Problems solved by technology

[0003] The ore selected by a company is high talc type molybdenum ore, and its tailings enter the tailings dam after iron selection. Since the company also floats scheelite in addition to iron selection, a large amount of fatty acid is added to the scheelite flotation process. In order to reduce the interference factors in the subsequent flotation process, there is an urgent need for a method that can directly carry out flotation without desliming in advance

Abstract

The invention relates to a desliming method for high-argillization high-talc ore. According to the desliming method, desliming structures are arranged in a hydrocyclone and a stirring barrel, flotation operation can be directly conducted on raw ore pulp, the desliming process is completed in the flotation process, that is, the desliming process is synchronously completed in the modified stirring barrel and the hydrocyclone, pre-desliming does not need to be conducted, the whole flotation process is simplified, production efficiency can be improved, the desliming product can be subjected to magnet recovery, and talc of the desliming product can also be used for manufacturing of building materials or the paint industry.

Description

Technical field: [0001] The invention belongs to the technical field of mineral processing, and mainly relates to a desliming method of high-mud high-talc ore. Background technique: [0002] It is known that desliming is a process of separating the fine slime and coarse sand in the ore slurry during the beneficiation operation. Ore slime is a disturbing factor in any beneficiation process, which directly affects the separation index and the consumption of beneficiation agents. Therefore, desliming operation is a key preparatory operation for mineral beneficiation methods such as gravity separation, magnetic separation and flotation. . [0003] The ore selected by a company is high talc type molybdenum ore, and its tailings enter the tailings dam after iron selection. Since the company also floats scheelite in addition to iron selection, a large amount of fatty acid is added to the scheelite flotation process. In order to reduce the interference factors in the subsequent fl...
