A tailings recovery and treatment device in a quartz placer mine area

Abstract

The invention discloses a device for recycling tailings in a quartz sand mine area. The structure is simple, quartz sand tailings can be recycled well, after being screened, the quartz sand tailings are successively subjected to washing and desliming, drying and scrubbing, primary magnetic separation, treatment through a flotation assembly and secondary magnetic separation, and the quartz tailingscan be effectively utilized. Washing and desliming are implemented at first, soil in the tailings can be washed thoroughly, then the quartz tailings are slightly dried and then are scrubbed by a grinding disc, thus, iron oxide on the outer surface of quartz sand in the tailings is removed, follow-up magnetic separation is facilitated, during primary magnetic separation, the tailings are ground toone another while magnetic separation, the magnetic separation efficiency can be improved, and quartz stone can be separated from the quartz sand by the flotation assembly. During secondary magneticseparation, the iron oxide can be separated out well by strong magnetism, and the extracting purity of tailings quartz sand is greatly ensured.

Description

technical field [0001] The invention relates to a recovery and treatment device for tailings in a quartz sand mining area, and belongs to the technical field of quartz sand recovery. Background technique [0002] Quartz sand, also known as silica sand, is a common non-metallic mineral raw material with a wide range of applications. Quartz sand is mainly used in the construction industry, glass manufacturing, ceramic industry and foundry industry, which have a great demand for quartz sand. For the quartz sand mining area, when the quartz sand is mined, a large amount of tailings will be produced. At present, these tailings are generally discarded directly. This treatment method not only wastes quartz sand resources, but also causes environmental pollution and waste. Mine treatment also requires a certain cost, which leads to the ineffective use of quartz sand tailings. Therefore, how to design a recovery device for tailings in quartz sand mines in order to improve the effici...
