TECHNOLOGY TO PROCESS SLAG CARRYING COPPER AND NICKEL Russian patent published in 2000 - IPC

Abstract RU 2158771 C1

FIELD: non-ferrous metallurgy. SUBSTANCE: technology to process slag carrying copper and nickel includes crushing, grinding, classification of material, its separation into copper and nickel products and their further processing. Grinding is carried out in two stages with extraction of metallized fraction of slag with size +60 mm at first stage, additional grinding of minus fraction at second stage with use of metallized phase of first stage of grinding in the capacity of grinding bodies. Grinding is conducted in self-grinding mills. EFFECT: simplified technology thanks to exclusion of operations of medium and minor crushing and bringing of metallized fraction from grinding cycle. 1 dwg
