Description

technical field

[0001] The invention belongs to the technical field of mineral product recovery, in particular to a beneficiation method combining metal accumulation and self-generated carrier flotation. Background technique

[0002] my country is a country with a large amount of tungsten resources and is extremely rich in tungsten resources. It is the largest producer of tungsten concentrates in the world. Black tungsten is mainly recovered by gravity separation. Since the first mechanized tungsten beneficiation plant was built in 1953, the reform and research of tungsten beneficiation process has been carried out, and the research of black tungsten fine slime beneficiation process has made great progress , there have been many new processes, new equipment, and new agents, and a wealth of research and production experience has been accumulated. Studies have shown that wolframite is brittle, brittle and easy to muddy in the process of crushing and grinding, and the yield of...
