我国是锰矿资源比较丰富的国家之一,但在目前已探明的矿量中,能直接入炉的富矿还不多,需要经过选矿加工的矿石量很大,贫碳酸锰矿石就是其中之一种。因此,研究贫碳酸锰矿石的选矿工艺,充分合理地利用锰矿资源,是很有意义的。根据本矿扩建的要求,在昆明冶金研究 China is one of the countries rich in manganese ore resources. However, among the proven mines, there are not many rich mines that can be put into the furnace directly, and the amount of ore that needs to go through beneficiation and processing is very large, among which manganese carbonate depleted is one of them Species. Therefore, it is of great significance to study beneficiation process of manganese carbonate depleted ores and make full and reasonable use of manganese resources. According to the requirements of the expansion of the mine, metallurgical research in Kunming
