Processed ore is more valuable than unprocessed ore but however if your mining skill is high and you are unable to process the ore you would not necessarily make a higher profit. You will also need to have your own facility to process it as well. The processing is far more feasible to group miners than soloing.

You should always plan out how you will plan on mining. Check for pirate threats, choose an asteriod and you must do it quick and efficient. You will need to appear Eve Isk  and disappear in the mining regions before the pirates have enough time to catch you. Bookmark your asteroid so when you jump back you should be 15km away from where you are heading to. This will save you a lot of time during each run.

You should maximize the time to money ratio. You are full high tail back to the station. You should check the market price before posting your ore for sale. At least you would know the going price. If you manage to mine a lot of more, a half decent offer of Eve Isk should be good enough, considering that you are able to mine quickly.
