Heap leaching: energy economics?

This data-file captures the energy economics of leaching in the mining industry, especially the costs of heap leaching, for the extraction of copper, nickel, gold, silver, other precious metals, uranium, and Rare Earths. The data-file allows you to stress test costs in $/ton of ore, $/ton of metal, capex, opex, chemicals costs, energy intensity and…

Copper: the economics?

The economic cost of copper production is build up from first princples in this model, from mine, to concentrator, to smelter to 99.99% pure copper cathodes. Our base case is $7.5/kg copper cathode, with 4 tons/ton CO2 intensity, after starting from an 0.57% ore grade. Numbers vary sharply and can be stress-tested in the data-file.
