METHOD FOR PROCESSING COPPER CONTAINING PRODUCTS Russian patent published in 2002 - IPC

FIELD: procession of oxidized copper ores, combined sulfide-oxidized copper ores and intermediate products, dump tails and slags including oxidized copper compounds. SUBSTANCE: method comprises steps of crushing and disintegrating initial product until fraction size exceeding size necessary for flotation; leaching and subsequently separating liquid and solid phases of product, afterdisintegrating solid phase and realizing flotation process. Liquid phase is subjected to extraction for separating purified product and copper containing solution of extracting agent. Purified product is used again at leaching. It is possible to perform reextraction of copper out of copper containing solution of extracting agent. Recovered extracting agent is used at extraction; pure copper containing solution is subjected to electric extraction; waste electrolyte after electric extraction is used for reextraction. Extraction is realized by providing contact of copper containing solution (liquid phase of product) with organic cation exchange extracting agent. EFFECT: enhanced efficiency of copper extraction, improved ecological condition of process. 3 cl, 1 dwg, 2 tbl, 2 ex
