Manganese carbonate ore beneficiation process and method Carbonate ores are primarily mineral rhodochrosite, rhodochrosite, calcium, manganese, manganese calcite and siderite iron ore; gangue silicate minerals and carbonate minerals, but also frequently with sulfur and iron and other impurities. The composition of the ore is relatively complicated. The size of the manganese mineral inlay is as small as a few microns, which is difficult to dissociate and it is difficult to obtain a higher concentrate grade. Most of the manganese carbonate ore beneficiation methods use strong magnetic separation, heavy medium ore dressing and flotation. Sedimentary manganese sulfate-containing ores generally employ a sequential preferential flotation process of carbonaceous shale , pyrite and manganese minerals. Hydrothermal manganese ore containing zinc-carbon generally lead flotation - strong magnetic separation process. Some sulfur-rich manganese ore, manganese minerals are mainly sulphur-manganese ore, generally using roasting method to remove sulfur. Some manganese carbonate-rich ores are also produced by roasting to remove volatile components to obtain finished ore. Manganese carbonate ore contains some refractory ore. Manganese is closely symbiotic with iron, phosphorus or gangue. The size of the inlay is extremely fine and difficult to sort. It can be treated by smelting method. For example, high iron and manganese ore processing high-phosphorus manganese-rich slag, production of activated manganese dioxide and nitric acid leaching of gold electrolytic production method and the like have been used in the case of industrial production of manganese. In addition, there are calcium disulfate method and bacterial leaching method.
