Abstract
Cement copper, in non-briquetted form, is melted down and refined in an internally heated rotary drum furnace. The cement copper is so charged as to lie on the bottom and both side walls of the furnace and preferably has a moisture content of 6 to 15 per cent, produced by drying and re-moistening, or is preheated to between red heat and its melting point in a drum or circular furnace provided with rabbling arms.
