Title:
COMPLEX COPPER ORE BENEFICIATION METHOD
Document Type and Number:
WIPO Patent Application WO/2015/076526
Kind Code:
A1
Abstract:
The present invention relates to complex copper ore beneficiation method. The complex copper ore beneficiation method according to the present invention comprises: a particle-size separation step which is carried out on a copper complex starting ore that contains gangue minerals and copper-containing minerals and has been crushed and ground; a first concentrate production step, for producing copper concentrate, comprising a first copper settling-out step involving the settling out of copper carried out on product of a size larger than a first reference particle size in the particle-size separation step, a copper precipitation step involving forming copper sulphide by introducing a sulphide-forming precipitation agent into the ore solution from which the copper has been allowed to settle out, and a first copper separation step involving separating out the copper sulphide by effecting further particle size separation based on a second reference particle size of less than the first reference particle size; and a second concentrate production step, for producing copper concentrate, comprising a second copper settling-out step involving the settling out of copper carried out on product of a size smaller than the first reference particle size in the particle-size separation step, a copper deposition step involving depositing copper by means of a cementation action by introducing a reducing agent having magnetic properties into the ore solution from which the copper has been allowed to settle out, a magnetic sorting step involving separating out magnetic material in the mineral solution via magnetic sorting after the copper deposition step, and a second copper separation step involving separating out copper via flotation beneficiation carried out on the magnetic material separated out in the magnetic sorting step.
