本文叙述了称作“金-石蜡”法的回收金非污染工艺。它的基础是液态(熔化的)石蜡选择性地吸附在金颗粒上,然后与脉石矿物分离(矿浆冷却后)。此过程的可行性为热力学稳态性分析以及与汞齐法比较所确认。采用含金llg/t的重选精矿进行了试验。评价了某些参数,如石蜡含量、pH值和使用浮选捕收剂戊基钾黄药对金回收率的影响。得到的金回收率超过40%。 This article describes a non-polluting gold recovery process called the “gold-wax” method. It is based on the selective adsorption of liquid (melted) paraffin on gold particles and subsequent separation from gangue minerals (after slurry cooling). The feasibility of this process is confirmed by thermodynamic steady state analysis and comparison with amalgam methods. Using llg / t gold concentrates were tested. Some parameters, such as paraffin content, pH, and the effect on gold recovery using pentyl potassium xanthate, a flotation collector, were evaluated. The gold recovery rate obtained is more than 40%.
