I cant find find the full formula that affects what minerals you get and i would like to know so i can incorporate it into a web based project i am working on.

i need to factor in reprocessing, reprocessing efficiency, Ore/ice/scrap skill, Implant, quantity

as well as where should a number be rounded if at all.

I tried to work it out myself but i just cant get it to return the same numbers as ingame.

Station Equipment x (1 + Refining skill x 0.03) x (1 + Refining Efficiency skill x 0.02) x (1 + Ore Processing skill x 0.02) )

Add implant as needed.

Edit: this is for ores.

that is what i used before and i used the implant at the end but it did not return the right sum

Station Equipment x (1 + Refining skill x 0.03) x (1 + Refining Efficiency skill x 0.02) x (1 + Ore Processing skill x 0.02) x (1+implant x 0.01)) = Refine Rate

is what i used to get refine rate then

round down(Ore mineral yield x (Refine Rate/100) x quantity)

to get the amount of each mineral in each ore

also where does tax get removed?
so:
Base Station = 50
Reprocessing = 5
Reprocessing Efficiency = 5
Veldspar Reprocessing = 4
Implant = 2

Quantity = 100 (compressed)
mineral yield = 415

ingame (68.3% 28915 trit)

50 x (1 + 5 x 0.03) x (1 + 5 x 0.02) x (1 + 4 x 0.02) x (1+ 4 x 0.01)) = (50 x 1.15 x 1.1 x 1.08 x 1.02) = 69.9762
415 x (0.699762) * 100 = 29040.123

clearly i am doing something wrong and i have not even factored in tax yet there is no tax in the station i am working on.

You have an error in your formula. You have a 2% implant, but are calculating it as a 4%.

50 x (1 + 5 x 0.03) x (1 + 5 x 0.02) x (1 + 4 x 0.02) x (1+ 4 x 0.01)) = (50 x 1.15 x 1.1 x 1.08 x 1.02) = 69.9762

should read

50 x (1 + 5 x 0.03) x (1 + 5 x 0.02) x (1 + 4 x 0.02) x (1+ 2 x 0.01)) = (50 x 1.15 x 1.1 x 1.08 x 1.02) = 69.6762

roundDown(415 * 100 * .696762) = 28915 trit

Do you have >6.7 standings?

The UI doesn't show bonus from implants.

Tax Percent = MAXIMUM (0 ; 5 - Current Standing * 0.75)
