It was the largest heap leaching plant in China to recover copper by the copper hydrometallurgy (L-SX-EW) at that time. In China, the output of metals extracted by the heap leaching method has increased year by year, and the great progress has been made in the ore types, heap construction, and liquid distribution of heap leaching, as …

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

The process was originally conceived as a heap leach operation followed by direct electrowinning of copper, with solvent extraction (SX) and electrowinning (EW) of cobalt. In preparing the sized ore for the heap leach operations, the undersized ore fraction at a P 80 of 625 um was discharged to a fines storage facility for later processing.
