Comprehensive recovery technology of the old workings abandoned mineral resources

Based on the analysis of the occurrence characteristics of the old workings abandoned mineral resources and mineral properties in Longshan gold antimony mines. In consideration of the actual mine production,stopping scheme with fringe drift heading and roadway across the vein and preferential fraction-mix flotation process technology on comprehensive recovery of the old workings abandoned mineral resources are introduced.Experimental research shows that: this technology offers high recoveries of gold and antimony, mining operations security, and economic efficiency significantly, the old workings abandoned mineral resources have been rational development and utilization, to provide reference for similar mines.
