Abstract

The invention discloses an efficient iron ore concentrate and tailing slurry water recovery device which is characterized in that the device comprises a high-level water storage tank (4), a grinding and selecting workshop (5) and a concentration tank which are sequentially arranged from top to bottom; the concentration tank comprises a concentrate concentration tank (6) and a tailing concentration tank (9); the concentrate concentration tank (6) and the tailing concentration tank (9) are each provided with an overflow port, a clear water return tank (11) is arranged below the overflow ports, and clear water in the clear water return tank (11) is conveyed to the high-level water storage tank (4) through a centrifugal clear water pump I (12); and the upper layer of a tailing pond (13) is connected with a centrifugal clean water pump II (14), and the centrifugal clean water pump II (14) conveys clean water on the upper layer of the tailing pond to the high-level water storage tank (4). By designing the water recovery device for iron ore concentrate and tailing slurry, water in concentrated and neutralized tailings can be efficiently recovered, and the problem of water supply for beneficiation is solved.

Description

Technical field [0001] The present invention relates to the field of ore tap water, in particular a highly efficient iron concentrate, tail mine slurry returning device and method. Background technique [0002] A large amount of water is required in the mineralization of the iron concentrate, but some mining works are relatively far, lack of water supply, and some are difficult to take water during the dry season, often lead to production; and concentrated seed pulp and tail slurry generated after the deposit Concentration, filtration, dehydration, and storage can be separated in the storage; however, there is no efficient returning equipment. In actual production, due to geographic conditions and due to safety factors, the demand for the overall production process, the tail mines are generally siting in places where human smoke is rare, inconvenient traffic, and the tail mines and distribution workshops The distance is far, there are a few kilometers or dozens of kilometers. A l...
