加拿大安大略省湖岸(Lake Shore)金矿,为了从附近老矿山的尾矿中回收黄金(含金约2克/吨),并回收部分矿柱(含金约13克/吨)。这两种原料都必需磨得极细,才能达到金的单体分离。在设计中采用塔磨机(矿柱用老虎口,半自磨、塔磨)将两种原料都磨到90%-400目,用碳浆法代替原来的锌粉置换法,简化了工艺和解决了过滤等问题。选矿厂日处理2000吨矿石。(一)塔磨机的发展随着现代技术的发展,要求有些研磨设备,既要比球磨机效率高,又能研磨出更细的产品。近年来,一些设计部门已开始采
The Lake Shore gold mine in Ontario, Canada, is to recover gold (about 2 g / t gold) from the tailings of the old mines nearby and recover some pillars (about 13 g / t gold). Both of these raw materials must be very finely ground in order to achieve gold monomer separation. In the design of the tower mill (ore column with a tiger’s mouth, semi-self-mill, tower mill) will be two raw materials are ground to 90% -400 mesh, with the carbon slurry instead of the original zinc powder replacement method, simplifying the process and Solve the filtering and other issues. Concentrator daily processing 2,000 tons of ore. (A) the development of tower mill With the development of modern technology, require some grinding equipment, both higher than the ball mill efficiency, but also grinding out a more detailed product. In recent years, some design departments have begun mining
