The Complete Miner's Guide by Halada9
Mineral is refined from the ore you mine. There are 8 kinds of mineral, 3 high-end types and 5 low-ends. Low-ends include Tritanium, Pyerite, Mexallon, Isogen and Nocxium. High-ends minerals include Zydrine, Megacyte and Morphite. High-ends minerals can of course only be refined from high-end ores, which can only be found in 0.0 (some in low-sec, refer to grid in section 1.1), which explains why their price is much higher than low- ends.
Here is a table that shows which ore gives which kind of minerals:
How should you interpret that table ?
Let's start with the batch. Quite simple, the batch is the number of units you will need for every refine. The numbers you see in every mineral's column is the quantity of minerals you will get per batch with a perfect refine. Let's use an example to make it clearer.
Let's use Omber as an example. Omber has a batch of 500. Say you mined 3467 units, and you hauled it back to a station which has a refinery. For every 500 units, if you have a perfect refining yield of 100% (yes, it is possible), you will get 307 units of Tritanium, 123 units of Pyerite and 307 units of Isogen. If you divide 3467 by 500, you will end up having 6 batches, and 467 units of Omber leftover.
This is a simple analogy, as you might have to pay taxes (paid in units of mineral during a refine) depending of your standing with the corporation owning the station and your skills. The refining system will be covered later in another section, however this table is very useful to know which asteroid you should mine depending of the minerals you need.
1.2.1 What Should I Mine Then?
Since the value of minerals fluctuate daily following the supply and demand law (if you don't know what that is, try googling it or listening in class ), it would be pointless to say "this mineral is always in high-demand, so mine that!". Eve-central has an excellent market report on minerals, with statistics up to the last 180 days. If you want to enter the mineral trading business (which is, I warn you, a very hard hobby) or simply be efficient, you should familiarize yourself with this great website ! No matter what you mine, there will ALWAYS be demand for it. Since the introduction of capital ships in the Red Moon Rising expansion, mineral consumption significantly raised, therefore don't worry, you won't be stuck with overstock, ever!
