Tailings Disposal Method

Tailings disposal method

Depending on the mineral processing methods, the main methods of tailings disposal. At home and abroad , the tailings nature of the differences also have different comprehensive utilization of the tailings resources can be summarized as the following several ways:

1, we must first try to do the useful components of the tailings resource recycling, the use of advanced technology and reasonable process for re-election to the tailings to maximize the recovery of useful components in the tailings, which can further reduce the tailings number of some of the concentrator to the development of non-tailings direction.

2, Tailings is used as filling material of the underground mining goaf, that the aggregate of water, sand filling material or cement filling. When tailings are used as a filling material of the goaf, the best filling technique is filling technique of the whole tailings . But it still stay at the pilot study stage. In the production , always use the coarse part of the tailings as the filling of the goaf . The concentrator tailings are discharged , then sent into evacuation tailings section grading. The rough sand part are sent into the underground goaf, and fine-grained part into the tailings stockpiles. This method of tailings disposal have been applied at home and abroad.

3, Tailings as raw materials for building materials: production of cement, silicate tailings bricks, tiles, aerated concrete, cast stone, refractories, glass, ceramic, concrete aggregate, glass-ceramic, clinker tiles, foam glass and foam materials.

4, Tailings construction of a highway, road surface material, non-slip material, coastal farmland.

5, accumulate in the tailings field casing farmland, grow crops or reforestation.

6, tailings are pile up at specially built library , which is the majority of the tailings concentrator currently the most widely used approach.
