler]] to drop the mined ore at a nearby station. The miner transfers the mined ore into a jetcan or a GSC (see above) which is then picked up by the hauler. This way, the miner can mine non-stop, obtaining more ore. Eventually, the hauler character could train towards an [[Orca]] (to provide mining boosts to the miner, further increasing yield), while the miner character is free to train and fly ships like the [[Hulk]], which have very high mining yield but small mining holds.

Of the professions in EVE, mining and production are most impacted by the player’s efficiency. For miners, it’s all about mining. Time spent hauling, killing rats, moving cans or dealing with ore thieves, can flippers and other flavors of griefers is time not spent making little rocks out of big ‘roids. Anything that can be done to eliminate or minimize the impact of all of those other factors means more little rocks in the hold, which means a fatter wallet.

Anything that can be done to eliminate or minimize the impact of all of those other factors means more little rocks in the hold, which means a fatter wallet.

Properly designed and staffed co-operative [[Archive:Mining fleets|mining fleets]] allow miners to spend their time doing what they do best: mining. It also allows the miners to benefit from mining yield bonuses available only to members of a group. These bonuses can add an additional 10% or more to a miner’s yield. If the miners are mining, then someone has to haul the little rocks to the station. If the op is in [[System security#Low security|lower sec regions]], something other than drones may be needed to protect the miners from rats, not to mention thieves and assorted other scoundrels. Those protection activities will result in a second “mining” operation as the wrecks are looted and salvaged for the benefit of the op participants.

Our theoretical op has miners, haulers, damage dealers and salvagers; a fairly broad slice of the possible professions in EVE! Mining ops are generally more relaxed than combat fleet ops, co-operative mission running or complex clearing. Chat and/or [[Mumble]] deal with a wider variety of topics and separating the required tasks to specialists provides everyone time to participate in the conversations. Not only does this atmosphere provide a social element of connection with the other members, it lets the "teaching" move beyond mining to cover a myriad of subjects.

The next type of fleet is more structured. A standard mining fleet in [[System security#High security|high security space]] generally includes a mix of mining barges, exhumers, and haulers. The miners will work on a single belt constantly, and transfer the ore they mine into a jetcan. The haulers will ferry the resources from space to a station. This makes for increased proficiency as the mining lasers never need to stop, unless you need to switch belts. Fleet boosters are usually present here as well, and an [[Orca]] may be used instead of a jetcan. Mining fleets in low-sec will also include combat ships to protect the fleet against rats and hostile players.

There are five types of ~~compresser~~: ~~Asterolid~~ ore, Gas cloud, Ice, Moon ore, and Mercoxit. ~~Compresser are comes with~~ three sizes: Medium ~~Compresser~~ for Porpoise, Large ~~Compresser~~ for Orca, Captial ~~Compresser~~ for Rorqual.

To ~~active~~ the ~~compresser~~, the ship has to ~~active their~~ Industrial Core first.

A batch of batch compressed ore ~~to reprocess is 1, since they are created by a whole batch of 100 ores~~.

A batch of "batch compressed" ore when reprocessed has the same yield as uncompressed ore.

Batch compressed ore has various volumes depending on the type, unlike the current compression which is all 0.01 or 0.1 ratio. See the below for specific volume information.

Therefore (ignoring [[ORE Basic Ship and Skill Guide#Mining crystals|mining crystals]]), you will always mine 50% more Veldspar than Scordite in a given period of time (since mining lasers mine a fixed ''volume'' of ore per minute). Therefore, in order for Scordite mining to be more profitable than Veldspar mining, Scordite's market price must in turn be 50% greater than Veldspar's. Since the market is player-driven, ore and mineral prices are ever-changing, hence miners should always check the market for the most efficient ore/mineral to mine for.
-Websites like [http://eve.grismar.net/ore/ Grismar's Ore Chart] can look up the current market prices for ores and minerals, and give you a recommendation which ores are the most profitable. Remember to double-check the prices that any automated tools give you - they will often use regional averages to determine mineral prices; if you plan to sell your goods at a specific station or hub then your priorities might come out differently. Lastly, don't forget that most ore types are only found in a [[Asteroids and Ore#Asteroid distribution|certain part of New Eden]], and most miners prefer to operate only in certain parts of space.

