preparation example Construction

[0013] The preparation method of the gold-containing pyrite gold collector is as follows: mix other components except the activator, stir at 48° C. at 10,000 rpm for 13 minutes, then add the activator, and stir at 7,000 rpm. Minutes under stirring for 25 minutes.

[0014] Experimental data

[0015] When flotation is performed on pyrite gold ore with an ore grade of 5.70g / t, when this collector is used, the Au crude gold ore yield is 22.35%, the Au crude gold ore grade is 20.98g / t, and the Au recovery rate is 82.26%.

Abstract

A collecting agent for separating gold from auriferous pyrite is prepared by the following raw materials in part by weight: 30-34 parts of xanthate, 12-14 parts of glycerin, 4-7 parts of sodium hexametaphosphate, 18-22 parts of terpenic oil, 10-12 parts of black powder, 2-3 parts of dimer acid, 1-2 parts of phthalic acid ester, 12-14 parts of diltiazem nitrile ester, 2-3 parts of 3-aminopropyltrimethoxysilane, 4-5 parts of nitrilotriacetic acid and 10-12 parts of activating agent. The collecting agent has a collecting function and a foaming function; foams are stable; the collecting ability is high, so that the recycling rate of the gold ores is high, the selectivity is high, and the grade of the gold ore is also high; and moreover, by using the collecting agent, the affinity of gold and iron can be reduced, collection on iron can be restrained, and then the grade of gold is improved. By using the activating agent, the surface hydrophobicity of the gold ore is changed, the internal structure is activated, and the gold collecting performance of the collecting agent is improved.

Description

technical field [0001] The invention relates to the technical field of mineral flotation, in particular to a gold collector for gold-bearing pyrite 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 ph...
