Gravity beneficiation technology for tin tailings

Tin tailing is a kind of waste produced in the production of Xikuangshan Mine, which contains a large number of useful minerals, such as tin, silver, copper, etc. In order to recycle and utilize these useful minerals, people have developed a gravity beneficiation technology for tin tailings. This article will provide a detailed introduction to the operational steps and application effects of tin tailings gravity beneficiation technology.

1、 Operation steps of gravity beneficiation technology for tin tailings

1. Ore crushing

Firstly, the tin tailings need to be crushed, usually using a jaw crusher for preliminary crushing, and then using a cone crusher for fine crushing, in order to better carry out subsequent gravity beneficiation.

2. Screening

The broken tin tailings of need to be screened to separate minerals with different particle sizes. Generally, vibrating screens are used for screening to separate minerals with different particle sizes.

3. Gravity beneficiation

gravity beneficiation is the core technology of tin tailings recycling. Its principle is to use the density difference of different minerals to separate them by gravity. Generally, a heavy medium concentrator is used for gravity beneficiation. The ore is placed in the concentrator, and heavy medium is added. After stirring and settling, minerals of different densities are separated.

4. Flotation

After gravity beneficiation, flotation is also required to further improve the recovery rate of minerals. Flotation is a technique that utilizes the different affinity between minerals and bubbles to separate minerals from the slurry. Generally, a flotation machine is used for flotation. The slurry is added to the flotation machine, and reagents and bubbles are added. After stirring and bubble action, the minerals are separated.

2、 Application effect of gravity beneficiation technology for tin tailings

The gravity beneficiation technology of tin tailings is a relatively mature mining beneficiation technology, and its application effect is very significant. Firstly, the gravity beneficiation technology of tin tailings can greatly improve the recovery rate of minerals, thereby reducing resource waste. Secondly, the gravity beneficiation technology of tin tailings can reduce environmental pollution, convert waste into useful resources, and achieve sustainable utilization of resources. Finally, the gravity beneficiation technology of tin tailings can improve the economic benefits of mines, thereby promoting their sustainable development.

In summary, the gravity beneficiation technology of tin tailings is a very important mining beneficiation technology, and its application effect is very significant. In future mining development, the gravity beneficiation technology of tin tailings will be more widely applied, making greater contributions to promoting the sustainable development of mines.
