Wolframite has a large proportion and is brittle. Slime is easily produced in the process of mining and dressing. In the early stage, shaking bed and centrifugal gravity separation are mainly used to recover wolframite. Shaking bed surface zoning is obvious and easy to operate, but the unit area processing capacity is small, the recovery rate is low when treating fine mud, and metal is easily lost from fine mud. Although centrifugal concentrator has large processing capacity and high recovery efficiency for fine mineral particles, its water consumption is large, and it is difficult to achieve ideal indicators in actual industrial production.

There are a large number of X, gamma rays and neutrons in the radiation field environment of nuclear power plants and nuclear power plants. In order to ensure absolute safety, these X, gamma rays and neutrons need high-density radiation shielding materials. At present, the commonly used materials are lead-boron polyethylene, boron-containing polypropylene, cadmium plate, boron steel, tungsten-based heavy alloy, boron carbide and aluminium-based boron carbide. The above materials are only lead-boron polyethylene. Material can shield x, gamma rays and neutrons at the same time. Other materials can only shield one of the x, gamma rays or neutrons.
