Fairview金矿位于南非的东特兰斯瓦尔地区,处理难浸硫化矿。主要的硫化矿物是黄铁矿、砷黄铁矿。金以次显微颗粒赋存于黄铁矿、砷黄铁矿晶粒中。 1984年细菌氧化中试厂由Gencor集团研究中心建成,以750kg/d的规模处理Fairview的精矿。经过中试厂两年的运转,确定了设计和运行参数。工业化细菌氧化厂的设计为每日几吨的规模,它于1986年10月建成投产。该厂运行十分成功,作为全流程的一部分,它处理40％的浮选精矿并获得了95％的回收率。由于不断完善,该厂目前每日可处理12t。对温度、给矿速度、空气及pH值这些操作参数的仔细控制使得全厂运行良好。Fairview细菌氧化厂经过24个月的生产运行证明,该工艺无论从技术上还是从经济上都是完全可行的。
Fairview Gold Mine is located in the East Transwar region of South Africa, handling difficult-to-sulfide sulphide ore. The main sulphide minerals are pyrite, arsenopyrite. Gold sub-microparticles occur in the pyrite, arsenic pyrite grains. The 1984 Plant Oxidation Pilot Plant was built by the Gencor Group Research Center to process Fairview concentrates on a 750kg / d scale. After two years of pilot plant operation, to determine the design and operating parameters. Industrial Bacteria Oxidation Plant was designed to be on the order of a few tons a day and it was put into operation in October 1986. The plant ran very successfully and as part of the overall process it handled 40% of the flotation concentrates and achieved a 95% recovery rate. Due to continuous improvement, the plant currently can handle 12t daily. Careful control of operating parameters such as temperature, feed rate, air and pH make the plant work well. Fairview Bacteria Oxidation Plant After 24 months of production runs, this process is completely technically and economically viable.
