Abstract
Various stages of copper charcoal deoxidation kinetics were mathematically described with regard to the reduction stage of blister copper fire refining. It was demonstrated that the process rate was controlled by carbon mass transfer in the melt volume with metal oxygen recovery occurring to a 2-stage scheme. In order to intensify copper deoxidation it was considered reasonable to blow-in fine coal directly into the molten metal volume with inert or natural gas.
