Problems solved by technology

In terms of flotation, the flotation copper sulfide reagents currently used in the market for copper oxide ore have strong collecting power. At the same time, it reduces the output of cathode copper in copper oxide hydrometallurgy in subsequent flotation tailings; the second is poor selectivity. In the complex copper oxide slurry flotation system, the recovery rate of copper sulfide is low, and part of the copper sulfide is lost in the tailings. In the mine, it cannot be effectively recycled, which reduces the utilization rate of resources

Embodiment 1

[0023] Example 1 Flotation of copper sulfide in a copper oxide ore abroad.

[0024] The copper minerals in the copper oxide ore are mainly malachite, chalcocite, chrysocolla and azurite, with contents of 3.76%, 1.84%, 0.68% and 0.57% respectively, followed by a small amount of blue chalcocite, copper Blue, chalcopyrite and trace bornite; other minerals include hematite, anatase ink, etc. The symbiotic relationship between malachite and chrysocolla is close, and malachite fills the intergranular and cracks of chrysocolla. Some malachite is wrapped with fine-grained chalcocite, and the output characteristics of azurite are similar to those of malachite. They are mainly distributed in the gangue in granular and irregular shapes, and the particle size of the two is relatively coarse. Some azurite and chalcocite are embedded in each other, wrapping fine-grained chalcocite. Chrysocolla is mainly embedded in the gangue in granular form, and the particle size is relatively coarse. ...

Embodiment 2

[0030] Example 2 Flotation of copper sulfide in a copper oxide ore abroad.

[0031] The copper minerals in this ore are mainly malachite, chalcocite, chrysocolla and azurite, with contents of 2.66%, 2.83%, 0.47% and 0.36% respectively, followed by a small amount of blue chalcocite, copper blue, yellow Copper ore and trace bornite; other minerals include hematite, anatase, graphite, etc. Malachite is mainly distributed in the gangue in the shape of other shapes and flakes, and secondly filled in the cracks of the gangue in the shape of veins and veinlets. The particle size of malachite is mainly inlaid with medium and coarse grains, and the distribution is uneven. Malachite and chrysocolla often have a symbiotic relationship with each other, and malachite fills the intergranular and cracks of chrysocolla. Some malachite wraps fine-grained chalcocite and blue chalcocite, and some malachite is in close contact with anatase, wrapping fine-grained anatase. The output characteris...

Embodiment 3

[0037] Example 3 Flotation of copper sulfide in a copper mixed ore abroad.

[0038] The copper ore copper minerals include malachite, chrysocolla, copper sulfide (bornite, blue chalcocite, copper blue, chalcocite), chalcopyrite, respectively, the content is 2.60%, 0.50%, respectively. 3.45% and 0.20%, other metal minerals include pyrite, hematite, magnetite and limonite. In the ore powder, malachite is mostly combined with gangue minerals and chrysocolla to form contiguous joints. No malachite monomer is found, and the particle size is coarser than other copper minerals. Blue chalcocite, copper blue, bornite and chalcocite are secondary copper minerals, the content of the first three is relatively large, and the content of chalcocite is small, and the secondary copper minerals are often combined to form conjoined particles , a small amount of bornite alternates with chalcopyrite to form conjoined bodies, secondary copper minerals mostly exist as single particles, a small amou...

Abstract

The invention belongs to the field of flotation reagents in the mineral processing discipline, and relates to a beneficiation reagent, in particular to a collecting agent for the flotation of copper sulfide from copper oxide ore and application. The collecting agent for the flotation of the copper sulfide from the copper oxide ore. The collecting agent is composed of isobutyl butyloxycarboryl thionocarbamate, xanthic acid methyl formate, ammonium dibutyl dithiophosphate, diesel oil, terpenic oil and 3# solvent oil. The flotation method for the flotation of the copper sulfide from the copper oxide ore adopts the collecting agent for the flotation of the copper sulfide from the copper oxide ore. According to the novel collecting agent for sorting copper sulfide, copper oxide and gangue minerals, the collecting agent has good selectivity and extremely high collecting capacity on the copper sulfide, can increase the recovery rate of the copper sulfide, meanwhile,and greatly reduce the content of gangue and copper oxide in copper concentrate, and therefore, the quality and the recovery rate of the copper concentrate and the hydrometallurgy cathode copper yield in subsequent steps are improved.

Description

technical field [0001] The invention belongs to the field of flotation reagents in mineral processing, and relates to a mineral dressing reagent, in particular to a collector for flotation copper sulfide from copper oxide ore and its application. Background technique [0002] In the process of sulfide ore flotation beneficiation, in order to achieve mineral separation, it is necessary to increase or decrease the buoyancy of different minerals, so as to expand the difference in buoyancy of various minerals in the pulp, and to achieve the purpose of separating different minerals. Add flotation agent. [0003] Existing copper sulfide mineral collectors include xanthates, black drugs and esters. Xanthate is the most important collector in the flotation of copper sulfide ore. Xanthate collectors have relatively strong collection capacity, but poor selectivity, and the copper concentrate entrained in complex copper ore flotation has more impurities , is not conducive to mineral ...
