Copper Leaching Solvent Extraction And Electrowinning …
Several leaching methods exist, with heap leaching and in-situ leaching being prominent examples. Heap leaching: Crushed ore is piled into large heaps, and a lixiviant (a leaching solution, typically sulfuric acid) is sprayed onto the heap. The copper dissolves into the solution as it percolates through the ore. This is cost-effective for large ...
