Problems solved by technology
Collectors and frothers are usually added to roughing. The best effect of conventional flotation is to use xanthate for fine-grained gold ore flotation. The effect is poor, and the recovery rate is only about 65%.

The invention relates to a collecting agent and application thereof to fine fraction gold ore flotation. According to one kind of application, a cross-linking agent Sac100 serves as the collecting agent, the cross-linking agent in this kind of application comprises the cross-linking agent Sac100 and kerosene, and the mass ratio of the cross-linking agent Sac100 to xanthate is 1.5:(6-8); the cross-linking agent also comprises polyethylene glycol, and the mass ratio of the cross-linking agent Sac100 to polyethylene glycol to xanthate is 1.5:(1-2):(6-8). According to the second kind of application, the collecting agent is applied to fine fraction gold ore flotation. By using the collecting agent, the recovery rate of -400 mesh gold ore can be increased by 5 percent points on average.
Description
technical field [0001] The invention belongs to the field of mining collectors, in particular to a collector and its application in fine-grained gold ore flotation. Background technique [0002] Collector is the most important reagent in flotation production process. The collector is a flotation agent that changes the hydrophobicity of the solid mineral surface and makes the floating solid mineral particles adhere to the air bubbles. [0003] The traditional gold ore flotation process is as follows: the ore is crushed, ore is ground, and flotation (rough selection + concentration). Collectors and foaming agents are usually added to roughing. The best effect of conventional flotation is to use xanthate for fine-grained gold ore flotation. The effect is poor, and the recovery rate is only about 65%. Contents of the invention [0004] Aiming at the defects and deficiencies in the prior art, the present invention finally mixes the cross-linking agent Sac100 and polyethylene ...
