本文报导利用存在于硫化物矿坑水中的氧化铁硫杆菌和氧化硫硫杆菌,在通气条件下,将黄铁矿氧化后产生硫酸和硫酸高铁溶液,在不补加硫酸的情况下,用以浸出陕西汉中天台山锰矿中的硫锰矿和碳酸锰等矿物,获得与完全用硫酸浸出相同的浸出效果。这对锰矿区附近缺酸而黄铁矿资源又很丰富的地区,处理氧化锰类型矿物有其实用意义。 This paper reports the use of Thiobacillus ferrooxidans and Thiobacillus thiooxidans present in sulphide pit water to oxidize pyrite to produce sulfuric acid and high-speed ferric sulphate solution under aeration conditions and to leach The minerals such as manganese and manganese carbonate in the Tiantaishan manganese mine in Hanzhong, Shaanxi Province, obtained the same leaching effect as the sulfuric acid leaching. This is manganese ore area near the lack of acid and pyrite resources are very rich areas, the treatment of manganese oxide type minerals have practical significance.
