The beneficiation method of Bosite high-indium high-iron zinc sulfide concentrate, and the mixed flotation process of low-grade lead-zinc ore

The beneficiation method of lead-zinc ore is mainly flotation, but for low-grade lead-zinc ore, flotation is the main beneficiation method. Ore beneficiation often requires the use of other methods for pre-enrichment to reach a certain grade, thereby reducing transportation costs and improving the effective grinding rate of grinding equipment. Gravity separation is an energy-saving, efficient and environmentally friendly mineral processing method. It is often used as a method for pre-enrichment of low-grade lead-zinc ores. Henan Bosite Machinery Manufacturing Co., Ltd. hereby briefly introduces the gravity separation and enrichment of lead-zinc ores, hoping to be helpful to relevant people.
The embedded particle size of lead-zinc ore is generally fine, so the raw ore needs to be crushed and ground to reach a certain degree of monomer dissociation before pre-enrichment can be carried out. In the gravity separation and enrichment of lead-zinc ore, it is often Through two stages of crushing and one stage of rod mill, the ore particle size is controlled at around 10%, and then enters the jig for gravity separation and enrichment. After reaching a certain grade, it enters the flotation process to reduce the cost of mineral processing.
As an energy-saving, environmentally friendly and efficient mineral processing method, gravity separation is often used as the primary method for pre-selection and enrichment. It is used as a pre-selection in gold ore, antimony ore, mercury ore, lead-zinc ore and other minerals. The process pre-concentrates low-grade raw ore. The use of combined heavy-floating technology can also reduce the cost of mineral processing to a great extent, thereby increasing the profit of mineral processing.