 After a week's training, a budding miner should have the necessary skills to fly a mining barge, which have more than double the mining yield of a Venture, as well as even larger mining holds and/or a stronger tank. These ships are also more expensive (15-40M ISK, plus modules), but given that a Venture can mine about 500-700k ISK worth of ore per full mining hold, this money is soon earned. There are three different mining barges, each with a different focus (see table below).

 The survey scanner (a mid-slot module) is a very useful tool for any asteroid miner, as it shows how much ore each asteroid in the vicinity contains. This is important, as asteroid mining modules (mining lasers and strip miners) will always complete an entire cycle (60s for mining lasers, 180s for strip miners), irrespective of how much ore is actually left in the asteroid.
-For instance, say you are mining an asteroid which contains 200 units of Veldspar (Veldspar has a volume of 0.1&nbsp;m<sup>3</sup> per unit, so this asteroid contains 20&nbsp;m<sup>3</sup> of Veldspar). Your Mining Laser I has a yield of (say) 100&nbsp;m<sup>3</sup>/min, and a cycle time of 60 seconds. Even though there are only 20&nbsp;m<sup>3</sup> of Veldspar left in the asteroid, the module will complete its entire 60 second cycle before shutting off (with a message saying "the asteroid is depleted") - but those 60 seconds of mining only yielded 20&nbsp;m<sup>3</sup> of ore (instead 100&nbsp;m<sup>3</sup>)! The problem becomes even worse when using strip miners, as they have a much higher yield and a cycle time three times as long - which can result in a lot of wasted time if you're mining asteroids that don't contain much ore.

 Therefore, when mining, refresh the survey scanner window from time to time (it does not refresh automatically, you need to reactivate the survey scanner module) to check whether the asteroid(s) you are mining are close to depletion. If an asteroid is almost empty, you can "[[Mining Yield#Short cycling|short cycle]]" your mining laser (i.e. turn it off manually before it completes its full cycle, by clicking on it) to mine out the last dregs of ore before moving on to another asteroid. Note that each time you activate your mining laser it takes energy from your ship's [[capacitor]]; activate it too often and you might empty your capacitor and have to wait a moment for it to recharge.

 Players can jettison items from their holds into space, which results in a cargo container (more commonly called a "[[jetcan]]" or just a "can") forming within 2,500 m of the ship. This jettisoned container has a volume capacity of 27,500&nbsp;{{m3}}. Miners can take advantage of this capacity by transferring the ore in their mining hold into the jetcan. Typically a player will fill a jetcan with ore, and then (once the jetcan is full) swap to a ship with a larger mining/cargo hold (most often an [[hauler]]) and haul the ore to a nearby station.
-If you're flying a mining ship with an mining hold that's considerably smaller than a jetcan (such as a [[Venture]] (5,000&nbsp;{{m3}} mining hold) or a [[Covetor]] (9,000&nbsp;{{m3}} mining hold)), this method can increase your efficiency, as you can spend more time mining and less time hauling.

 However, jetcans only have a lifespan of 2 hours and they are not secure, meaning [[Can flipping|anyone can open and remove items from a jetcan]]. This is a common form of theft and griefing in the game, where a player will "flip" a jetcan either to steal the ore or to induce a fight without [[CONCORD]] intervention. While it's possible to combat this by using secure containers (which can be programmed with a password), the largest of these (the giant secure container, often called a GSC) can only hold 3,900&nbsp;m<sup>3</sup> of ore, which is less than the mining hold on even the smallest mining ship.
-As nearly all mining ships have mining holds which are as large or larger than a jetcan (in addition to the time lost in changing ships and the risk of getting your ore stolen), using jetcans is probably not worth your time. They do, however, come in very handy if you're [[#Dual account mining|mining with two accounts]] or in a [[#Mining fleets|fleet]] (see below). Given their small size, using GSCs for mining is not worth it (although it was a commonly-used practice in the past, when mining ships had much smaller cargo holds).
