在选金厂中,尽一切可能提前回收已单体分离的金粒,对减少金的损失,提高金的回收率以及降低选矿成本都是重要的。由于金的比重大、性软、展性强等特点,在磨矿过程中已经单体分离的金粒,很容易存留在球磨机的衬板间的缝隙中、分级机槽底的角落处以及钢球的孔隙中。单体分离的金粒存留在这些地方,长期不能排出,最后在检修分级机、球磨机以及清理钢球时,势必造成这些单体分离的金粒的损失。笔者曾把这些沉积物放到显微镜下观察,发现其中有大量的金粒存在,其数量是极可观的。笔者也曾
In the gold foundry, doing everything possible to recover gold that has been monomer separated in advance is important for reducing gold losses, increasing gold recovery, and reducing ore dressing costs. Due to the large proportion of gold, soft, strong exhibition and other characteristics, in the grinding process has been the monomer separation of gold particles, it is easy to remain in the gap between the ball mill liner, grader bottom of the groove at the corner and the steel In the pores of the ball. Monomer separation of gold particles remain in these places, long-term can not be discharged, and finally in the maintenance of graders, ball mill and clean up the ball, it is bound to cause the loss of these separate gold particles. The author put these sediments under the microscope to observe and found that there are a large number of gold particles exist, the number is extremely impressive. I have also
