| Abstract: | A process of acid leaching under pressure of polymetallic sulphide flotation concentrates and various influence factors on leaching is studied.The results show that more than 99% of zinc and more than 90% of copper in complex concentrates can be leached,while more than 98% of lead and silver left in the residue,and the recovery of sulfur is about 70% under an unfastidious condition. |
