Tailings Recycle Wolframite Optimization Design
The wolframite is brittle and easy to smash and produce fine slime, and most of them have fine embedded granularity and more useful metal minerals. The gangue minerals are closely related to tungsten minerals, and the separation is difficult. Many fine grain tungsten can not be recycled. Then it forms tailings. Some scholars have proposed a comprehensive mineral processing scheme for recycling wolframite from tailings, including the following steps: (1) Centrifuge gravity separation and tail preconcentration, after the wolframite tailings are adjusted to pulp, the centrifugal concentrator is used to preconcentration and discarding tailings, and the concentrate and tailings of centrifugal gravity separation are obtained. (2) The concentrate is floated by the first coarse second sweep process, and the flotation tailings and sulfide ore concentrate are obtained. (3) Magnetic separation of flotation tailings by magnetic separation is carried out, and magnetic separation concentrate and ma...
