本文概述了开发回收砂矿重选精矿中解理金的新型工业设备的理论与试验研究。这种新工艺是以对环境无污染的磁选法为基础的,在生产过程中避免使用汞,并获得了比混汞工艺更高的金回收率,其指标为98.6～99.5%。已开发的这种全套设备目前正在前苏联的9个金矿中投入工业应用.还有6套这种设备于1993年投入使用,其中有些设备是在独联体以外的国家中使用。这种新技术对于回收宝石(金刚石、红宝石等)半宝石(红榴石、贵橄榄石等)以及人造金刚石等是非常有前途的,在实验室研究中所得的结果是很令人鼓舞的。
This article summarizes the theoretical and experimental studies on the development of a new type of industrial plant for the recovery of gold from the redefined concentrates of sand and sand. This new process is based on a non-polluting magnetic separation process that avoids the use of mercury in the production process and achieves a higher gold recovery than the amalgamation process with an index of 98.6-99.5%. The full range of equipment that has been developed is currently being put into industrial use among the nine gold mines in the former Soviet Union, and six more are in operation in 1993, some of which are used in countries outside the Commonwealth of Independent States. This new technology is very promising for the recovery of semi-precious stones (such as diamond, ruby, etc.), artificial diamond, etc. The results obtained in laboratory studies are very encouraging.
