Extraction of Copper at Elevated Feed Concentrations

compared with a heap leach operation, to attain the extraction desired. An SX-EW operation is an acid plant. It takes copper out of solution and replaces it with protons which make their way, via the organic extractant, back to the raffinate stream. In heap leach operations the acid is consumed during leaching. In a concentrate leach scenario,

Copper Heap Leaching SX-EW Slideshow

A leaching solution of weak sulphuric acid is sprayed over the rock on the pad and allowed to percolate through to the base. As the solution passes through the heap, the copper-bearing mineral dissolves into solution. The copper-bearing solution accumulates in the collection pond and is piped to a nearby SX-EW plant for metal recovery. Leaching

Heap Leaching - an overview ScienceDirect Topics

2.1 Leaching. Most copper leaching is done by piling broken ore (∼0.5% Cu) into flat-surface, 3–10m high, 10 4 –10 5 m 2 heaps of ore and then sprinkling dilute sulfuric acid lixiviant on to the heap surface. The lixiviant trickles down through the heap and leaches copper from its minerals to produce a pregnant leach solution containing 1–5kg Cum −3.
