What are tailings?

Tailings, also known as slag heap, slime, leaching slag, etc. Tailings differ from mineral coatings in that they are waste rock or other materials that cover the ore body or ore body and are lost without processing during the mining process, such as bauxite tailings. Discarding tailings at will can cause environmental pollution.

Introduction to the tailings dewatering system

Before the tailings enter the thickener, the tailings dewatering system is first used to dewater the tailings to reduce the subsequent thickener load. The tailings dewatering system has a small outer shape of about 2m*2m*2m, which is convenient for on-site layout.

The tailings dehydration system consists of dewatering screen + high-efficiency concentration cyclone unit + tailings pump tank + slurry pump.
