Forge Cost Calculator A Tale in the Desert
The Forge Cost Calculator is currently set up as if you were smelting with a compression furnace 500 ore at a time, getting a .03 yield. If you are using a different method figure out the yield by dividing the metal you get by the ore you use, then put that number in the "copper per 500" and the "iron per 500" section.

Mining Valuation Lesson: CutOff Grade Theory and Practice ...
At a gold price of US1000 per ounce the value of the gold in the block of ore is just under 96 (1000/31 X 3 or 1000 per ounce/ 31 grams (troy ounce) X 3 grams of gold) Simply put, if it were to cost more than 96 to mine, treat, and extract the gold from that tonne of ore, it would be uneconomic to mine.

Mineral Comminution and Separation Systems
To be more specific, let us take the example of a copper ore whose grade, or copper content, is only 1% by weight. Let us assume that the sole copper mineral species in this ore be chalcopyrite, which is one of the most popular copper minerals found in copper ores in our planet. The chemical formula of chalcopyrite is known to be CuFeS2.
