Embodiment 1

[0053]Experimental design: Take copper sulfide ore with a copper grade of 1.85, add water and grind the copper sulfide ore to obtain the first slurry with a solid content of 35%, add 750g Na 2 CO 3 (the addition amount of the medicament is calculated in tons of ore, the same below). In the first ore slurry, in terms of mass percentage, the ore particles with a particle size less than 0.074mm account for 60% of the total amount of ore. The first pulp, 40g first collector and 20g C 10 h 17 The OH is mixed and stirred for 3 minutes, and the copper roughing is carried out. The flotation time is 3 minutes, and the roughing copper concentrate and the roughing copper tailings are obtained. Wherein, the weight ratio of butyl xanthate, butylammonium black drug, and ethylthiocarbamate in the first collector is 7:1.5:1.5.

Embodiment 2

[0059] The difference between embodiment 2 and embodiment 1 is that the solid content of the first pulp is 30%, the copper grade of copper concentrate and tailings is analyzed, and the yield and copper recovery rate of copper concentrate and tailings are calculated.

Embodiment 3

[0061] The difference between embodiment 3 and embodiment 1 is that the solid content of the first pulp is 40%, the copper grade of copper concentrate and tailings is analyzed, and the yield and copper recovery rate of copper concentrate and tailings are calculated.

Abstract

The invention provides a mineral collecting agent and a flotation process of copper sulfide ore. The mineral collecting agent comprises the following components in parts by weight: 6-8 parts of xanthate, 1-2 parts of black powder and 1-2 parts of thionocarbamate. The xanthate is high in collecting capacity, and black powder and thionocarbamate are good in selectivity to copper sulfide. When the three agents are mixed according to the proportion and used for flotation of copper sulfide ore, the mineral collecting agent can form a stable and uniform adsorption layer on the surface of copper sulfide, and the adsorption capacity of the three agents on the surface of copper sulfide is larger than the sum of the adsorption capacities of the three agents on the surface of copper sulfide after thethree agents are combined. On one hand, the performance complementation among the three parts is facilitated, and on the other hand, the performance of the three parts is better exerted. Based on thesynergistic effect of the two aspects, the copper collecting agent has excellent collecting capacity and selectivity. Based on the factors, the recovery rate of copper sulfide can be improved.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a mineral collector and a flotation process for copper sulfide ore. Background technique [0002] Copper is a non-ferrous metal closely related to human beings, and is widely used in electrical, light and national defense industries. In recent years, with the rapid development of my country's economy, the demand for copper is increasing. However, my country's copper self-sufficiency rate is only 30%, and there is a great contradiction between supply and demand of resources. [0003] Copper sulfide ore is enriched and recovered by flotation. The collectors used for copper sulfide ore mainly include xanthate, black medicine, sulfur nitrogen, sulfur urethane and other agents. Xanthate is the most widely used, and its collection ability is strong, but its selectivity is poor; the selectivity of black medicine is better than that of xanthate, and it has foaming propertie...
