摘要
A mechanism of a solid-phase interaction between metallic copper released from the copper-nickel alloy in nickel recovery into the carbonyl gas phase with nickel sulfide in carbonylation of copper-nickel metallurgical half-products is suggested. Experimental data on carbonylation of the magnetic fraction of converter matte in a horizontal rotating reactor at a pressure of 70 gage atm and reaction zone temperature of 180°C are used to determine the coefficient of volume heterodiffusion of copper across a copper sulfide layer.
