Embodiment Construction

[0029] figure 1 The above background technology has been described, here is a brief description:

[0030] After the raw ore enters the screening system, it is screened immediately to separate the products on the upper sieve. The second-stage mill processes the jigging first, second, and third-room concentrates and the tailings in the floating bed. The spiral classifier and the second-stage mill are closed. Its overflow enters the full flotation of sulfide ore.

[0031] figure 2 Shown is the invention for figure 1 Improvement of the grinding production process:

[0032] The raw ore is screened into three products. The material larger than 4mm enters the raw ore and grinds to a particle size of less than 3mm, accounting for 70%. Then enter the stage floating system for sorting. The raw ore mill here starts the first sub-step, and the jigging first room, second room, third room and tailings enter the 8# mill, 3# mill, and 4# mill for the second step. Three-branch grinding, ...

Abstract

The present invention relates to the non-ferrous ore milling and separating process. The process includes sieving the crude ore into three size fractions, including 4 mm over fraction to the ore mill for milling to 3 mm below size, 2-4 mm fraction to the jigger for enriching and 2 mm below fraction to the screw chute system for enriching and to the table floating system for separating; milling crude ore in the crude ore mill; enriching in the jigger; grading after milling; separating in the table floating system and the screw chute system to obtain ore concentrate; and milling the concentrated tailings to recover target metals before draining ore slag. The present invention has sufficient milling and high metal recovering rate.

Description

technical field [0001] The invention relates to a method for grinding and sorting one or more metal minerals, especially a process for preventing over-crushing of minerals with multiple components during the grinding process. Background technique [0002] Grinding is the most important link in the beneficiation process. Due to the different dissociation degrees of monomers of different minerals, the particle size states required for flotation separation and gravity separation are different, so the requirements for grinding particle size are also different. At present, there are still It is to grind the raw ore to the particle size required by the sorting operation at one time, or to grind the raw ore to 3-5 mm first and then to the required qualified size after the second stage of grinding in consideration of factors such as grinding ratio, energy consumption, material consumption, and particle size. Particle size, which is very common in chemical, metal and non-metal benefi...
