The main irregular Lead Ore Processing Plant shape chalcopyrite disseminated in an independent intergranular mineral quartz, pyrite, calcite and other minerals and broken granular fracture, these coarse chalcopyrite particle size, usually 50 ~ 100μm, greater than 1mm ; minor chalcopyrite was fine milky or irregular shape of varying sizes dispersed in sphalerite, the particle size is generally 20 ~ 70μm, fine were only 2 ~ 5μm. Flash output in the form of zinc are two kinds, which often has a black high Marmatite dense block output, coarse grains, up to 4 ~ 5mm, most of them in more than 1mm; pale yellow sphalerite disseminated in dense calcite and chalcopyrite binding surface. Most galena chalcopyrite closely with students in the periphery, the particle size is generally in 1 ~ 2μm, and some even less than 1μm. For a lead-zinc ore properties, in terms of design testing procedures, on-site construction site conditions analyzed, reasonable beneficiation process and equipment, the smooth processing plant production standards, through the processing plant design and production practices We obtained some practical experience, similar to the processing plant design has some reference guide.

Grinding and classification process design and equipment selection
Into the old concrete crusher germany ore particle size of 12mm, according to beneficiation test results, it recommended grinding fineness -0.074mm 53%, mineral grinding coarser, so the use of a segment grinding process. When using a segment grinding process, grinding machine open work is easy to produce too crushed, because some adopt a grading equipment and grinding bodies into a closed circulation. Commonly used grading equipment spiral classifier, hydrocyclones and high-frequency fine sieve, low spiral classifier grading efficiency, processing capacity is relatively small, does not match the scale of the design; low-frequency fine sieve single processing power required using multiple devices; water cyclone has a small footprint, large capacity, high efficiency grade, easy to control, etc., so grading equipment selection hydrocyclone classification. In order to support the cyclone and grading equipment, slurry pumps and reduce the wear of the cyclone, the choice of overflow ball mill.
Manganese election equipment
Our company produces manganese election calcium carbonate limestone machine to adapt to the new situation under the major mineral customer needs, the demand for, and the development of a new generation of mineral processing equipment. Products include metallurgical manganese ore, manganese carbonate powder, chemical manganese dioxide powder with manganese dioxide battery and powder. The use of manganese ore products, metallurgy sector, chemical sector and light industry sectors depending on the use of manganese ore products have different quality requirements. For steelmaking pig iron, manganese pig iron, mirror iron ore, iron content is not limited, preferably the total content of manganese and iron ore can reach 40% to 50%. In modern industry, manganese and its compounds used in various fields of national economy. Wherein the iron and steel industry is the most important areas, manganese accounted for 90% to 95%, mainly as iron and steelmaking process deoxidizer and desulfurization agent, and used to make alloys. The remaining 10% to 5% manganese used in other industries such as the chemical industry (manufacture of various manganese salts), light industry (used in batteries, matches, printing paint, soap, etc.), building materials industry (glass and ceramics colorants and bleaching agents), defense industry, electronic industry, as well as environmental protection and animal husbandry, and so on. In short, the manganese has a very important strategic position in the national economy.
