中文摘要: 采用矿浆电解技术对高砷锑金精矿进行半工业试验。结果表明,锑的回收率达97%以上,金几乎全部富集于渣中,砷和硫绝大部分留置于渣中,从根本上避免了砷害和SO2危害。盐酸和电能消耗较少,每吨锑的盐酸消耗量为286 kg,总电耗为3 389 kWh,其中电解电耗1 318 kWh。

Abstract:Slurry electrolysis was successfully utilized to process As-rich antimonic gold concentrate in semi-pilot tests. The results show that antimony recovery is 97% above. Gold and most antimony and sulfur are enriched in leached residue. Hazards of generation of vast arsenic-alkali residue and low-concentration SO2 gas were avoided. The consumption of industrial hydrochloric acid is 286 kg for one ton production of antimony. Moreover, the total electricity consumption is about 3 389 kWh and the direct current consumption is 1 318 kWh for one ton production of antimony.
