Zhongang Mining: Fluorite Flotation Process
2022-04-23 16:39:00 【Information fast lane】
Fluorite, also known as fluorite , Its main chemical composition is calcium fluoride , Its crystal form is mainly cubic , Equiaxed system . As a non-metallic raw material, fluorite plays a more and more important role in the development of China's industry , In cement 、 glass 、 ceramics 、 metallurgy , Cast stone and other industrial fields have a wide range of industrial applications . China is rich in fluorite resources , Its reserves are second only to South Africa and Mexico , Third in the world , But the per capita share is less than the world average . With the development and progress of science and Technology , In recent years, fluorine chemical industry has developed rapidly , The proportion of fluorite used in the manufacture of hydrofluoric acid and its derivatives has gradually increased , Hydrofluoric acid is widely used in aerospace industry , Atomic energy industry , Petrochemical Industry and pharmaceutical industry ; It can also be used for some high-tech raw materials . therefore , Fluorite is more widely used and important , And has become an important strategic resource for national economic construction .
In the market expansion, the demand and quality of fluorite are also higher and higher , Therefore, vigorously developing fluorite flotation technology has become a resource development strategy . In production practice , The main beneficiation methods of fluorite ore are manual beneficiation 、 Gravity separation and flotation . among , Hand selection is often used as an aid , Gravity separation method is applicable to the production of metallurgical grade lump ore or as the pre concentration operation of fluorite flotation process . In view of the dilution of fluorite raw ore 、 Fluorite and gangue are embedded in each other , Flotation is the main beneficiation method for separating fluorite and gangue minerals at present , How to improve the effect of fluorite flotation has also become a widely concerned problem . We can from grinding fineness 、 Pulp temperature 、 Flotation reagent 、 Pulp level 、 pulp pH value 、 Water quality and flotation process , By improving the above factors, the flotation and beneficiation effect of fluorite can be improved .
Fluorite (CaF) contain F48.9%,Ca51.1% Fluorite has good floatability , Use fatty acids as collectors . Pulp PH The value has a great influence on the flotation effect of fluorite . Use oleic acid as collector , When pulp PH by 8~11 when , Fluorite has good floatability . secondly , Raise the temperature of the pulp , It can also improve the flotation index of fluorite . meanwhile , Fluorite with different particle sizes , Their flotation behavior is also different , The flotation of coarse-grained Dongshi is characterized by strong selectivity ; Therefore, its concentrate grade is high , But the recovery rate is low ; The flotation result of medium size fluorite is that the concentrate grade and yield are high ; The concentrate grade and recovery of fine Putian flotation are low . When the flotation belt stone uses oleic acid as collector , There are also high requirements for flotation water , That is, when the water quality is hard water , First, soften the water entering the flotation process in advance .
Zhongang mining is an investment company mainly engaged in Fluorite Mining and fluorite industrial chain 、 production 、 machining 、 Technology development, etc ; Fluorite ( Ordinary ) Underground mining ( Including concentrator , Limited to subsidiaries ); Mining of mineral products 、 machining 、 testing 、 Mining enterprises engaged in technical consultation on mine environment and safety . The company's professional team has more than 20 years of mine exploration 、 Experience in mining and ore flotation . Smelting qualified fluorite concentrate for the market , Have certain technology and experience .
