Collecting agent for low-grade gold ores and method for manufacturing collecting agent

Abstract

The invention discloses a collecting agent for low-grade gold ores. The collecting agent comprises, by weight, 30-34 parts of diltiazem nitrile ester, 10-12 parts of alkyl xanthate acrylonitrile ester, 10-12 parts of ammonium dibutyl dithiophosphate, 1-2 parts of sodium hydroxide, 17-19 parts of styrene phosphoric acid, 3-4 parts of 4-butanediol vinyl ether, 1-2 parts of potassium dichromate, 2-3 parts of sodium metasilicate, 2-3 parts of diphenyl ethyl phenol-compounded polyoxyethylene ether, 1-2 parts of oleic acid polyoxyethylene ester, 5-7 parts of 2-peracetic acid-group butyric acid and 10-20 parts of activator. The collecting agent has the advantages that the collecting agent can realize capturing and foaming effects, foams are stable, and the collecting agent is high in collection capacity, so that the gold ores are high in recovery rate, selectivity and grade; owing to the activator, surface hydrophobic properties of the gold ores can be changed, internal structures of the gold ores can be activated, accordingly, the gold ore collection performance of the collecting agent can be improved, characteristics of the collecting agents can be played for the low-grade gold ores, the gold ores are high in recovery rate, and gold is high in grade.

Description

technical field [0001] The invention relates to the technical field of mineral flotation, in particular to a low-grade gold ore collector 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 pharmaceutic...

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
