What is tailings?

In mineral processing, the part of the separation product that can not be used for production because of the low content of useful target components is called tailings. Tailings are a treasure to be developed. Experts believe that the current task of China mining circular economy is to develop and utilize a large number of tailings that have been shelved for a long time.

Different kinds of ores with different structures need different beneficiation processes, and tailings produced by different beneficiation processes often have certain differences in technological properties, especially particle morphology and particle size distribution.

According to the mineral processing process, tailings can be divided into the following types: manual tailings, gravity tailings, magnetic tailings, flotation tailings, chemical tailings, electrostatic tailings and photoelectric tailings. It can also be classified according to the combination and collocation of main minerals in tailings.
