1. First of all, we should try our best to comprehensively recycle the useful components of tailings resources, and use advanced technology and reasonable technology to re-select the tails to maximize the recovery of useful components in the tailings, which can further reduce the amount of tailings. . Some concentrators are developing towards tailings.

2. Tailings are used as filling materials for underground mining mined areas of mines, that is, aggregates filled with water sand or cemented. The tailings are used as filling materials for the goaf. The most ideal filling process is the full tailings filling process, but it is still in the experimental research stage. The production uses the coarse fraction in the tailings as the filling of the goaf. After the tailings of the ore dressing is discharged, the tailings preparation section is sent for classification, and the coarse sand part is sent to the gob area, and the fine part is stored in the tailings storage. This tailings treatment method has been applied at home and abroad.

3. Using tailings as raw materials for building materials: making cement, silicate tailings brick, tile, aerated concrete, cast stone, refractory material, glass, ceramsite, concrete aggregate, glass-ceramic, slag brick, Foam glass and foam, etc.

4. Use the tailings to build roads, pavement materials, non-slip materials, and coastal fields.

5. Covering the soil on the tailings dumping site, planting crops or planting trees.

6. The tailings heap is stored in a specially constructed tailings pond. This is the most widely used tailings treatment method in most concentrating plants.
