Reprocessing
Reprocessing in EVE is a combination of refining and recycling. It is the process by which ore is refined into minerals, ice is refined into ice products, and manufactured goods (such as modules, ships, and rigs) are recycled for their previous materials (e.g. T1 module/ship => minerals, capital ship => capital ship components, rig => salvage). There exists a very small selection of items in EVE which may not be reprocessed.
Each item in the game has a base material composition. What an item is reprocessed into can be found if you look for it in the item database. To reprocess you must be in a station or outpost with a reprocessing plant, or a POS with a refining array.
You can select as few or as many items as you like to reprocess. Once you have selected the items, hit the 'reprocess' button. This will show you the exact amount of minerals you will receive from reprocessing. At this point you can choose to reprocess, or cancel to stop. Bear in mind that your skills, standings to the owner, and the base reprocessing ability of the station and refining array will effect the amount of minerals (or other materials) that you will receive.
Reprocessing is a vital activity to industrialists and miners alike. Miners use it to reprocess their raw ore before taking the minerals to the market for sale. Industrialists use this to buy modules cheaply, reprocess them, and sell the minerals for profit. This is a vital facet to New Eden.
The direct factors involved in reprocessing are the recycling constant (37.5%), the refinery station's reprocessing plant's base yield, your exact skilled standing with the refinery station, and your skills in Refining, Refinery Efficiency, and one of the special processing skill. Due to the direct standing factor, your skill in Connections, Criminal Connections, or Diplomacy may be indirect factors.
The special processing skills are:
- Ice Processing (all varieties of ice)
- Veldspar Processing (asteroid ore)
- Scordite Processing (asteroid ore)
- Pyroxeres Processing (asteroid ore)
- Plagioclase Processing (asteroid ore)
- Omber Processing (asteroid ore)
- Kernite Processing (asteroid ore)
- Jaspet Processing (asteroid ore)
- Hemorphite Processing (asteroid ore)
- Hedbergite Processing (asteroid ore)
- Gneiss Processing (asteroid ore)
- Dark Ochre Processing (asteroid ore)
- Spodumain Processing (asteroid ore)
- Crokite Processing (asteroid ore)
- Bistot Processing (asteroid ore)
- Arkonor Processing (asteroid ore)
- Mercoxit Processing (asteroid ore)
- Scrapmetal Processing (manufactured goods - basically everything else)
The reprocessing % return formulas are:
- refining_factor = 1+(refining_skill_level*0.02)
- efficiency_factor = 1+(refinery_efficiency_skill_level*0.04)
- specialization_factor = 1+(special_processing_skill_level*0.05)
- Net Yield = station_equipment_base_yield + recycling_constant * refining_factor * efficiency_factor * specialization_factor
All-In-One
- Net Yield = station_equipment_base_yield + 0.375 * (1+(refining_skill_level*0.02)) * (1+(refinery_efficiency_skill_level*0.04)) * (1+(special_processing_skill_level*0.05))
