| Abstract: | To adopt the comprehensive study method including panning,polished thin section,X ray powder diffraction,scanning electron microscope,electron probe analysis etc.,the independent silver bearing minerals in Tieluping silver Lead deposits have been recognized,i.e.freibergite,native silver,argentite,stromeyerite,cuprapyrite,polybasite and bromchlorargyrite.Among them,the freibergite bacame a main silver bearing mineral in the primary ore and distributed the silver bearing inclusions over the galenite.The argentite,native silver and bromchlorargyrite are the principal silver minerals in the oxidized ore.The silver in the ore mainly hosted in the independent silver bearing minerals.Owing to the silver minerals have the impalpable granularity and complicated morphology,to adopt the flotation process or flotation process gravity separation united circuit are rather suitable.For the oxidized ore,we suggest that to adopt the circuit of the first sulphurization and then flotation process. |
