摘要
Use of a shaft kiln in continuous smelting and refining of cement copper is made possible with a mix preheater, a refined gas preheater, an air preheater, an air mix feeder and forehearths for cement oxidation and reduction, and wherein oxidation is achieved by injecting oxidant gases and reduction by injecting preheated petroleum gas, subsequent to having placed a layer of charcoal on the smelt.
