Abstract

The beginning of new tailings storage sites pioneering has been caused by the exhaustion of the existing tailing dump capacity at Uchalinsky Mining and Processing Plant. As a result of the necessity for the forthcoming Uchalinsky quarry restoration the possibility of using quarry bowls with a large amount of waste area was studied. However, the draught from the dam pond zone, which will be formed in the current tailings discharging into the quarry bowl, will be hampered due to the lack of access to its early levels. Therefore, it was decided to thicken the pulp to pasty-like conditioning before storing.

To develop pasty pulp storage technique the physical and mechanical properties of thickened tailings have been estimated and filling solid mass characteristics were identified. It has been found that thickened pulp yields only a part of gravity wafer and it does not lose their flow properties and is subject to the yielding even in substantial thickening.
