Making a Profit
The hard part is making a profit as some items are sold very close to the cost of the minerals. You'll end up with a 0.1% profit margin, if you're lucky. However, because there are so many items in EVE, not everyone has optimized their sell/buy orders and you can use EVE-Cost Reprocessing Calculator to figure out at which point you can profit.
i got into [reprocessing] early when i still had only like 20mill ISK to my name. I turned it into 300m ISK fairly quick by massbuying armor and hull repairers all over Essence region, breaking them down and selling the minerals.
You get 5% taxes on all refining at 0.00 standings, which is reduced to 0% tax when your standings with the corporation reach (or exceed) 6.67. The connections skill also affects this.
Skills You Need
- Refining, 2% per level reduction in refinery waste, 10% total reduction
- Refinery Efficiency, 4% per level reduction in refinery waste, 20% total reduection
- Scrapmetal Processing, 5% per level reduction in refinery waste, 25% total reduction
The last skill is very important because it affects reprocessing for modules, ships and other reprocessable equipment. It also has some secondary skills you need to train: Metallurgy (level 5) and Science (level 4) which will take a longer time.
