摘要
混汞提金工艺中金的回收率是重要的技术指标,研究了矿石的原矿性和生产工艺,在生产的同时同步进行了实验,考察了添汞次数、时间、Hg-Au加投量等因素,经过生产实践中进行的改进,提高了混汞板的效率,混汞提金回收率由原来的55%左右提高到63%左右。
Recovery is an important technical index in gold extraction by amalgamation The properties and production technology were introuduced, and an experiment was carried at the same tine with the produce. The frequency of adding mercury and the time of adding mercury were studied in the experiment, the effec- tion of amalgamating table was improved. The gold recovery has been lifted from 55% up to 63% economic and social benefits have been achieved.
