Abstract: The waste stone of non-ferrous metal ore is an important part of domestic ore resources. This type of ore is famous for its own possession of a variety of valuable metals(copper, cobalt, Molybdenum, iron, gold, silver, etc.), extremely low grade, difficulty in mineral recovery, and because it can not be effectively recycled in a timely manner, by the land disposal field and other sites to deposit, resulting in huge waste of resources and serious mine solid waste pollution. We will make use of mineral processing technology to realize efficient and comprehensive recovery of mine waste stone resources, improve existing separation processes, introduce new flotation agents, flotation columns for new flotation equipment, and separate copper and molybdenum technologies. The grade of copper concentrate increased by 4 percentage and the recovery rate increased by 3 percentage. The grade of iron concentrate increased by 3 percentage.The grade of Molybdenum concentrate increased by 6 percentage points and the recovery rate increased by 3 percentage. We will fully implement the principles of comprehensive utilization, efficient recovery and green development of waste stone resources in non-ferrous metals mines.
