Oxide Copper Leach Modeling

Oxide Copper Leach Modeling

+

The modeling of the leaching of copper oxide ores has not received as much attention as sulfide heap leaching. The acid leaching of copper oxide ores generates a vertical acid concentration gradient in the ore heap, which is not generally observed in sulfide deposits.

The lower concentration limit of this method, below which no visible copper sulfide would form, are not yet known. The rates of reaction between the copper rod and atmospheric hydrogen sulfide also are not known, nor are the influence of humidity or rain, or the relative rate of copper oxide formation. Thus, there are many questions yet to answer!
