Oxidation kinetics of a lime-copper concentrate pellet ...

Copper flotation concentrates can be oxidized while simultaneously fixing 98 pct of the sulfur as CaSO 4 and copper sulfates if a mixed lime-concentrate balled pellet is roasted at low temperatures. The roasting pellet exhibits a reacted shell surrounding the unreacted core. The rate is controlled by oxygen diffusion in the pores of the roasted shell and kinetic details are given.
