The recovery of metals from sulfiderich ore bodies proceeds through a series of steps: from mining to crushing to mineral recovery, followed typically by smelting of the sulfide ores, and thence to metal refining; although the nature of the ore body dictates the processes used to extract metals from ore, each of these steps generates a waste stream.
