我国锰矿开发利用现状我国锰矿生产由解放前的几万吨发展到现在的几百万吨,由过去单一开采原矿,发展到现在的几个采、选、烧、冶联合企业,形成了一定的生产能力。在锰矿生产量中,重点国营矿山只占26%,地县办矿山占17%。群采占56%;生产品种包括冶金级锰、电池级锰和化工级锰等产品。现10个重点锰矿具有设计采矿规模200多万吨/年,选矿规模10多万吨/年。目前我国已探明的锰矿储量虽占与世界总储量的6%左右,但在总储量中含锰大于30%的
Development and Utilization Status of Manganese Ore in Our Country The production of manganese ore in our country has grown from tens of thousands of tons before the liberation to the present several million tons. From the previous single ore mining, it has developed into several joint ventures for mining, dressing, burning and metallurgy and has formed a certain Production capacity. Among the manganese ore production, only 26% are state-owned mines and 17% are mines run by counties and counties. Group mining accounted for 56%; production varieties include metallurgical grade manganese, battery grade manganese and chemical grade manganese and other products. Now 10 key manganese ore mining design with the scale of more than 200 million tons / year, the scale of dressing more than 10 million tons / year. At present, China has proven manganese ore reserves account for about 6% of the world total reserves, but the total reserves of manganese is greater than 30% of the
