The principal copper ore mineral is chalcopyrite (CuFeS 2), which is commonly smelted to yield a matte containing ~50% copper.In the presence of silica flux, iron is selectively oxidized to a slag. Figure 14 shows a PSD for the Cu–Fe–S–O system at 1 atm SO 2 as a function of temperature (Rosenqvist, 1978).Unlike the system for lead, the copper and …

In copper dump leaching, run-of-mine ore is irrigated with acidic leaching solution to generate aqueous cupric ions for further processing. The very large size of the ore particles being leached, as much as two meters in diameter, should preclude any significant metal recovery. Dump leaching should not work; and yet it does.
