Embodiment 1

[0047] In 5-pentyl-1,2,4-triazole-3-thione at a concentration of 2 x 10 -5 mol / L, the pH of the pulp is around 8.5, the concentration of the blowing agent methyl isobutyl carbinol (MIBC) is 15mg / L, N 2 The gas flow rate is 200mL / min, and the chalcopyrite with a particle size of -0.076mm~+0.038mm is floated for 3 minutes. At this time, the flotation recovery rate of the chalcopyrite reaches 93.5%.

Embodiment 2

[0049] In 5-hexanol polyethylene (2) ether methyl-1,2,4-triazole-3-thione concentration is 2×10 -4 mol / L, the pH of the pulp is 8.0, the concentration of foaming agent MIBC is 15mg / L, N 2 The air flow rate is 200mL / min, and the malachite whose particle size is -0.076mm~+0.038mm is floated for 3 minutes. At this time, the flotation recovery rate of malachite is 98.7%.

Embodiment 3

[0051] A sulfide-oxidized copper ore sample in Dongchuan, Yunnan, the original ore contains 0.63% Cu, and its oxidation rate is 26.5%. Test process: one rough selection and one sweep. Grinding fineness: -0.074mm accounts for 90%; chemical conditions: roughing sodium sulfide 300 g / ton (pH 7.5 of pulp), sweeping sodium sulfide 800 g / ton (pH 8.0 of pulp), other chemical conditions And its results are shown in Table 1. The test results in Table 1 show that the 5-hydrocarbyl-1,2,4-triazole-3-thione collector achieved a higher copper recovery (sweeping concentrate) than butyl xanthate.

Abstract

The invention discloses a 1,2,4-triazole-3-thioketone type flotation collecting agent and application thereof. According to the application, a 1,2,4-triazole-3-thioketone type compound is used as the mineral flotation collecting agent which is applied to ore containing copper minerals, or silver minerals or gold minerals to recover valuable metal through flotation. Compared with common flotation collecting agents in the prior art, enrichment and recovery of copper minerals, or silver minerals or gold minerals can be effectively improved.

Description

technical field [0001] The invention belongs to the field of metal beneficiation, and in particular relates to the application of a 1,2,4-triazole-3-thione flotation collector. Background technique [0002] 1,2,4-triazole-3-thione compounds have the functions of sterilization, antibacterial, anticancer, anti-inflammation, regulating plant growth, and chelating metals. In the field of medicine, it can be used for anti-inflammatory, sedative, anti-anxiety, anti-spasm, anti-hypertensive, anti-bacterial, anti-cancer and diuretic; in the field of agriculture, it can be used for herbicides, insecticides and plant growth regulators; In the field, it is used as a rust remover and a metal corrosion inhibitor. [0003] The synthesis of 1,2,4-triazole-3-thiones is mainly prepared by cyclizing acylthiosemicarbazides by heating and refluxing in alkaline medium. Hoggarth refluxed aroyl thiosemicarbazide in sodium alkoxide ethanol solution, and then acidified to synthesize 5-substituted ...
