Copper tailings treatment method

Abstract

The invention discloses a copper tailings treatment method which comprises the following steps: (1) screening: screening copper tailings so as to obtain the screened copper tailings; (2), drying: drying the screened copper tailings obtained in step (1) so as to prepare copper tailings particles; (3) sieving: sieving the copper tailings particles so as to obtain the sieved copper tailings; and (4)cooling: cooling the above sieved copper tailings to 60 DEG C or below so as to obtain the treated copper tailings. According to the copper tailings treatment method disclosed by the invention, the copper tailings are screened and the screened copper tailings are dried; then, the dried copper tailings are sieved; after the sieving operation, the sieved copper tailings are subjected to cooling treatment; accordingly, the sizes, the physicochemical properties and the like of the copper tailings subjected to the above screening operation and sieving operation can further meet the requirements forceramic preparation, and then the copper tailings subjected to the above treatment can be widely applied to the preparation of a ceramic material; and not only can the economic and environmental problems caused by the landfilling with copper tailings and other treatment methods be solved, but also the copper tailings can be turned from waste into wealth and the production cost can be reduced.

Description

technical field [0001] The invention relates to the field of processing methods for raw materials for preparing ceramics, in particular to a processing method for copper tailings. Background technique [0002] Copper tailings, also known as copper tailings, is one of the products of the sorting operation in beneficiation. It is the part with the lowest copper content of the target component, which is left after the ore is crushed and selected. And for every 1 ton of mineral copper produced, 400 tons of waste rocks and tailings will be produced, so its output is huge, and its use is not great. And it is easy to cause huge pressure on the surrounding ecological environment and safety. However, due to the narrow scope of use of copper tailings, a large amount of copper tailings are often treated as waste, and the economic cost of the treatment is often high, and it will cause great waste. [0003] Therefore, it is necessary to provide a method of reprocessing copper tailings ...

Problems solved by technology

[0004] In view of the above-mentioned prior art, the purpose of the present invention is to overcome the narrow range of use of copper tailings in the prior art. Therefore, a large amount of copper tailings are often treated as waste, and the economical treatment process is often treated. The cost is high, and it will cause great waste, so as to provide a method that can reprocess the copper tailings, so that the content of silicate in it can be further increased, so that it can be suitable for the production of ceramics, turning waste into treasure, A treatment method for copper tailings that reduces treatment costs and increases use value
