Problems solved by technology

The process of molybdenum suppression and floating copper is complicated to operate, the cost is high, and the recovery rate of molybdenum is not high; the process of suppressing copper and floating molybdenum is widely used
Whether this process can realize the separation of molybdenum and non-molybdenum metal sulfide ores depends on the selection of inhibitors. It is often necessary to use a large amount of cyanide, Knox and sodium sulfide as inhibitors, which is highly toxic and pollutes the environment. , Foam is difficult to control and the dosage of medicine is large, etc.

Embodiment 1

[0033] Take 1 g of molybdenite and chalcopyrite single minerals of 38-74 μm respectively and mix them uniformly at a ratio of 1:1, add 50 mL of distilled water into a 70 mL hanging tank flotation machine, and stir and adjust the slurry at 1300 r / min. Let the pulp be fully dispersed, adjust the pH to 10 after adding the inhibitor, stir for 5 min, add kerosene and stir for 2 minutes, add foaming agent A200 and stir for 1 min, the inhibitor (R 1 is thiol, R 2 The concentration of amine group is 400mg / L, the concentration of collector is 20mg / L, and the concentration of foaming agent is 20mg / L. After the stirring is completed, aeration flotation is performed to obtain foam products and tailings. Dry the foam product and tailings separately, weigh and test the molybdenum and copper content in the concentrate, and calculate the recovery rate of molybdenum and copper in the concentrate. It is calculated that the floating rate of molybdenite is 90%, and the floating rate of chalcopy...

Embodiment 2

[0035] Take 1g of molybdenite and pyrite single minerals of 38-74μm and mix them uniformly at a ratio of 1:1, add 50mL of distilled water to a 70mL hanging tank flotation machine, and stir and adjust the slurry at 1300r / min. Let the pulp be fully dispersed, adjust the pH to 9 after adding the inhibitor, stir for 5 minutes, add diesel oil and stir for 2 minutes, add the foaming agent BK-401 and stir for 1 minute, the inhibitor (R 1 is amino, R 2 The concentration of sulfhydryl group is 200mg / L, the concentration of collector is 20mg / L, and the concentration of foaming agent is 20mg / L. After the stirring is completed, aeration flotation is performed to obtain foam products and tailings. Dry the foam product and tailings separately, weigh and test the molybdenum and iron content in the concentrate, and calculate the recovery rate of molybdenum and iron in the concentrate. It is calculated that the floating rate of molybdenite is 94.8%, and the floating rate of the pyrite is 5%....

Embodiment 3

[0037] Take 1g of molybdenite and galena single minerals of 38-74μm and mix them uniformly at a ratio of 1:1, add 50mL of distilled water to a 70mL hanging tank flotation machine, and stir and adjust the slurry at a speed of 1300r / min. Let the pulp be fully dispersed, adjust the pH to 10 after adding the inhibitor, stir for 5 minutes, add kerosene and stir for 2 minutes, add the foaming agent and stir for 1 minute, the inhibitor (R 1 Amino, R 2 is mercapto group, ) concentration is 400mg / L, collector concentration is 20mg / L, foaming agent concentration is 20mg / L, and described foaming agent is MIBC, A200, BK-401 mixed according to mass ratio 31:22:47 the mixture after. After the stirring is completed, aeration flotation is performed to obtain foam products and tailings. Dry the foam product and tailings separately, weigh and test the molybdenum and lead content in the concentrate, and calculate the recovery rate of molybdenum and lead in the concentrate. It is calculated th...

Abstract

The present invention relates to a copper-molybdenum separation inhibitor and its use and usage method. The inhibitor contains 50% to 100% of small triazole molecules, and the general structural formula of the small triazole molecules is as shown in Formula I. indicated that the R 1 and R 2 At least one of them is amino, the R 1 When it is amino, the R 2 Any one selected from H, amino, mercapto, carboxyl, and hydroxyl, the R 2 When it is amino, the R 1 Any one selected from H, amino group, mercapto group, carboxyl group, and hydroxyl group. The copper-molybdenum separation inhibitor according to the present invention can be applied to the flotation separation of mixed concentrates such as copper-molybdenum, lead-molybdenum, zinc-molybdenum, and sulfur-molybdenum, or the flotation separation of copper, lead, zinc, sulfur, and molybdenum polymetallic sulfide ores, to achieve brilliance Efficient flotation separation of molybdenum ore and other metal sulfide ores.

Description

technical field [0001] The invention belongs to the technical field of mineral separation and beneficiation, and in particular relates to a copper-molybdenum separation inhibitor and its application and application method. Background technique [0002] Molybdenum is an important rare metal and strategic reserve resource, the average content of which is only 1 / 100,000 in the earth's crust. Molybdenite is the main source of molybdenum extraction. Most of molybdenite is symbiotic with sulfide minerals, especially copper sulfide ore symbiosis. According to statistics, nearly 75% of copper and 50% of molybdenum in the world are produced from copper-molybdenum ore. Taking copper and molybdenum as an example, there are currently two flotation separation processes for copper-molybdenum flotation mixed concentrate: one is copper suppression and molybdenum floating; the other is molybdenum suppression and floating copper. The process of suppressing molybdenum and floating copper is ...
