Mathematical Model of Deoxidation of Copper by Solid Carbon

Abstract

A mathematical description is given of different stages of the kinetics of deoxidation of copper by charcoal in application to the reducing stage of fire refining of blister copper. It is shown that the mass transfer of carbon into the interior of the melt controls the rate of the process and the reduction of the oxygen of the metal is a two-step process. To intensify copper deoxidation, it has been found expedient to blow finely disperse carbon directly into the liquid metal by means of inert or native gas.
