Case Study: Copper solvent extraction fires

The first two commercial copper solvent extraction (CuSX) plants were small-scale plants built in Arizona in the late 1960s. The plants were built to treat heap leach and dump leach solutions, respectively, and to produce 5,500-6,500 short tons per annum (STPA) of cathode copper. They were followed soon after by a much.

Heap leaching - Wikipedia

The leach solution containing the dissolved minerals is then collected, treated in a process plant to recover the target mineral and in some cases precipitate other minerals, and then recycled to the heap after reagent levels are adjusted. Ultimate recovery of the target mineral can range from 30% of contained (run-of-mine.
