南非的Ｍ .格雷克等撰文描述了能够使含有黄铜矿和黄铁矿的精矿氧化的极度嗜热细菌。在 70℃条件下实施的批量试验表明 ,铜的萃取率可达到 98%。进行了三阶段的半工业连续试验 ,采用的是标准设计的机械式搅拌充气槽。文章评价了停留时间、给料细度和氧气及二氧化碳的物料传输总
An article by M. Grecke et al. In South Africa describes extremely thermophilic bacteria capable of oxidizing concentrates containing chalcopyrite and pyrite. Batch tests carried out at 70 ° C showed copper extraction rates of up to 98%. A three-phase semi-industrial continuous test was carried out using a mechanically designed aerated tank of standard design. The article evaluates residence time, feedstock fineness, and the total amount of oxygen and carbon dioxide delivered to the material
