Tin ore mineral processing plant operation

The following figure  shows an integrated circuit demonstrating crushing, grinding, size separation, and gravity concentration of a tin ore.
Initial size separation is effected with a grizzly set at 11/2-in. Oversize material is fed to a jaw crusher set at 11/2-in., and the crushed product is, then, further reduced in size to 20 mesh by ball mill. The –20-mesh material is classified by hydrocyclones set at 150 mesh, and the –150 mesh material is sent to shaking tables to concentrate the heavy tin mineral, cassiterite. The middlings in this process receive additional treatment. The concentrate from this operation is reground and sized at 200 mesh. Two-stage vanning is used to produce a fine tin concentrate.

How to extract silica sand from kaolin tailings?

图片
This paper describes in detail the method of extracting silica sand from sandy kaolin tailings, which can make full use of tailings and improve the application value of kaolin tailings. Its silica sand concentrate fully meets the requirements of glass quartz sand index. Kaolin and its tailings Kaolin is an important non-metallic mineral material. It is not only a necessary raw material for building materials, light industry and other traditional industries, but also a basic material for the development of modern industry. Kaolin mineral resources are continuously exploited and utilized, and a large number of tailings will be produced in the process of mining and processing of kaolin, and the number of tailings will increase year by year. The continuous accumulation of tailings occupies a large amount of land, which affects the ecological environment and also causes the waste of mineral resources. The treatment methods of Kaolin Tailings mainly include: building t...
