preparation example Construction

[0013] The preparation method of the collector for gold beneficiation of the high-arsenic gold ore is to mix other ingredients except the active agent, stir for 18 minutes at 47°C and 11000 rpm, and then add the active agent, Stir at rpm for 25 minutes.

[0014] Experimental data

[0015] When flotation is performed on high-arsenic gold ore with a raw ore grade of 4.60g / t, when the collector is used, the Au crude gold ore yield is 18.07%, the Au crude gold ore grade is 20.71g / t, and the Au recovery rate is 81.36%.

Abstract

A collecting agent for separating gold from high-arsenic type gold ores is prepared by the following raw materials in part by weight: 2-3 parts of sodium sulfite, 1-2 parts of calcium oxide, 22-24 parts of alkyl xanthate acrylic nitrile ester, 2-3 parts of sodium carbonate, 3-4 parts of sodium pyrosulfite, 1-2 parts of sodium sulphide, 34-38 parts of xanthate, 2-3 parts of glycerin polyethenoxy ether propylene ether fatty acid ester, 14-16 parts of butylamine aerofloat, 12-14 parts of terpenic oil, 3-4 parts of ammonium citrate and 10-12 parts of activating agent. The collecting agent has a restraining effect on arsenic in the high-arsenic type gold ores, and is high in gold collecting ability; secondary environmental pollution is avoided; complex pre-treatment work procedures are not required; the process is simple; and the recycling cost is low. Moreover, by using the activating agent, the surface hydrophobicity of the gold ores 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 collector for gold beneficiation of high-arsenic gold ore and a preparation method thereof. Background technique [0002] In addition to leaching, most concentrators still choose the flotation method to recover gold minerals. At present, the collectors that have a good collection effect on gold minerals include aniline black medicine, butyl ammonium black medicine, gold catcher, Y-89, M16, QF and other flotation reagents, and conventional flotation reagents collect gold ore. The ability is strong, but the selectivity is poor, the gold recovery rate is low, the index fluctuates greatly, the flotation effect is not ideal, and the resource utilization rate is low. [0003] In recent years, great progress has been made in the research and application of new and high-efficiency combination flotation reagents to improve gold beneficiation indexes. In the research and application...
