Tungsten sand is an important metal mineral widely used in fields such as steel, aerospace, and electronics. However, the mining and beneficiation process of tungsten sand will generate a large amount of tailings, which, if not treated, will cause serious environmental pollution. Therefore, the research and application of tungsten tailings beneficiation equipment is particularly important.
1、 Treatment Method of Tungsten Sand Tailings
The treatment methods for tungsten tailings mainly include gravity separation, flotation, cyanidation, pyrolysis, etc. Among them, gravity separation and flotation are currently widely used methods.
1. Reselection
Gravity separation is a method of separating tungsten ore by utilizing its physical properties. Tungsten tailings generally contain a certain amount of tungsten ore, which can be separated by gravity separation to achieve resource reuse.
The gravity separation equipment mainly includes gravity concentrators, magnetic separators, vibration concentrators, etc. Among them, a gravity concentrator is a commonly used equipment that uses gravity to separate ores. A magnetic separator uses magnetism to separate minerals, while a vibrating concentrator uses vibration to separate minerals.
2. Flotation
Flotation is a method of separating tungsten ore by utilizing its surface properties. The surface of tungsten ore in tungsten tailings often has certain flotation properties, and tungsten ore can be separated through flotation.
flotation equipment mainly includes flotation machines, air flotation separators, etc. Among them, a flotation machine is a commonly used equipment that uses bubbles to separate minerals from water. The air flotation separator uses bubbles to separate minerals from the liquid.
2、 Development of beneficiation equipment for tungsten tailings
With the continuous progress of technology and the strengthening of environmental awareness, tungsten tailings beneficiation equipment is also constantly developing. At present, many efficient and environmentally friendly tungsten tailings beneficiation equipment has been developed both domestically and internationally.
1. Efficient beneficiation machine
Efficient beneficiation machine is a new type of beneficiation equipment that uses advanced physical beneficiation technology to efficiently separate tungsten ore and tailings. This equipment has the advantages of high sorting efficiency, large processing capacity, and low energy consumption, and is currently one of the widely used tungsten sand tailings beneficiation equipment.
2. Environmentally friendly flotation machine
The environmentally friendly flotation machine is a new type of flotation equipment that uses an environmentally friendly bubble generator to reduce wastewater discharge during the flotation process. This equipment has the advantages of large processing capacity and low wastewater discharge, making it a very environmentally friendly tungsten tailings beneficiation equipment.
3、 Application of tungsten tailings beneficiation equipment
The application range of tungsten tailings beneficiation equipment is very wide, which can be used for the treatment of tungsten tailings and the reuse of resources. At present, tungsten tailings beneficiation equipment has been applied in tungsten production enterprises, mines and other fields.
In tungsten sand production enterprises, tungsten sand tailings beneficiation equipment can convert tailings into resources, achieving circular utilization of tungsten sand production. In mines, tungsten tailings beneficiation equipment can reduce tailings discharge, protect the environment, and improve the sustainable development capacity of mines.
Summary: Tungsten tailings beneficiation equipment is a very important equipment, which can convert tungsten tailings into resources, achieve circular utilization of tungsten production, and also reduce tailings discharge to protect the environment. With the continuous progress of technology, tungsten tailings beneficiation equipment is also constantly developing. In the future, more efficient and environmentally friendly equipment will be applied to the treatment and utilization of tungsten tailings.
