摘要
从荷兰引进的300升采金船,存在筛上流失大粒金的问题。为提高采金船的总回收率,对筛上砾石做了回收大粒金的试验。结果表明,采用固定溜槽回收大粒金方案可行;粒级控制筛安设在砾石槽的中上部获得良好的效果;采用角钢溜格强化了选矿效益。
The dredger of 300L in volume imported from Netherlands often caused the larger grains of gold running off through the screen. In order to raise the total recovery, a test was made for retrieving large grains of gold from gravel in the screen. It showed that the fixed sluice was suitable to retrieve large grains of gold, The size control screen fixed on the above of the waist of the gravel sluice achieved good results. Also, the use of angle steel riffle strengthened the efficiency of ore dressing.
