Problems solved by technology

[0007] (3) The particle size is finer and the particle size range is wide
[0010] (6) The mineral composition is complex, but the specific gravity difference between tungsten minerals and main vein ores is large
However, its flotation process adopts a conventional flotation process (i.e. assembly line process) with one coarse, three fine and three sweeps. This process cannot well meet the requirements of the tungsten fine slime selection process, and there are still shortcomings and potentials.

Embodiment

[0049] Taking a polymetallic ore dressing plant in Hunan as an example, the original design production capacity of the dressing plant is 2,000 tons of raw ore per day, and two sets of SLon-3000 vertical ring pulsating high-gradient strong magnetic separators are used for rough separation of black tungsten fine mud, and flotation ( Selected) process is a conventional flotation process of one coarse, three fine and three sweep. And after adopting the mineral processing method of the present invention, economic benefit can be significantly improved.

[0050] (1) Reduce investment in concentrator

[0051] The original process flow flotation machine is configured as rough sweeping configuration GF-6m 3 Flotation machine, roughing 4 sets, sweeping Ⅰ 3 sets, sweeping Ⅱ 2 sets, sweeping Ⅲ 2 sets, selection configuration GF-3m 3 Flotation machine, select Ⅰ 3 sets, select Ⅱ 2 sets, select Ⅲ 1 set, share GF-6m 3 11 flotation machines, GF-3m 3 There are 6 flotation machines, and 1 mix...

Abstract

The invention relates to a beneficiation method combining metal accumulation with authigenic carrier flotation. A mineral product is recycled from low-grade black tungsten nonferrous metal fine mud ore, metal accumulation and black tungsten fine mud ore authigenic carrier flotation are combined, black tungsten fine mud ore flotation needs are met, the black tungsten concentrate grade is 35%, the tungsten work recycling rate is above 91%, and the tungsten total recycling rate is above 72%.

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...
