preparation example Construction

[0013] The preparation method of the collector for copper-gold ore is as follows: mix other components except the active agent, stir at 48° C. at 11,000 rpm for 13 minutes, then add the activator, and stir at 7,000 rpm. Stir for 25 minutes and serve.

[0014] Experimental data

[0015] When flotation is performed on copper-gold ore with raw ore grade of 6.70g / t, when this collector is used, the yield of Au crude gold ore is 26.44%, the grade of Au crude gold ore is 21.02g / t, and the recovery rate of Au is 82.96%.

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...
