Embodiment 1

[0024] In 3-hexyl-4-amino-1,2,4-triazole-5-thione at a concentration of 5×10 -5 mol / L, the pH of the pulp is 7.3, the concentration of the foaming 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 97.9%.

Embodiment 2

[0026] In 3-hexyl-4-amino-1,2,4-triazole-5-thione at a concentration of 3×10 -4 mol / L, the pH of the pulp is 8.2, the concentration of foaming agent MIBC is 15mg / L, N 2 The air flow rate is 200mL / min, and the malachite with a particle size of -0.076mm~+0.038mm is floated for 3 minutes. At this time, the flotation recovery rate of the malachite is 99.5%.

Embodiment 3

[0028] An oxidation-copper sulfide ore sample in Xinjiang, the original ore contains 0.91% Cu, of which the content of copper oxide is 0.52%, and the content of copper sulfide is 0.39%. Test process: one rough selection and one sweep. Grinding fineness: -0.074mm80%; chemical conditions: roughing sodium sulfide 1200 g / ton, sweeping sodium sulfide 200 g / ton, other chemical conditions and results are shown in Table 1. The test results in Table 1 show that the 3-alkyl-4-amino-1,2,4-triazole-5-thione collector has obtained more than xanthate, octyl hydroxamic acid and xanthate + Higher copper recovery and copper grade (coarse concentrate) with hydroxamic acid.

Abstract

The invention discloses application of amino triazolethione collecting agents. The application includes that amino triazolethione compounds are used as mineral flotation collecting agents which are applied to recycling valuable metal from ores with copper, silver or gold mineral by means of flotation. Compared with the prior art, the application has the advantage that the copper, silver or gold mineral enrichment and recycling capacity can be effectively improved by the aid of the amino triazolethione collecting agents as compared with commonly used flotation collecting agents in the prior art.

Description

technical field [0001] The invention relates to the application of an aminotriazolethione collector and belongs to the field of metal beneficiation. Background technique [0002] Aminotriazolethione compounds and their derivatives have good properties of sterilization, antibacterial, regulation of plant growth, and metal chelation. In the field of biomedicine, such compounds are used for anti-inflammatory, sedative, anti-anxiety, anti-microbial, and anti-fungal; in the field of agriculture, they are used as high-efficiency and low-toxicity herbicides, insecticides and plant growth regulators; Used as metal corrosion inhibitor. [0003] Jack and Ned used potassium 3-amide dithiocarbamate as a raw material to study three synthetic methods of aminotriazolethiones (Jack R. Reid, Ned D. Heindel. Improved syntheses of 5-substituted-4- amino-3-mercapto-(4H)-1,2,4-triazoles [J]. Heterocyclic Chem, 13, 925 (1976)). Beyer and Kroger prepare alkyl triazole thione (Beyer H., Kroger, ...
