Description

Technical Field

[0001] The present application relates to the technical field of tailings slurry treatment, and in particular to a tailings slurry drying treatment device. Background Art

[0002] Tailings are waste materials containing useful mineral residues generated from mining or ore processing. In the process of mining and ore processing, a large amount of waste is usually generated. These wastes contain a certain amount of useful minerals, but after extraction, there are still some that cannot be completely recovered. This part of the residue is the tailings. The treatment of tailings is an important environmental and resource management issue in the mining field. Untreated tailings may have a negative impact on the environment, such as soil pollution, water pollution and ecological damage. Therefore, mining companies usually take various methods to treat and utilize tailings to minimize the impact on the environment and recover the useful resources therein.

[0003] Tailings slurry generally contains a large amount of water. Currently, incineration, landfill and other methods are mostly used for slurry treatment. However, no matter which method is used, dehydration of tailings slurry is an extremely important step. Existing tailings slurry is mostly dehydrated by filter press equipment during treatment. However, this treatment equipment is not convenient for continuous treatment of slurry. After one filter press, the mud cake needs to be cleaned, and the treatment efficiency is poor. For this reason, we propose a tailings slurry drying treatment equipment. Utility Model Content
