subject: Manganese Ore Processing Plant [print this page] a. high intensity magnetic separationa. high intensity magnetic separation
Manganese compound belongs to the weakly magnetic minerals [XMAX, X = 10 10-6 600 10-6cm3 / g,], in a strong magnetic field of the magnetic field strength Ho = 800 ~ 1600kA / m (10000 20000oe) separator be recovered, the general progress of manganese grade of 4% to 10%.
Magnetic manipulation is simple, easy to control, strong adaptability, and can be used for a variety of manganese ore sorting, in recent years has been dominated in the manganese ore. New types of coarse, medium and fine-grained magnetic machine has been developed and successfully. At present, the most common manganese, medium-grained strong magnetic separator, coarse and fine strong magnetic separator has gradually been applied , while micro-fine strong magnetic separator is still at an experimental stage.
b. weight - magnetic separation
Weight manganese - magnetic separation plant mainly deal with the leaching of oxide ore, the use of AM-30 jig handle 30 ~ 3mm of washed ore, manganese available to more than 40% of the quality manganese ore, and then handled the election impurity can be used as battery manganese raw material. The jig tailings and less than 3mm wash mine diameter grinding to less than 1m, with a strong magnetic separator, sorting, manganese ore grade are improved by 24% to 25%, up to 36% to 40%.
c. Magnetic - flotation
Current magnetic - flotation process is only suitable for manganese. The mine is a manganese carbonate-based, low manganese, low phosphorus, iron ore.
c. Fire enrichment
Fire enrichment of manganese ore can deal with high phosphorus, high iron refractory poor manganese ore, a sorting method, commonly known as the manganese-rich slag. The nature is really the use of the reduction temperature of manganese, phosphorus, iron in the blast furnace or electric furnace to control its temperature to a high temperature for the selective separation of manganese, phosphorus, iron and sorting.
Pyrometallurgical enrichment process is simple, stable production, and iron ore, phosphorus can be effectively isolated to, and get rich manganese, low iron, low phosphorus and manganese-rich slag, this rich manganese slag containing Mn35% to 45% of the general , Mn / Fe 12 ~ 38, the P / Mn
