How to choose the site of tailings storage

The correct choice of tailings storage site is extremely important. The design generally requires the selection of multiple sites for technical and economic comparison to be determined. The following principles should be taken into account when searching for a site:

1. a tailings pond capacity to try to accommodate all the production years of tailings volume. If there are difficulties, its service life of not less than five years is appropriate.

2. The reservoir site from the processing plant to be close, preferably located in the downstream direction of the plant. Can make the tailings transport distance shortened, the head is small, and can reduce the adverse impact on the processing plant.

3. Try to be located in the downstream direction of large residential areas, water sources, aquatic bases and key protected places of interest.

4. Try not to occupy or less occupy agricultural land and not to move or less move villages;

5. without technical proof, should not be located in the upper part of the mining value of the deposit.

6. The catchment area of the reservoir area should be small, and the longitudinal depth should be long and the slope should be slow. Can reduce the size of the flood discharge system

7. The mouth of the reservoir should be small, "stomach" to large. Can make the initial dam project volume is small, large reservoir capacity.

8. Try to avoid being located in areas with adverse geological phenomena, in order to reduce treatment costs.
