在褐锰矿矿石中加入不同的添加物进行焙烧试验 ,结果表明 :在矿石中单独加入萤石或方解石混合焙烧 ,都有利于褐锰矿的氧化 ,且用量越多越好。但从环保和成本上计算 ,使用方解石比萤石环境污染小 ,价格低廉、易得 ,经济而实惠 Different additives were added into the brown manganese ores to carry out the roasting test. The results show that the mixed roasting of fluorite or calcite in the ore is beneficial to the oxidation of the brown manganese ore, and the better the amount is. However, from the environmental and cost calculations, the use of calcite fluorite environmental pollution than small, affordable, easy to get, economical and affordable
