Ice Mining is the process of mining ice field (commonly called "ice belts"). This mined ice can then be refined into fuel for Player Owned Structures (POS) and Capital Ship Jump Drives. 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

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 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.
• Standard asteroids (Glare Crust, Dark Glitter, Gelidus, and Krystallos) contain large quantities of Heavy Water, Liquid Ozone and Strontium Clathrates, but no faction isotopes.

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

					Faction isotopes
		Heavy Water	Liquid Ozone	Strontium Clathrates	Helium Isotopes	Nitrogen Isotopes	Oxygen Isotopes	Hydrogen Isotopes
Faction	Clear Icicle	50	25	1	300
	White Glaze	50	25	1		300
	Blue Ice	50	25	1			300
	Glacial Mass	50	25	1				300
Enriched	Enriched Clear Icicle	75	40	1	350
	Pristine White Glaze	75	40	1		350
	Thick Blue Ice	75	40	1			350
	Smooth Glacial Mass	75	40	1				350
Standard	Glare Crust	1000	500	25
	Dark Glitter	500	1000	50
	Gelidus	250	500	75
	Krystallos	125	500	125

	Heavy Water	Helium Isotopes	Hydrogen Isotopes	Liquid Ozone	Nitrogen Isotopes	Oxygen Isotopes	Strontium Clathrates
Blue Ice
Clear Icicle
Glacial Mass
White Glaze
Thick Blue Ice
Enriched Clear Icicle
Smooth Glacial Mass
Pristine White Glaze
Dark Glitter
Gelidus
Glare Crust
Krystallos

There are 4 basic types of ice asteroid. These match the faction that controls local space. With perfect ice refine capability, 1 unit of each type will always produce:

• 50 Heavy Water
• 25 Liquid Ozone
• 1 Strontium Clathrates
• 300 of a faction-specific isotope, as follows:

	Amarr - Clear Icicle	Caldari - White Glaze	Gallente - Blue Ice	Minmatar - Glacial Mass
Isotope	Helium	Nitrogen	Oxygen	Hydrogen
