Abstract

The invention relates to a method for processing pyritic copper sulphide concentrate, in which, in addition to copper, there is arsenic and gold bound to the sulphide minerals, or invisible gold. In the method concentrate is leached into a chloride-containing solution. Raw material leaching is performed in conditions where the copper, iron and arsenic of the raw material dissolve, but the gold-containing material remains undissolved. The chloride solution obtained is routed to neutralisation, where the iron and arsenic in it are precipitated. The purified copper solution is routed to liquid- liquid extraction, in the stripping stage of which copper is transferred to a sulphate solution, which is routed to copper electrowinning. Gold is recovered from the leaching residue by some known method.
