Embodiment example

[0039] (1) The production scale of a factory is 1200t / d of tailings, and the production water consumption is 635m 3 / h, and most of its water supply is provided by the water source of the newly built pre-plant circulation system.

[0040] (2) The new φ18m-φ24m concentrator circulation return system can provide 475 m 3 / h, and put an end to the overflow of the φ24m concentrator into the green pond, reducing environmental pollution. In order to ensure that the clarity of the overflow water of the φ18m thickener meets the requirements of production volume, 45g / min of polyacrylamide cellulose is added to the overflow position of the φ24m thickener.

[0041] (3) An additional 800m in the factory 2 High-efficiency slanted-plate thickener capable of generating 153 m in situ 3 / h produced water, in order to ensure that the clarity of the overflow water of the high-efficiency thickening tank meets the production requirements, 25g / min of polyacrylamide cellulose is added to the posit...

Abstract

The invention discloses a mineral processing water-saving and emission reduction device and method. The method comprises processes of two aspects of recycling overflow liquid produced by tailings of a mining area and recycling overflow liquid produced by heavy mineral processing of a plant area; the mineral processing water-saving and emission reduction device comprises a separator, concentrators and the like, the concentrators comprise a combination of a primary concentrator and a secondary concentrator, and after concentration is performed on mineral processing waste liquor twice, the impurity content is reduced greatly; flocculants are added in a secondary concentration process, so that the impurities in the overflow liquid is further deposited, and the obtained overflow liquid is completely in conformity with the requirements of production water; in the whole process, waste liquor can be directly used for production after separation and concentration, the waste liquor treatment efficiency is improved significantly, the problems of low recovery and poor purification quality of traditional mineral processing waste liquor treatment devices are solved, apart from water quality needed by normal tailing transportation, the mineral processing waste liquor can be almost completely recycled and is not drained to nature, and environmental pollution caused by a mineral processing process can be greatly reduced.

Description

technical field [0001] The invention relates to a mineral processing waste liquid treatment technology, in particular to a mineral processing water saving and emission reduction technology and equipment. Background technique [0002] In the western region, due to the limitation of geographical conditions, there are no rivers or reservoirs around many mining areas as a fixed water source for beneficiation production, and production water is very scarce. The water source of the concentrator mainly comes from five aspects: ① The underground spring water of the tailings pond (the main water source) and the water generated after the tailings are deposited; ② The amount of domestic sewage in the mining area; ③ The amount of natural rainfall and rainwater; The amount of water produced by the concentration difference of mine transportation; ⑤The amount of return water in front of the factory. The beneficiation process requires a large amount of water resources. In order to meet the...
