Manganese ore flotation column process

After flotation is a coal crusher plant of mineral particles in the two phases based on the selective attachment of the processing method. Today is the most suitable foam flotation, which is characterized by mineralization of bubbles formed by the aggregation of floating in the surface of pulp, add the pulp of the pharmaceutical stability of mineralization caused by the bubble, floating with the mineral surface can play a role in , cement roller millso that the mineral can be selectively attached to the floating bubbles on. The process is generally worn smaller mineral particles (particle size less than 0.3mm) of the pulp in the flotation machine mixing, add the appropriate flotation reagent, so that some of the wettability of mineral particles decreased, while the dispersion can be attached to the In the pulp and floating on the bubble, the bubbles on the float attached to the mineral known as concentrate, fell on the bottom or floating flotation machine does not float suspended in the pulp called tailings.

The quality of mineral flotation performance is generally used mineral surface wettability (hydrophilic and hydrophobic) to determine. Course of practice, we can flotation for change agents of Surface Properties, Kuoda mineral floatability of difference, thus improving Fuxuan efficiency and applications. Therefore, the scope of flotation wide, non-ferrous metals, ferrous metals, chemical industry and construction industry with raw materials can be used,cement feeder and particularly suitable for lean ore and fine mineral crystal, and its shortcomings is to add finely ground ore and agents, increasing costs.

Most of the carbonate coal crusher plantmanganese ore and oxide minerals, the surface is easily wetted by water, can float performance is poor, so flotation method used in industrial production less. Only the former Soviet Union's foreign chara Figure mine flotation plant and the Japanese central river flotation plant was flotation recovery of manganese mineral, but also of a general recycling facilities, small scale production, has not seen a production report .China only built Zunyi Ferroalloy Plant enriched manganese ore flotation plant.

Department of Zunyi gong well native marine sedimentary manganese ore, manganese mineral in rhodochrosite, manganese and calcite-based, iron ore mainly pyrite, marcasite, and siderite form exists, the gangue minerals are mainly carbon and clay minerals.

He was shaped granular rhodochrosite, Nickel ore dressing process mineral grains generally 0.047 ~ 0.079mm, density of 3.42 ~ 3.5g/cm3, than the susceptibility 85.7 ~ 87.1x10-6cm / g. manganese calcite single crystal is generally 0.032 ~ 0.099 mm, density of about 2.74g/cm3, single pyrite grains is generally 0.002 ~ 0.100mm Density 4.6 ~ 5.2g/cm3, than the susceptibility of 7.5 ~ 47x10-6cm / g,Cement Rotary Kiln carbonaceous clay and debris pump single crystal is generally 0.016 ~ 0.095mm according to known mineral technology research was basically all major mineral crystals occur in the ore, and general coarse grain, ore grinding to-0.074mm 80% or so, can the basic dissociation. Mine from 1959 to test the process of sorting the different indicators in Table 1 in 1975 and completed by full-flotation process 600,000 t ore concentrator (design flow and sorting process indicators shown in Figure 1, Table 2) , but production has not normal, and the rectification of the country several times, debugging. Research is continuing.
