With increasing mining depth in a gold mine,the ore property has changed.In order to efficiently develop and utilize ores from deep in the mine,systematic beneficiation experiment on the ore is carried out,which explores single flotation,gravity separation and gravity separation-flotation joint process.The results show that the gold ores have good recoverability with good single flotation index,and the grinding-classification prior to once rough-ing,three times scavenging and twice cleaning obtains the gold concentrates with gold grade 62.15 g/t,gold recovery rate 95.44 %,silver grade 150.61 g/t,silver recovery rate 74.71 %.
