An integrated process to recover copper from low-grade copper grade sulfide ore and acid wastewater (AMD) has been developed and applied. The process includes the operations of milling-flotation, heap bioleaching, SX-EW and copper sulfide precipitation. In the process, copper and valuable metals are efficiently recovered.
The Process. The concentrated ore is heated strongly with silicon dioxide (silica) and air or oxygen in a furnace or series of furnaces. The copper(II) ions in the chalcopyrite are reduced to copper(I) sulfide (which is reduced further to copper metal in the final stage).
Figure 1 shows a typical flow-sheet of hydrometallurgical copper processing, which consists of three fundamental unit operations: • leaching of copper ore with a week acidic solution, which ...
