Problems solved by technology

[0003] Aiming at a series of problems such as weak collection capacity, large dosage of chemicals and high mineral processing cost in the use of hydroxamic acid collectors in the flotation process of beta stone in the prior art, the first purpose of the present invention is to provide a compound auxiliary The key to the compound auxiliary collector is to use a compound auxiliary collector composed of sulfonated kerosene, butyl xanthate and polyethylene glycol 400 double oleate to improve the collection of hydroxamic acids. In the flotation process, the synergistic effect of compound auxiliary collectors and hydroxamic acid collectors is used to improve the collection capacity of beta stones and greatly reduce the concentration of hydroxamic acids. The amount of collector used reduces the cost of flotation reagents and solves the technical problems of existing hydroxamic acid collectors

Abstract

The present invention disclosed a reclaimed assisted capture and application for the flotation of Beta Stone.Complex auxiliary capture agents are emulsion containing sulfide kerosene, butyl yellow medicine, and 400 dual -hydrolytic acid ester.This re -reclaimed arrest collection can improve the flotation recovery effect of hydroxyric acid recipients on Beta Stone. During the flotation process, the synergies of the complex auxiliary picking agent and hydroxyl acid recruitment are used.Increase the ability to collect Bata stone, greatly reduce the amount of hydroxyl acid recruitment, reduce the cost of flotal reagents, and solve the technical problems of existing existing hydroxyl acid picking agents.

Description

Technical field [0001] The present invention involves a floating recovery agent of uranium ore, which specifically involves a complex auxiliary recovery agent for Bata stone flotation, and also involves a combination of combination of complex auxiliary recovery agents and hydroxyl acid recipients. The floating method in Beta Stone belongs to the field of uranium ore mining technology. Background technique [0002] Beta Stone is an important uranium mine resources in China, mainly distributed in Huayang Sichuan, Shaanxi Province. The reserves of this type of uranium mine have a huge reserves. According to the calculation of the amount of uranium metal metal, the scale of a large -scale uranium mine is calculated, but the level of uranium is low, only about 0.016 %. Only by significantly increased the position of uranium products through the procquare of mineral selection, abandon most of the pulse stones, and reduce subsequent water and smelting ore treatment volume, can this type...
