一、前言碳酸锰矿石选矿,在国外广泛应用重介质法。如美国的比尤特公司米尔利特选矿厂,印度处理硬锰矿和褐锰矿的重液选矿厂,南非上加地区的重液选锰厂,日本的稻仓石重液选矿厂。苏联各锰选厂也广泛应用重介质选矿来处理碳酸盐锰矿。锰选矿厂在国内有三个。一为遵义锰矿浮选厂,1958年建厂;二为瓦房子锰矿重介质选 I. Introduction Manganese carbonate ore beneficiation, widely used in foreign heavy media method. Such as the United States Butte Millet concentrator, India, handling of hard manganese ore and manganese ore of heavy liquid concentrator, South Africa on the region of heavy liquid manganese plant, Japan’s Kamakura Shi heavy liquid concentrator. The manganese ore processing plant in the Soviet Union also widely used heavy medium beneficiation to deal with carbonate manganese ore. Manganese ore dressing plant in the country have three. One for Zunyi Manganese Flotation Plant, built in 1958; two for Wafangzi manganese heavy media selection
