Embodiment Construction

[0010] The specific steps of the technological process of the non-ferrous metal tailings recycling method of the present invention are further described in conjunction with the accompanying drawings and examples, and its features and advantages are clearer.

[0011] In the embodiment of the recycling method of non-ferrous metal tailings in the present invention, a shallow tailings pit with a diameter of 2m and a depth of 1.5m is excavated on the surface layer of the tailings pond that has been stacked for many years, and a support is fixed on the pit, and the shaft of the vertical mixer passes through The screw rod is erected on the bracket. As the tailings pit deepens, the height of the mixer can be adjusted. Install a 4″ mortar pump to inject water into the tailings pit. The amount of water injected can use the mixer to stir the tailings pit to make the tailings slurry. Use high-pressure water to wash the tailings, and use a mortar pump to extract the tailings slurry from the...

Abstract

The present invention provides a recovery method for the treatment of non-ferrous metal tailings, the main feature of which is the process of digging pits-water injection-stirring-extracting tailings slurry-ball milling-flotation-new tailings discharge and utilization, which is convenient for storage Construction and installation, no need to build a mixing tank, no need to build a new beneficiation plant, and idle beneficiation equipment can be used to reduce the amount of tailings processing, improve the grade of the selected tailings, improve the recovery rate and tailings concentrate grade, with small investment and convenient for enterprises The development and recovery enables a large number of dormant non-ferrous metal mines to be developed and utilized, and the invention is particularly suitable for closed non-ferrous metal mines.

Description

technical field [0001] The invention belongs to the field of waste recycling, and relates to a tailings re-selection method, in particular to a non-ferrous metal tailings re-selection method. Background technique [0002] my country's copper, lead-zinc, gold, and silver mines were mined earlier, and some of the tailings from the concentrators were discharged into rivers during production, and most of them were built in rivers to store tailings because the recovery rate of ore dressing was low. , the tailings contain recyclable residual metal resources. At present, many old mines have been closed due to lack of raw ore reserves, and the beneficiation plant has also stopped production, resulting in idle beneficiation equipment. Since mineral resources cannot be regenerated, the development and utilization of tailings has become an urgent task for these mines. [0003] Some tailings have been directly used by people as building materials, making blocks or firing cement, so tha...
