Abstract

The invention relates to a fluorite beneficiation process. The beneficiation process is characterized by comprising the following steps of 1) calcium removal beneficiation of fluorite; 2) preparation of a fluorite floatation agent, wherein an intermediate produce crude fatty acid or mixed fatty acid produced by oleic acid is employed as a raw material, concentrated sulfuric acid in an amount which is 50 to 20 percent based on the weight of the fatty acid is added into the fatty acid to sulfate the fatty acid, and a beneficiation foaming agent in an amount which is 0.4 to 3 percent based on the weight of the fatty acid is added into a reaction product to obtain a product; 3) preparation of a composition of a fluorite floatation regulator, wherein any one of sulfuric acid, hydrochloric acid, nitric acid and acetic acid and corresponding salt are compounded with sodium silicate salt according to a proportion of the acid, the salt corresponding to the acid and the sodium silicate salt of (1-2.5):(1-5):(0.5-3); 4) fluorite floatation, a mixture consisting of acid, alkali and a synergist is employed as a regulator, oleic acid or rubber sodium oleate is employed as a collecting agent, and a process flow is a compound loop for fluorite floatation.

Description

technical field [0001] The invention relates to a processing technology, in particular to a fluorite beneficiation processing technology, which belongs to the technical field of mineral processing. Background technique [0002] Fluorite, also known as fluorspar, is the main source of fluorine in industry and one of the 20 important non-metallic mineral raw materials in the world. It is widely used in metallurgy, aluminum smelting, glass, ceramics, cement, and chemical industries. [0003] Like other minerals, fluorite minerals are generally mined in two ways: open-pit and underground. The shallow part of the ore body is dominated by open-pit mining. Drill rocks manually with steel drill hammers, and transport ore and slag manually. A few use mechanical rock drilling and mechanical transportation. Open-pit mining has low cost, simple equipment and good economic benefits. At present, most township enterprises and mass mining basically adopt this method. The development o...
