Flotation agent for separating gold from gold-bearing copper sulfide ores and method for manufacturing flotation agent

Abstract

The invention discloses a flotation agent for separating gold from gold-bearing copper sulfide ores. The flotation agent comprises, by weight, 36-39 parts of sodium n-butylxanthate, 2-3 parts of carboxymethyl cellulose, 20-24 parts of n-butanol, 3-4 parts of butyl phosphate, 6-8 parts of oleic acid, 8-10 parts of diltiazem nitrile ester, 14-16 parts of isopropyl ethyl ammonium sulfate ester, 1-2 parts of salicylic acid, 2-3 parts of sodium tetrathiocarbonate, 2-3 parts of ethylene diamine tetraacetic acid, 3-5 parts of citric acid, 10-12 parts of glycolic acid and 10-12 parts of activator. The flotation agent has the advantages that the flotation agent is high in collection capacity, so that gold ores are high in recovery rate, selectivity and grade; owing to the activator, internal structures of the ores are activated, the gold collection performance of the collecting agent can be improved, various refractory gold ores are high in recovery rate, and the flotation agent is particularly applicable to separating the gold from the copper sulfide ores.

Description

technical field [0001] The invention relates to the technical field of mineral flotation, in particular to a flotation agent for selecting gold from gold-bearing copper sulfide ores and a preparation method thereof. Background technique [0002] In addition to leaching, the enrichment method of gold ore, most concentrators still choose the flotation method to recover gold minerals. At present, collectors with good collection effect on gold minerals include aniline ammonium black medicine, butyl ammonium black medicine, gold trapping agent, Y-89, M16, QF and other flotation agents. The ability is strong, but the selectivity is poor, there are problems of low gold recovery rate, large index fluctuation, unsatisfactory flotation effect, and low resource utilization. [0003] In recent years, great progress has been made in the research and application of new and high-efficiency combined flotation reagents around improving gold beneficiation indicators. In the research and app...
