lead zinc benefication

Lead and Zinc Lead and zinc ores are usually found together with gold and silver A leadzinc ore may also contain lead sulfide zinc sulfide iron sulfide iron carbonate and quartz When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals The remaining rock and minerals are called gangue

Leadzinc ore beneficiation process can be applied to the mass production of sulfur leadzinc ore Technology Advantage Generally it adopts one closedcircuit three process crushing two closedcircuits two process grinding one rough crushing three fine grinding three scavenging lead flotation process，one rough crushing three fine grinding three scavenging zinc flotation process

BENEFICATION OF LEAD ZINC ORES LEAD and Zincb are very important nonferrous ase metals used in the metallurgical and chemical industries So far the only workable leadzinc deposit exists in Zawar mines of Rajasthan Recently some more leadzinc deposits are also being developed in the Agnigundala area in Guntur district of Andhra Pradesh

At the macro level the leadzinc mine can be divided into three subsystems including the underground mine processing plant and support systems The average grade of ore is 425 for lead 772 for zinc and 2465 for sulfur Additionally there are a few rare metals and heavy metals in the ore

Minerals of lead and zinc commonly are rather closely associated in nature zincfree lead ores and leadfree zinc ores are exceptional rather than common although there are such Lead and zinc ores usually contain some silver but those of the Mississippi Valley region are silverfree Indeed leadzinc ores often are commercially valuable chiefly because of their silver and sometimes gold content

Lead and Zinc PbZn Separation Process Circuit Primary Washing and Crushing Lead Ore Grinding Circuit Lead Flotation and Tabling Regrind Circuit Zinc Flotation SUMMARY Flotation of Lead Ore The flowsheet above was designed to treat economically approximately 200 tons in 24 hours of a lowgrade dump ore containing lead and zinc values as well as some silver in both sulphide and oxide form

The excess of sodium sulfide acts as depressant for oxidized lead and zinc minerals because adsorption of divalent sulfide ions on the surface of lead oxide minerals increases the negative charge which prevents the adsorption of the collector on to oxidized zinc mineral surfaces

su lfides first Then if present the zinc sulfide is floated followed by the flotation of lead minerals Either sodium sulfide or sodium hydrosulfide is used as a sulfidizing ag ent Önal et
