The Beneficiation Introduction of Lead-Zinc Ore

Lead and zinc is one of the earlier metal that extracted out of from ore in human being. Lead and zinc are widely used in the electrical industry, machinery industry, military industry, metallurgy industry, chemical industry, light industry and pharmaceutical industry. In addition, lead metal in the nuclear industry, oil industry and other sectors also have more uses. Lead in lead-zinc minerals are 11 kinds of industries, there are six kinds of industrial minerals zinc, galena, sphalerite most important. In middle east, there are many of countries is rich of ore, one of customer from Iran, in their country, many ore mine area. And as the situation, he want to build a plant to concentrate the lead-zinc ore.

Usually, most of lead-zinc ore concentrate plant is use flotation plant to beneficiation. The galena chemical formula is PbS, is the equiaxed crystal structure, sulfur ion cubic closest packing, lead ions filling in all the octahedral voids. The fresh galena surface hydrophobicity, galena flotation unoxidized very easy, after the floating of the surface of oxide can be reduced. Yellow catching agent or black catching agent is typically galena flotation, chemical adsorption of yellow catching agent galena surface, White catching agent and (C2H5)2NCSSNa3.H2O also commonly collector, which Ammonium dibutyl dithiophosphate galena selective fishing income effect. Sulfur dioxide, sulfurous acid and its salts, lime, zinc sulfate or cooperate with other agents can inhibit galena flotation. In the sulfide copper, lead, zinc ore, often accompanied by raw iron sulfide (pyrite, pyrrhotite and marcasite, arsenic sulfide ore (such as arsenopyrite), in order to more benefits flotation of copper, lead, zinc minerals, often to add lime inhibit iron sulfide minerals.

Zinc ore flotation machine Working Principal
The motor drives the impeller to revolve, so the centrifugal effect and negative pressure are produced. On one hand, ample air is absorbed and mixed with mineral slurry, on the other hand, the mixed mineral slurry is mingled with additive, meanwhile, the foams are thinning, the mineral is bounded with foams, and floats up to the surface of mineral slurry and the mineralized foam is formed. The liquid surface can be adjusted with the height of adjustment flashboard, so that the useful foams are scraped with squeegee.

So the flotation for the lead-zinc ore is really a complex design and technology. If our clients need use the flotation plant to concentrate the lead-zinc, we will help to design build the best plant to concentrate ore. Also we can use gravity concentrate to concentrate lead ore, if the rock lead ore with good purity and particle size. After miller, we also can separate the lead from fine size lead ore slurry. Of course, the best plant design is use the flotation machine to concentrate, just need more cost of budget.
