摘要
Abstract
Due to the single structure of traditional collectors,it is difficult to distinguish sulfur minerals from copper-molybdenum minerals,resulting in a large amount of sulfur entering the concentrate,affecting the quality and increasing the pressure of smelting environmental protection.In this study,a new type of composite collector was prepared by esterification-amination reaction.Using mercaptopropionic acid and oleic acid as raw materials,four groups of experimental groups with different ratios and traditional collector control groups were set up.Combined with flotation tests and adsorption capacity determination,the regulation mechanism of sulfur trend in copper-molybdenum mixed flotation was explored.The test results show that the experimental group 3(A:B:C:D=1.04:1:0.47:0.29)has the best effect.The sulfur grade of copper and molybdenum concentrates is reduced to 3.8%and 3.2%,respectively.The total sulfur recovery rate is reduced to 28.9%,and the sulfur mineral inhibition rate is 54.2%.The new collector can achieve efficient regulation of sulfur direction through the synergistic effect of composite functional groups.关键词
