Embodiment Construction

[0020] The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings.

[0021] Such as figure 1 Shown, tailings of the present invention extracts construction sand beneficiation process, it is characterized in that comprising the following steps:

[0022] 1) The original tailings slurry is directly fed into the slurry mixing tank 2 from the tailings chute 1,

[0023] 2) The tailings slurry is mixed in the slurry mixing tank 2,

[0024] 3) The tailings slurry after slurry mixing is sent to the cyclone 4 by the slurry pump 3,

[0025] 4) The tailings slurry after slurry mixing and stirring is separated into sand settling and overflow in the cyclone 4,

[0026] 5) The grit separated by the cyclone 4 is fed into the dewatering screen 5, and the overflow separated by the cyclone 4 is sent to the water treatment system for recycling,

[0027] 6) The on-screen product of the dewatering screen 5 is used as...

Abstract

The invention relates to the field of tailing comprehensive development technology, in particular to a mineral separation process for tailing extraction building sands and mineral separation equipment; the mineral separation process comprises the following steps: 1) original tailing slurry is directly fed in a slurry conditioning tank by a tailing chute; 2) the tailing slurry is conditioned and stirred in the slurry conditioning tank; 3) the tailing slurry which is conditioned and stirred is fed in a swirler by a tailing pump; 4) the tailing slurry which is conditioned and stirred is separated into settling sands and overflows in the swirler; 5) the settling sands separated out by the swirler are fed into a dewatering screen, and the overflows separated out by the swirler are fed in a water treatment system for being recycled; 6) an oversized product of the dewatering screen can be used for building sands of a final product, and the undersize material is fed into the slurry conditioning tank; the mineral separation equipment is composed of a slurry conditioning tank which is provided with a stirring device, a pulp pump, the swirler, an overflow pipeline and the dewatering screen; the invention realizes tailing comprehensive development and utilization, turns waste into wealth and avoids damage of new earth and environment, thereby reducing the manufacturing cost of building works.

Description

technical field [0001] The invention relates to the technical field of tailings comprehensive development, in particular to a tailings extraction construction sand beneficiation process and beneficiation equipment. Background technique [0002] While mining enterprises extract useful mineral products in the production process, they also generate a large amount of tailings waste. The tailings produced by large mining enterprises can be as high as tens of millions of tons per year. At present, tailings wastes are all disposed of in tailings ponds, which not only takes up a lot of land, but also has certain adverse effects on the surrounding environment. How to comprehensively develop and utilize these tailings and turn waste into treasure is a major issue faced by the majority of mine science and technology workers. [0003] The analysis shows that in terms of particle size composition, physical properties, and chemical properties of some tailings, especially gravity separat...
