文章概述了从砂金重选精矿中回收游离金的新型工业设备的理论和实验研究进展情况。此项新技术利用清洁的磁选法,生产过程不使用汞,与汞齐技术相比,它的金回收率较高,可以达到98.6~99.5%。开发的整套设备现已在9个俄国金矿获得工业应用。至少有6套设备预计在1993年投入使用,其中一些设备为独联体以外的国家所采用。此项新技术可以明显地回收更多的宝石(金刚石、红宝石等)、半宝石(红榴石、贵橄榄石等)和人造金刚石,这些审实也验证了实验室结果。
The article summarizes the theoretical and experimental research progress of new industrial equipment for recovering free gold from gold concentrate. The new technology uses clean magnetic separation, the production process does not use mercury, and its amalgam technology, its gold recovery is higher, can reach 98.6 ~ 99.5%. The complete package of equipment is now industrialized at nine Russian gold mines. At least 6 units are expected to be operational in 1993, some of which are used outside of the Commonwealth of Independent States. The new technology clearly recycles more gems (diamonds, rubies, etc.), semi-precious stones (garnet, peridot, etc.) and artificial diamonds, confirming laboratory results.
