specific Embodiment approach 1

[0047] Using molybdenum concentrate as raw material, industrial molybdenum disulfide is directly produced through physical flotation, and molybdenum tailings are obtained. The molybdenum disulfide content in the raw material is 66.7~83.4% (the molybdenum content is 40~50%). Before the flotation operation starts The corresponding parameters in the sorting operation are preset through the man-machine interface of the automatic control system. The parameters that can be set include the opening of the slurry valve for rough selection, three-time selection, three-time sweeping, and flotation agents such as water glass. The amount of dosing in each sorting operation, etc., its flotation operation includes the following steps:

[0048] The first step is to mix the raw materials, water and molybdenum concentrate raw materials are mixed and stirred to make a mixed slurry,

[0049] In the second step, a section of fine grinding, the mixed slurry is sent to the vertical stirring mill I f...

Abstract

The invention relates to the technical field of mineral flotation separation, in particular to a method for physically producing industrial molybdenum disulfide. The proposed method for producing industrial molybdenum disulfide by physical method uses molybdenum concentrate as raw material to directly produce industrial molybdenum disulfide through physical flotation. Steps of fine grinding, three-time selection, three-time sweeping and product dehydration; the automatic control system is used to automatically adjust the slurry delivery volume and the flotation reagent dosage; and the process water is treated for reuse. The invention uses molybdenum concentrate as raw material, directly produces industrial molybdenum disulfide through physical flotation, and obtains molybdenum tailings, reduces the dosage of chemicals, does not need special heating and heat preservation means, and has low production cost; the production process is fine and controllable, which is beneficial to quality control ; Utilize process water backwater, realize zero discharge of waste water, reduce the amount of chemicals used, improve the recovery rate of molybdenum, and be beneficial to environmental protection.

Description

technical field [0001] The invention relates to the technical field of mineral flotation separation, in particular to a method for physically producing industrial molybdenum disulfide. Background technique [0002] Molybdenum disulfide has a hexagonal layered structure, is a good solid lubricant, and is a poor conductor and non-magnetic material. It can be used at temperatures from -60°C to 400°C, and has strong corrosion resistance, compression resistance, high vacuum resistance, radiation resistance and adhesion to metals. Molybdenum disulfide is widely used in military field, automobile industry, mechanical processing, aerospace, petrochemical industry, lithium ion battery, composite materials, coatings, sealing materials, etc. Molybdenum disulfide is also a good next-generation semiconductor material. It has broad development prospects in the manufacture of ultra-small transistors, light-emitting diodes and solar cells. [0003] Among the natural minerals, molybdenum h...
