6.1 Process Overview 6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic,which is suitable for lead-zinc ore.But the flotation of oxidized lead-zinc ore is a difficult one. In the treatment of lead-zinc oxide ore, it is complicated to choose flotation reagent and process flow.

Lead-zinc Ore is the main ore for refining lead and zinc metal. It is the main technical process to refine lead first and then zinc in the lead-zinc ore beneficiation. Generally Zinc and Lead Mineral Processing adopts one closed-circuit three process crushing, two closed-circuits two process grinding, one rough crushing three fine grinding
Lead and Zinc Smelting Industry Description and Practices Lead and zinc can be produced pyrometal-lurgically or hydrometallurgically, depending on the type of ore used as a charge. In the pyromet-allurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sin-tering, into a primary smelter. Lead concentra-

lead-zinc ore crushing & processing Lead and zinc metal because of its special nature, plays an irreplaceable role in the industrial development. Lead and zinc metal is widely used in the field of electrical industry, machinery industry, military industry, metallurgy industry, chemical industry, light industry and pharmaceutical industry.
Evaluation of tailings from processing plants is always an important issue. Lead-Zinc ore tailings containing 3.12% Zn, 3.43% Pb, 0.71 g/t Au and 74 g/t Ag was subject to this study.
The studies of the conditions for processing the enrichment tailings of lead–zinc ore indicate the possibility of its optimization in order to maximize the involvement of waste in the production. This article presents the results of studies of a low-waste technology for processing enrichment tailings using a combined enrichment
In the lead-zinc ore beneficiation process, the commonly used equipment is a mechanically agitated flotation machine. This year, with the improvement of flotation machine technology, the modified and upgraded version of mechanical agitated flotation machine has been widely used in the newly-built concentrator.

Lead-Zinc Ore (Flotation) Processing Plant Design in Changdu County, Tibet. This lead-zinc polymetallic mine was located in the “three-river” High Mountain and canyon area of eastern Tibet and the elevation was from 3200 to 4040m.
As described in the lead-zinc ore processing section, zinc sulphate and metabisulphide sphalerite and pyrite depressants, respectively, are typically added to grinding. Then a Cu-Pb bulk concentrate is recovered with xanthate, dithiophosphate and flotation reagent blends.
The established lead-zinc ore flotation processing scheme is to add zinc sulphate (ZnSO4) to the grind to control metal ion activation (sphalerite depression). Often metabisulphide or other sulphidation chemicals are added with the zinc sulphate for iron sulphide mineral depression.
Sulfide ores are usually flotation method.Oxidized ore is beneficiated by flotation or gravity separation combined with flotation, or flotation after curing roasting, or flotation after gravity separation with sulfuric acid treatment.For lead and zinc ore containing polymetallic, magnetic – flotation, gravity-flotation, gravity-magnetic
The Processing is Novel and the Operating Cost is Lower: The regrinding process of lead-zinc mixed concentrate eliminates the need to finely grind all the raw ore, which saves the cost of grinding. At the same time, the re-grinding of the concentrate makes the lead-zinc concentrate to improve the monomer dissociation, and it has a good de-drug effect, which creates favorable conditions for the

The principal ore of zinc used for its extraction is Zinc blend ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n by coke at a temperature of 1673 K.
