Tungsten Oxide

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...

Hunan Shizhuyuan Tungsten Polymetallic Mining Area is a large deposit with a variety of minerals, with up to 143 kinds of mineral varieties. It is mainly composed of tungsten, tin, bismuth and molybdenum, and is rich in fluorite, copper, lead and zinc , sulfur, iron, gold, silver, beryllium, niobium, tantalum and other minerals, the economic value is difficult to estimate. Shizhuyuan ore mineral embedded in the complex size of the mineral industry is recognized by the most difficult mineral processing. The ratio of wolframite and scheelite ore is 3:7, and a lot of fluorite, molybdenum and bismuth are associated with it. In the early stage, shizhuyuan using the traditional method of heating and flotation to 733 oxidation of paraffin soap as a collector, the total recovery of tungsten ore is only 40-50%, a large number of waste of resources to make the economic benefits of the mine hesitant. In order to get rid of the waste of tungsten resources at an early date, at the...
