Talc ore beneficiation method and talc ore beneficiation device

Abstract

The invention provides a talc ore beneficiation method. The talc ore beneficiation method is characterized in that by utilizing difference of friction coefficients between talc ores and a steel plate and between gangues and the steel plate and different hydrophilic properties of the talc ores and the gangues, and by means of combination of water flow and mechanical rotation, the purpose that the talc ores are effectively separated from the gangues is achieved. The invention further discloses a talc ore beneficiation device which is provided with water flow and based on the talc ore beneficiation method. The talc ore beneficiation device comprises a large horizontal steel rotary drum, the large rotary drum support seat, a separating scrapping plate, a feed port, a talc ore discharge port, a gangue discharge port and more than one power unit, wherein the power units are used for driving the large rotary drum and the separating scrapping plate to rotate. The talc ore beneficiation method and the talc ore beneficiation device have the advantages that beneficiation efficiency and separation precision of the talc ores are improved, dust is reduced, the risk that operating staff suffer from silicosis is lowered, noise is lowered, the working environment of the operating staff is improved, mechanical abrasion between the separating scrapping plate and the large rotary drum is reduced, and the service life of the device is prolonged.

Description

technical field [0001] The invention belongs to the technical field of beneficiation methods, and in particular relates to a talc ore beneficiation method and device. Background technique [0002] Talc is hydrated magnesium silicate with the molecular formula Mg 3 (Si 4 o 10 )(OH) 2 , extremely soft, lubricating, hydrophobic, chemically inert, and widely used in industry. Since talcum powder is mostly used in industry, its production process must go through multiple processes such as mining, mineral processing, and crushing. [0003] The existing methods of talc beneficiation are mainly divided into: hand separation, optical separation, flotation and magnetic separation. Optical separation is to use ultraviolet light irradiation, talc emits white fluorescence under ultraviolet light, gangue does not emit fluorescence; flotation is to use the characteristics of talc being lipophilic and gangue hydrophilic; magnetic separation is mainly to remove ferromagnetic gangue.

Problems solved by technology

Although the performance of this talc and miscellaneous stone separator is greatly improved compared with the aforementioned talc sorting device, it still has the problems of large dust and high noise during operation, and the scraper also has a large wear on the inner wall of the large drum. There is still room for improvement in its sorting accuracy and sorting efficiency.
