Zinc Ore Dressing Production Line

Usage:

Zinc is a very important kind of non-ferrous metal, the product with this element has[pic] a widely usage and a great demand. It can be used as coating of anticorrosive food, automobile manufacturing, mechanical industry, zinc containing gold casting, dry cell, rubber paint, enamel, medicine, printing, fiber, etc.

The kind of zinc ore:

there are so much ore within zinc element, such as sphalerite, rhombohedrons zinc mine, red zinc mine, silicon metal, sphalerite iron, etc. Ens is a point of zinc ore dressing. The density of zinc ore is 3.9-4.1 t/m³, hardness is 3.5-4.0. Because the raw ore is different, the beneficiation process is different, it is not derivative. It is need to make a small beneficiating trial to ensure the reasonability of process. Our China is a country with a big mount of zinc. America, Australia, Canada, Mexico, Peru are main origins of zinc in the worldwide.

The beneficiating ways of zinc ore:

For low grade containing zinc ore, washing is the necessary method, then it became zinc concentrate. The grade of zinc concentrate is 40% at least, and the impurity content is not exceeded the standards of national and metallurgy enterprise. Our undressing zinc ore’s grade is between 1% and 7% generally, some respective ore’s grade is up to 10%. Flotation is the main method for zinc ore dressing. Because of accreting with lead content, copper content and sulfur mineral, different separating ways are used: for metal sulfide ore, traditional way is flotation primary and mixed rough concentrate then separation, that is select lead firstly, then copper zinc separation or zinc silicon separation; for sulfide deposit, the general way is: flotation with selecting lead firstly, then selecting zinc.

For mixed ore like sulfide ore and oxide mineral, the general flotation order is sulfide ore selected and then oxide zinc ore floated adding sodium sulfured as activator.

For the oxide zinc which is difficult to select. First adding the sodium sulfured...
