Embodiment 1

[0051] see figure 1 As shown, the present embodiment provides a kind of high-efficiency flotation method of talc-containing molybdenum ore, molybdenum raw ore contains Mo 0.14%, talc 16%, S 0.64%, Fe 10.56%, SiO 2 46.82%.

[0052] Specific steps are as follows:

[0053] S1. Grinding and classification: The raw ore in the mining area is crushed in three stages to below 12mm, and then the crushed ore is fed into a ball mill for grinding. The grinding products are classified by a cyclone to obtain 82% of the fineness below 0.074mm. % cyclone classification overflow product, the hydrocyclone classification overflow slurry adjustment to a concentration of 30% to 35%, fed into the flotation talc removal operation.

[0054] S2. Talc removal: Since the talc content is higher than 15%, the graded overflow of the cyclone is fed into the strong mixing tank, and methyl isobutyl carbinol (MIBC) is added in the strong mixing tank as a talc collector. The amount is 12 grams / ton of raw or...

Abstract

The invention provides a talc inhibitor and a high-efficiency flotation method for talc-containing molybdenum ore. Talc inhibitors include sulfates, polysaccharides, aluminum salts and dehydrogenases, which can achieve efficient separation of talc and molybdenum ore. The method adopts a pre-removal of talc-molybdenum flotation process, and sequentially performs grinding and classification, flotation to remove talc, molybdenum roughing and molybdenum concentration to obtain molybdenum concentrate. In the process of molybdenum roughing and molybdenum concentration, the invention effectively solves the problem that talc interferes with molybdenum mineral flotation, resulting in low recovery rate and grade of molybdenum concentrate, and the tailings water can be directly returned to the mill The mine process effectively solves the problem that tailings water cannot be directly reused in the pre-removal of talc-molybdenum flotation process. While improving the grade of the molybdenum concentrate, the invention also increases the recovery rate of the molybdenum concentrate by 15-25 percentage points, thereby improving the utilization rate of the molybdenum ore resource.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a talc inhibitor and a high-efficiency flotation method for molybdenum ore containing talc. Background technique [0002] When talc exists in flotation, there will be two effects. One is that talc has good buoyancy, sometimes even better than the target mineral, which makes it difficult to suppress talc, and it is easy to enter the concentrate product with the foam. Reduce the beneficiation index. Second, talc is soft, easy to muddy in the crushing process, easy to produce mud cover with useful minerals, adhere to the surface of the air bubbles of the target minerals, difficult to separate, and also cause sticky foam, poor selectivity, and worsen flotation environment, resulting in increased dosage of flotation reagents and poor concentrate quality. [0003] For the beneficiation of molybdenum ore with high talc content, the existing technologies are generally floata...
