Problems solved by technology

However, the technical solution disclosed in this invention does not fully consider the influence of foam viscosity on the flotation process. When the foam viscosity is too high, it will make the pumice gangue and molybdenite bond, and it will be easier to bring the pumice gangue into the flotation process. Mineralizes the froth layer, reducing the selectivity of the flotation process

Abstract

The invention discloses a molybdenite beneficiation inhibitor and a preparation method thereof. A molybdenite beneficiation inhibitor is mainly composed of components A and B, and the weight ratio of component A to component B is 1:1-1:2.5; wherein the components in component A and the parts by weight of each component are as follows : 80-95 parts of sodium silicate, 5-20 parts of gum gum, the components in B component and the weight parts of each component are as follows, 50-80 parts of aluminum sulfate, 5-10 parts of potassium aluminum sulfate dodecahydrate, carboxylate 15-30 parts of sodium methylcellulose, 5-15 parts of tannin extract, and 10-25 parts of dextrin. A and B components are co-dissolved in water to prepare an aqueous solution with a weight fraction of 5-15%, and then the aqueous solution is fully stirred and homogenized to obtain a molybdenite beneficiation inhibitor. By organically combining various components, a water film can be formed on the gangue in molybdenite, which avoids hydrophobic foaming, and in addition, reduces the viscosity of pulp and foam, and reduces or blocks the interaction between the gangue and the collector. Adsorption, thus solving the problem of sticky pulp foam in the beneficiation process and improving the collection efficiency of the collector.

Description

technical field [0001] The invention belongs to the technical field of mineral processing inhibitors, and in particular relates to a molybdenite mineral processing inhibitor and a preparation method thereof. Background technique [0002] Molybdenite (MoS 2 ) is an important output mineral of molybdenum resource industrial products. However, molybdenite often contains gangue, and there are many kinds of gangue. The common ones are mica, calcite, talc, chlorite, graphite, etc. The main component of mica is SiO 2 、K 2 O, Al 2 o 3 , the main component of calcite is CaCO 3 , the main components of talc are MgO, Al 2 o 3 , the main component of chlorite is aluminosilicate. [0003] The molybdenite crystal has a hexagonal layered or plate-like structure, and the interlayers are combined by the Van der Waals force between S-Mo-S, and the bonding force is weak. Molybdenite has good natural buoyancy, so molybdenite is usually beneficiated by flotation. The molybdenite flotat...
