I. Introduction type of manganese ore to manganese carbonate-based, 73% of the total reserves. The grade of this type of ore is very low. Generally, the grade of Mn is below 20%. Most of them are marine sedimentary and sedimentary metamorphic manganese deposits, with reserves of 39.336 million tons, mainly distributed in Yunnan, Sichuan, Hunan, Hubei, Guangxi and other provinces ( Area). Among them, the reserves of high- phosphorus manganese ore are 238.851 million tons, accounting for 60.61%. The research on enrichment and phosphorus reduction of manganese carbonate ore has been paid attention to. Second, the high-phosphorus and low-manganese manganese ore beneficiation China's manganese ore has formed a relatively complete industrial system in the selection and smelting. At present, the main methods for enriching manganese ore are re-election, magnetic separation, flotation, and enrichment by fire, or a combination of several methods. Manganese carbonate ore is mainly flotation, sometimes accompanied by re-election and strong magnetic separation. The manganese ore in a certain area of ​​Shaanxi is a high-phosphorus and low-manganese manganese ore. The ore contains low manganese (11%), high impurity phosphorus (1.10%), manganese minerals mainly manganese carbonate, and manganese oxides are rare. Manganese carbonate minerals include manganese dolomite, rhodochrosite, and manganese calcite , which account for 67.20%. Among them, mainly manganese dolomite, rhodochrosite accounts for about 8%, and manganese calcite is rare. Manganese dolomite is mainly composed of granular and vein aggregates, with a vein diameter of 0.085 to 0.1455 mm and a granular particle size of 0.0291 to 0.0485 mm. The rhombohedral ore is spherical or ring-shaped, and contains quartz fine particles or carbonaceous and shale, and the particle size is mostly in the range of 0.0485 to 0.194 mm. The gangue minerals are quartz, dolomite, calcite and the like. The harmful impurities are colloidal phosphate, which has the biological structure of mollusks, such as bryozoans and ostracods, and is connected with quartz and manganese dolomite as vein aggregates, resembling opal, crack cleavage, and cleavage along cracks. It is replaced by calcite, with a particle size of 0.1455-0.0813 mm and a small amount of fine-grained apatite. The results of multi-element analysis of raw ore are shown in Table 1, and the results of phase analysis of manganese are shown in Table 2.
