含砷难处理金矿浮选研究进展

随着易处理单一金矿储量不断减少，含砷难处理金矿所占比重越来越大。此类矿石普遍采用浮选法处理，总结含砷难处理矿石浮选技术研究进展有重要意义。浮选药剂的研发是含砷金矿分选技术的重点，近年来高选择性捕收剂和砷抑制剂的研发和应用取得了较多进展，浮选工艺研究也取得了创新性成果，而新型捕收剂及砷抑制剂的研究应用和浮选联合工艺开发是未来含砷难处理金矿研究的主要方向。

Research Progress of the Arsenic-containing Refractory Gold Flotation

With the increasingly exhausting of easily leachable gold ores，the proportion of refractory gold ores which containing arsenic is growing larger.The ores were dealt commonly with the flotation method，and summarizing the flotation technology of refractory gold ores which containing arsenic is very important.Obviously，research and development of the flotation reagent is the key to the flotation technology of the containing arsenic gold ores.In recent years，it has made more progress for the development and application of the high selective collector and arsenic inhibitors.And the research on flotation also has made innovative achievements.In short，the development and application of the high selective collector and arsenic inhibitors and the exploitations of combined processes are the main directions for the research of refractory gold ores which containing arsenic.
