Embodiment Construction

[0015] The present invention will be further described below using the drawings and examples.

[0016] refer to figure 1 , the comprehensive recovery process of nickel sulfide and copper tailings includes the following steps in turn:

[0017] Tailings sand water mining process 1, the tailings sand is made into tailings slurry with a concentration of 20-30% by high-pressure water, and then the tailings slurry is transported to the tailings gravity separation process 2 by a mine pump.

[0018] Gravity separation process 2 is to use the difference in specific gravity and particle size of minerals, and use special gravity separation equipment such as gravity beneficiation spiral chute and jig to fully and effectively extract useful minerals and valuable metals in tailings. Gravity separation process 2 consists of three stages of separation. The products sorted in the first stage enter the second stage, the tailings after the first stage enter the magnetic separation process 6, t...

Abstract

A technology for recovering the pickel sulfide-copper sulfide tailings includes water collection of said tailings sand, preparing slurry, three-segment separating, dewatering, grinding, adding the separating chemicals consisting of capture, activator, foamer, regulator and depressent, floatation, and magnetic separating. Its advantages are high productivity and recovery rate, and no secondary pollution.

Description

technical field [0001] The invention relates to the field of sorting solid materials, and is a comprehensive recovery process of nickel sulfide and copper tailings. Background technique [0002] The world's total nickel reserves are about 100 million tons, nickel sulfide and copper ore account for a quarter of the world's nickel reserves, the amount of metal is about 25 million tons, and the rest is nickel oxide ore, but the extraction of nickel from nickel sulfide ore accounts for a quarter of the world's nickel reserves. Two-thirds of the output, as a mining enterprise, especially a natural resource utilization enterprise, in the process of resource development and utilization, due to the limitations of existing technology and ore properties, a large amount of nickel sulfide and copper ore beneficiation produces a large amount of The tailings of metal resources are piled up in the tailings pool and become waste resources, but have not been effectively recycled and utilized...
