You need Refining V, Advanced Refinery IV and Ore-specific Processing I to get a 100% refine
Do NOT start playing solo, first of all the cool effect will wear RuneScape Gold off WAY too fast and you will end up an old maid brushing the toilets of some battleships in deep space. The ISK is in the team work (at least at first) and I cannot stress this enough. Join a crop!
So what is up now Luke? I am in a crop, now what? Most corps does what we call inning ops and where a group of campmate mine together for a few hours and each get an equal share.
Sometimes the crop gets an extra share or a little more, for resale, production or trading. This is the best way to start, plus teamwork is always fun! If your crop does not buy you ore directly, then you have two options:
1. Refine the ore in minerals (trot, pyrite, mex, and sell it
2. Sell the ore unrefined
Problem with option 1 is that as a newbie your refining skills suck. You need Refining V, Advanced Refinery IV and Ore-specific Processing I to get a 100% refine.
HOWEVER, unless you have a 6.7+ standing with the NPC Corporation owning the station you refine at, you will pay taxes. Solution? Get a campmate to refine for you!
