Process Mineralogy Research of a Copper-containing Polymetallic Ore in Hubei Province
A copper-bearing polymetallic ore in Hubei Province is a complex refractory polymetallic sulfide ore with complex dissemination relationship and uneven dissemination size.In order to efficiently de-velop and utilize the copper-bearing polymetallic ore,a systematic process mineralogy study is carried out.The results show that the main recovery objects in the ore are chalcopyrite,galena(containing silver materi-al)and sphalerite,and the grade of copper,lead and zinc is 0.71%,1.12%and 3.56%respectively.The copper in the ore mainly exists in the form of chalcopyrite,the lead mainly exists in the form of galena,and the zinc mainly exists in the form of marmatite and sphalerite.In order to better realize the recovery of valu-able elements of copper,lead,zinc and silver,it is suggested to adopt the process flow of copper-lead bulk flotation-copper-lead separation of bulk concentrate-zinc separation from copper-lead tailings.
