Title:
METHOD FOR FLOTATION OF COMPLEX DIFFICULT TO PROCESS COPPER SILVER SULFIDE ORE
Document Type and Number:
WIPO Patent Application WO/2023/024583
Kind Code:
A1
Abstract:
A method for the flotation of complex, difficult-to-process copper silver sulfide ore: crushing and grinding copper silver sulfide raw ore to produce ore pulp; adding a predetermined amount of a collecting agent MT-23 to perform rough selection of copper silver sulfide ore, obtaining copper silver sulfide mixed rough ore concentrate and rough selection tailings, and adding the rough selection tailings to the collecting agent MT-23 for mixed scavenging of the copper silver sulfide minerals; performing fine selection on the copper silver sulfide mixed rough ore concentrate obtained from the rough selection of the copper silver sulfide minerals, to obtain a final copper silver concentrate; the collecting agent MT-23 is a mixture of thiazidil ester, ethionine ester and polyethylene glycol alkyl ether. While ensuring the quality of the copper silver concentrate product, the recovery rate of copper and silver is significantly improved, and the process flow is simple, stable, reliable and highly applicable; the agent system is simple, with small doses of agent and convenient dosing; and problems of beneficiation in the efficient utilization of complex, difficult-to-process copper-silver sulfide ores are resolved.
