Embodiment Construction

[0020] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] refer to figure 1 , in this preferred embodiment, a kind of dehydration desliming process for mineral processing flotation, comprises the following steps:

[0022] Put the sulfide ore pulp to be processed into the mixing tank, add the chemical agent, and fully stir the chemical agent and the pulp evenly;

[0023] Feed the minerals into a horizontal screw centrifuge for processing, so that the ore pulp is centrifuged at a high speed to obtain deslimed solid materials and muddy wastewater;

[0024] The deslimed solid material centrifuged by the horizontal screw centrifuge is stirred with clean water, and the concentrate is separated by flotation.

[0025] The main function of the horizontal screw centrifuge is high-speed centrifugation, which is accompanied by the friction and stratification between different m...

Abstract

The invention discloses a dehydrating, reagent removing and desliming process for ore dressing flotation. The process includes the following steps that sulfide ore pulp needing to be treated is fed into a stirring barrel, a reagent is added, and the reagent and the ore pulp are fully stirred to be uniform; ore is fed into a horizontal spiral centrifuge to be treated, the ore pulp is centrifuged at high speed, and slime-removed solid materials and slime-containing wastewater are obtained; and the slime-removed solid materials centrifuged by the horizontal spiral centrifuge and clean water are stirred, and concentrate is selected out through floatation. According to the dehydrating, reagent removing and desliming process for ore dressing flotation, the three effects of dehydrating, reagent removing and desliming are combined together through the horizontal spiral centrifuge, recurring pulp mixing of the complex ore pulp is achieved, the problem of ore dressing work is solved, and the floatation efficiency is improved.

Description

technical field [0001] The invention relates to the field of ore dressing and flotation technology, in particular to a dehydration, drug, and mud removal technology for ore dressing and flotation. Background technique [0002] Slurry properties are an important factor affecting mineral flotation. In beneficiation operations, the dissolution of minerals, the addition of beneficiation agents and the generation of intermediate products will have a major impact on the slurry system. [0003] In the beneficiation operation, the grinding and dosing of the upstream flotation process will cause the mineral particle size in the subsequent flotation pulp to become finer, or even muddy. Flotation efficiency. Contents of the invention [0004] The main purpose of the present invention is to provide a dehydration, chemical and desliming process for ore dressing and flotation, aiming to make sulfide ore re-sizing have good selectivity and improve flotation efficiency. [0005] In ord...
