Collecting agent for copper and gold ores and method for manufacturing collecting agent

Abstract

The invention discloses a collecting agent for copper and gold ores. The collecting agent comprises, by weight, 20-23 parts of diltiazem nitrile ester, 20-23 parts of ammonium dibutyl dithiophosphate, 3-5 parts of naphthenic acid, 2-3 parts of oxidized paraffin soap, 3-4 parts of sodium dodecyl benzene sulfonate, 1-2 parts of sodium napthionate, 3-4 parts of sodium oleate, 3-4 parts of sodium fluoride, 7-9 parts of O-alkyl-N-alkyl sulfide thionic carbamate, 6-9 parts of dimethylglyoxime and 10-12 parts of activator. The collecting agent has the advantages that collecting and foaming effects can be realized by the collecting agent, foams are stable, the collecting agent is high in collecting capacity, gold ores are high in recovery rate, selectivity and grade, a copper suppressing effect can be realized, and copper can be prevented from being collected; owing to the activator, surface hydrophobic properties of the gold ores can be changed, internal structures of the gold ores can be activated, the gold collection performance of the collecting agent can be improved, and gold is high in recovery rate and grade.

Description

technical field [0001] The invention relates to the technical field of mineral flotation, in particular to a collector for copper-gold mines 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 application of new high-efficiency pharmaceu...

Problems solved by technology

Although the research on gold ore flotation reagents has made great progress, some carbide adsorbents or other reasons will cause a certain degree of gold loss during the flotation process. loss to business and society
