Ok, so I've read the refining guides and seen the Yield Calculations and all that but I'm a bit confused.

So the yield calculation goes like this:

[Station Equipment] + 0.375 x (1 + [Refining Skill] x 0.02) x (1+ [Refinery Efficiency Skill] x 0.04) x (1+ [Ore Processing Skill] x 0.05)

So for me the equation looks like this:

0.5 + 0.375 x (1 + 5 x 0.02) x (1+ 5 x 0.04) x (1+ 4 x 0.05) = 1.1386

Tax is 5 - ( 0.75 * [standing])

So for me that's

5 - ( 0.75 * 1.8 ) = 3.65

Now, how does this work in relation to the Ore I have?

For example, how do I workout how much Nocxium I would get from 69,930 units of Pyroxeres? Is the above equation even related?

Before I would divide the Pyroxeres by the batch then multiply by the Nocxium as a result. e.g.

69930 / 333 * 11

I'm trying to build a spreadsheet for calculating needs based on production runs. The equation above is useless without context and I can't find anything that gives me that context.

I can find online converters but these don't tell me how they get their calculations.

Anyone know how this works?

Thanks

The numbers don't match though.

If I use the example of the amount I had:

69930 / 333 * 11

The answer = 2310

However, the load I got from the refining is actually 2226.

I'm missing something in my calculation somewhere.

I did the same, using 999 or 1200 units of each ore type, writing down what they gave in minerals. Years ago. Then later when I got perfect refine (due to Caldari Navy corp standing, and better skillz) I did it again, noting down the new amounts.

The OP needs to notice that there are two things that detract from mineral yield: Waste, and the "we take" thing. The firts is due to refining skillz, and the base yield of the refinery (hint: You want a station with a 50% base yield refinery), while the second is a sort f "tax" charged by the station, based on your standing with the NPC corporation owning the station.

This calculation is based on your standing after the Connections skill has been taken into account (so buy Connections and train it to 4), and you need a final standing value of about 6.7 in order to reduce the "tax" to zero.

You don't need to max out your refining skillz to get perfect refine. Just train the ore-specific skillz so that you can use T2 mining crystals in your T2 strippers, and then train Refining Efficiency to reduce waste to 0%.
