Problems solved by technology

This method has a good separation effect, and can obtain higher copper concentrate grade and recovery rate, but the use of high-alkali medium causes this traditional process to have unavoidable defects: in high-alkali medium, lime has a negative effect on the copper and sulfur in the ore. Minerals such as gold, silver, etc. have different degrees of inhibition, which is not conducive to the further improvement of copper indicators, especially not conducive to the comprehensive recovery of associated valuable metals such as gold and silver; Activator is needed to realize copper tailing sulfur separation, which causes a serious waste of resources and increases the cost of flotation; moreover, lime is used in a large amount in industrial production, which is prone to blockage, scaling, and corrosion of equipment; in addition, the alkalinity of the mineral processing wastewater in this process High, high cost of wastewater treatment

Abstract

The invention provides an inhibitor of pyrite and an application method thereof. The inhibitor of pyrite is prepared by mixing 2-3 percent of weight concentration of XS water aqueous solution and 4-6 percent of weight concentration of sodium ferrate aqueous solution by a weight ratio of (2-4):1. The inhibitor has the characteristics of cleanness, environmental protection, low dosage, good inhibitory effect to the pyrite and the like, is used for separating copper from sulfur and inhibiting the pyrite, and can effectively increase 6 percent of copper grade and 8 percent of copper recovery rate.

Description

technical field [0001] The invention belongs to the field of mineral processing, relates to the field of beneficiation and separation of complex polymetallic sulfide ores, is mainly used in the field of separation of copper sulfide and pyrite, and specifically provides a flotation inhibitor for separation of copper and sulfur and its application. Background technique [0002] With the development of society, the utilization rate of resources is increasing day by day, the properties of ore are becoming more and more complex, and the difficulty of beneficiation technology is becoming more and more difficult. The original ore of complex polymetallic sulfide ore has variable properties, close symbiotic relationship, and mutual replacement. In particular, copper and sulfur minerals are very similar in nature. [0003] At present, the lime method is the most widely used method for suppressing pyrite. This method has a good separation effect, and can obtain higher copper concentra...
