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] Example 1: as figure 1 and figure 2 As shown, a kind of beneficiation method of easy argillization and easy flotation of copper-containing talc-serpentine ore is carried out according to the following steps:

[0028] (1) Grinding: Grind the easy-mudification and easy-floating copper-containing talc-serpentine ore, and the grinding fineness is -0.074mm and the particle size content is 75%, thereby obtaining raw ore pulp;

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

[0030] (3) Separate flotation of pre-deslimed foam: ①Add copper mineral inhibitor to the pre-deslimed foam obtained in step (2), stir for 5 minutes, carry out de-slimed reverse flotation, and obtain reverse-flotation sludge foam and deslimed foam After the copper-containing gangue pulp, the reverse flo...

Abstract

The invention discloses a method for beneficiation of copper-containing talc-serpentinite ore that is easy to muddy and float. The ore is ground to obtain the raw ore pulp; (2) Pre-deliming flotation: adding a foaming agent to the raw ore pulp to perform pre-flotation of muddy and easy-to-float gangue to obtain pre-delimed foam and pre-delimed Ore pulp; (3) separate flotation of pre-delimed ore pulp: (4) individual flotation of ore pulp after pre-delimed; In addition, creatively put forward the technical scheme of suppressing copper floating mud first, then reactivating the pulp after reverse flotation desliming and copper flotation enrichment, so as to avoid the influence of a large amount of mud-containing gangue on the enrichment of copper in the pre-desilting foam , thereby greatly reducing the dosage of chemicals, thus providing a strong guarantee for improving the quality of copper concentrate.

Description

technical field [0001] The invention relates to the field of beneficiation, and relates to a beneficiation method for copper sulfide minerals, in particular to a beneficiation method for copper-bearing talc-serpentine ore that is easy to sludge and float easily. Background technique [0002] Copper is the earliest metal used by human beings. As early as prehistoric times, people began to mine open-pit copper mines and use the obtained copper to make weapons, utensils and other utensils. The use of copper has 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 ocean. The content in the earth's crust is about 0.01%. It is divided into three natural types according to the proportion of copper oxide and copper sulfide, namely copper...
