Embodiment 1

[0085] Raw ore: Tugurige Gold Mine located in Bayannaoer City, Inner Mongolia, is a large quartz vein deposit. There are two types of ore in the deposit: gold-bearing quartz vein-type ore and gold-bearing altered rock-type ore. The main gold-bearing minerals are It is natural gold and tellurite, which is associated with pyrite, galena, limonite, hematite and quartz; non-metallic minerals are quartz, feldspar, a small amount of chlorite and calcite; the Au grade in the ore is 1.2 ~6g / t, the average Au grade is 4.2g / t;

[0086] Main collector: the mass ratio of xanthate, black medicine, fatty acid salt and mercaptan salt is 50:25:20:5, among which, xanthate is ethyl xanthate, butyl xanthate and Y89 xanthate according to the mass ratio 5:90:5 mixture, the black medicine is a mixture of butyl ammonium black medicine and No. 31 black medicine according to the mass ratio of 90:10, the fatty acid salt is oxidized paraffin wax soap, and the mercaptan salt is di-n-butyl-2- Mercapto-et...

Embodiment 2

[0110] The mass ratio of xanthate, black powder and fatty acid salt in the main collector is 60:35:5, and the rest of the technical means are the same as in Example 1 to obtain gold concentrate and tailings.

Embodiment 3

[0122] The mass ratio of xanthate, black powder, fatty acid salt and mercaptan salt in the main collector is 45:35:15:5, and other technical means are the same as in Example 1 to obtain gold concentrate and tailings.

Abstract

The invention belongs to the technical field of flotation, in particular to a gold ore composite collector and its application. The gold ore composite collector provided by the present invention includes an independently packaged main collector and an auxiliary collector; the main collector includes xanthate, black drug and fatty acid salt; the auxiliary collector includes Diisooctanoic acid thioether, RA935 and sodium linoleate. In the present invention, the main collector has different selectivity and collection ability to gold-containing sulfides, synergistic cooperation is conducive to improving the selective collection effect of gold-containing sulfides, and fatty acid salts are beneficial to improving gold-containing sulfides such as hematite. The collection effect of oxides, the main collector is a colloid bundle of active functional groups of xanthate, black powder and fatty acid salt, which is beneficial to realize the collection of sulfide and altered pyrite in quartz vein-altered rock type gold deposits. The joint adsorption of minerals and oxides improves the effect of oxygen-sulfur flotation; the auxiliary collector further improves the collection effect of gold minerals and gold-containing oxides in quartz vein-altered rock type gold deposits through synergistic effect.

Description

technical field [0001] The invention belongs to the technical field of flotation, in particular to a gold ore composite collector and its application. Background technique [0002] Quartz vein type gold deposit refers to a type of deposit formed by metasomatism and precipitation of hot water solution in vein shape. The main useful minerals in the ore are natural gold and a small amount of tellurite. The main metal minerals include pyrite, Chalcopyrite and galena, minor metallic minerals include antimony tetrahedrite, stibnite, sphalerite and azurite; major non-metallic minerals include quartz, feldspar, a small amount of chlorite and calcite. The embedded particle size of natural gold in the ore ranges from 0.2 to 300 μm. Except for a small amount of natural gold particles which are relatively coarse, the embedded particle size of most gold minerals is fine, and most of them are embedded in pyrite and galena in a dispersed form. , quartz, limonite or hematite and other mine...
