preparation example Construction

[0013] The preparation method of the refractory gold ore collector 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 carried out on carbonaceous silicate gold ore with raw ore grade of 3.60g / t, when this collector is used, the yield of Au crude gold ore is 14.61%, the grade of Au crude gold ore is 20.13g / t, and the recovery rate of Au is 81.72% %.

Abstract

A refractory gold ore collecting agent comprises, by weight, 23-27 parts of sodium butylxanthate, 3-4 parts of naphthalene sulfonic acid sodium salt, 4-6 parts of pyrophosphoric acid, 35-38 parts of oleic acid, 4-5 parts of sodium thiosulfate, 1-2 parts of sodium sulfide, 16-18 parts of isopropyl ethyl thionocarbamate, 4-6 parts of triethyl citrate, 6-8 parts of sodium ethylxanthate, 12-14 parts of mercaptobenzothiazole, 3-4 parts of gluconic acid and 10-12 parts of activator. The refractory gold ore collecting agent has collecting and foaming functions, stable foam and high collecting capability, so that gold ore recovery rate is high, selectively is good, and gold ore grade is high; through the activator, surface hydrophobicity of gold ore is changed, internal structure of the gold ore is activated, gold ore collecting performance of the collecting agent is improved, good recovery rate is guaranteed for various refractory gold ores, environmental pollution is low, and the collecting agent is easy to recover.

Description

technical field [0001] The invention relates to the technical field of mineral flotation, in particular to a refractory 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 pharmaceuti...
