Problems solved by technology

[0005] In order to solve the flotation effect of talc and serpentine in the existing copper-bearing talc-serpentinite ore beneficiation method, a large number of polymer inhibitors are used to deteriorate the flotation slurry environment, which has an adverse effect on the effective recovery of copper minerals. Polymer inhibitors such as methyl cellulose have poor water solubility and are difficult to prepare on-site technical problems. The present invention provides a mineral processing method for copper-containing talc-serpentinite ore that is easy to muddy and float. The technical idea of ​​pre-desilting foam is firstly to suppress copper floating mud, and then activate copper minerals and sort and enrich, so as to realize the efficient recovery of copper minerals and improve the economic benefits of enterprises

Embodiment 1

[0027] Embodiment 1: as figure 1 with figure 2 Shown, a kind of beneficiation method of easily muddy, easily float copper-containing talc-serpentinite ore, carry out according to the following steps:

[0028] (1) Grinding: Grinding the ore that is easy to muddy and float with copper-containing talc-serpentinite, the grinding fineness is -0.074mm and the particle size content is 75%, so as to obtain the raw ore slurry;

[0029] (2) Pre-deliming flotation: add foaming agent butyl ether alcohol to the raw ore pulp, the dosage is 2g / t, and carry out pre-flotation of muddy and easy-to-float gangue, so as to obtain pre-deliming foam and pre-deliming pulp ;

[0030] (3) Separate flotation with pre-delimed foam: Add copper mineral inhibitors to the pre-delimed foam obtained in step (2), stir for 5 minutes, and perform desliming and reverse flotation to obtain reverse flotation mud foam and copper gangue-containing pulp after desliming, and reverse flotation desliming Foam is the...

Embodiment 2

[0037] Embodiment 2: as figure 1 with figure 2 Shown, a kind of beneficiation method of easily muddy, easily float copper-containing talc-serpentinite ore, carry out according to the following steps:

[0038] (1) Grinding: Grinding the ore that is easy to muddy and float with copper-containing talc-serpentinite, the grinding fineness is -0.074mm and the particle size content is 75%, so as to obtain the raw ore slurry;

Abstract

The invention discloses a beneficiation method of copper-containing talc-serpentinite ore easy to argillate and float, comprising the following steps of: (1) ore grinding: grinding the copper-containing talc-serpentinite ore easy to argillate and float to obtain raw ore pulp; (2) conducting pre-desliming flotation: specifically, adding a foaming agent into the raw ore pulp, conducting pre-flotation of argillization easy-floating gangue, and therefore obtaining pre-deslimed foam and pre-deslimed ore pulp; (3) carrying out independent flotation of the pre-deslimed foam; and (4) carrying out independent flotation of the pre-deslimed ore pulp. The method has the beneficial effects that firstly, the raw ore pulp is subjected to pre-desliming, so that the flotation environment of the pre-deslimed ore pulp is optimized; the technical scheme that copper floating mud is inhibited firstly, and then the ore pulp is activated and subjected to copper flotation enrichment after reverse flotation ofdeslimed ore pulp is creatively provided, so that the influence of a large amount of mud-containing gangue on copper enrichment in pre-deslimed foam is avoided, and therefore the dosage of chemicals is greatly reduced, and a powerful guarantee is provided for improving the quality of copper concentrate.

Description

technical field [0001] The invention relates to the field of ore dressing, and relates to a method for beneficiating copper sulfide minerals, in particular to a method for beneficiating ore that is easy to muddy and float copper-containing talc-serpentinite. Background technique [0002] Copper is the earliest metal used by humans. As early as prehistoric times, people began to mine open-pit copper mines and used the obtained copper to make weapons, utensils and other utensils. The use of copper had a profound impact on the progress of early human civilization. In the modern industrial system Among them, copper is widely used in electrical, defense industry, machinery manufacturing, light industry, medical equipment and other fields. [0003] Copper is a metal that exists in the earth's crust and oceans. Its content in the earth's crust is about 0.01%. It is divided into three natural types according to the ratio of copper oxide and copper sulfide, namely copper sulfide ore ...
