Fluorspar as a strategic mineral, plays a very important role in the economic construction of the country. Fluorite plays such an important and irreplaceable role in China's economic construction, what is the process of fluorite ore dressing? In this paper, Red Star Machine provides you with six different fluorite ore dressing process for reference use.
1, Fluorite de-calcium beneficiation process
A fluorite calcium removal beneficiation process, consisting of a roughing, multiple selection operations, with oleic acid or its substitutes as a collector for roughing, a mixture of sulfuric acid and acidic water glass as a calcium mineral inhibitor, the ratio of sulfuric acid and acidic water glass is 1:0.5-1:2, the joint dosage of 0.5-1.5kg / t of raw ore. This process has the advantages of high calcium removal efficiency, simple process, low cost, and can select special grade fluorite concentrate with low calcium carbonate content from high calcium fluorite ore.
2、 Fluorescent coating of natural fluorite
A processing process of natural fluorite light coating, the process is ore dressing - crushing - preparation - mixing - sintering. The process is characterized by simple technology and low cost, which can meet the needs of paints for arts and crafts and various articles with fluorescent effect requirements.
3, A preparation method of fluorite flotation agent
A preparation method for the preparation of fluorite flotation capture agent, oleic acid production of intermediate products of crude fatty acids or mixed fatty acids as raw materials, to which is added to the weight of fatty acids weight 3% ~ 15% of concentrated sulfuric acid, so that the sulfuric acid reaction occurs, and then to the reaction of the product into the weight of fatty acids weight of 0.4% ~ 3% of the ore dressing foaming agent that is a product. The method provided by the present invention has low production cost, and the fluorite flotation selective capture agent produced has strong capture ability, good water solubility and dispersion, and is suitable for fluorite flotation at room temperature and low temperature.
4. Fluorite flotation adjuster compositions
A process method for flotation of fluorite ore, prior art flotation of fluorite ore using acid plus set plus synergist as adjusting agent. The process is water glass plus acid and the acid composed of one or more soluble salts mixed into the combination as a regulator, and the formation of a series of combinations, can be used in sulfuric acid, hydrochloric acid, nitric acid, oxalic acid, acetic acid in any one of the acids and the corresponding salts, the combination of the proportion of the range of water glass, acid, salt = 1 ~ 2 ∶ 1 ∶ 5 ∶ 0.5 ～ 1. The process is highly adaptive, stable, high quality concentrates, high recovery rate, low cost. The process is adaptable, stable, with high quality concentrate, high recovery and low cost.
5, Carbonate-fluorite ore flotation separation method
This is a kind of carbonate; fluorite ore economic and effective flotation separation method, especially suitable for high carbonate content of fluorite ore flotation separation. The key lies in the selection of effective inhibitors of carbonate minerals, acidified water glass and dosing measures, in the conventional process conditions, so that carbonic acid and fluorite to achieve high-purity sorting.
6、Fluorspar flotation method
The process relates to a method of flotation of fluorite ore with an adjusting agent. The present invention adopts a mixture of acid, alkali and synergist as adjusting agent, oleic acid or sodium oleate as trapping agent, the process is a composite circuit, the flotation of fluorite ore is carried out under nearly neutral and room temperature conditions, and the fluorite concentrate obtained has high recovery rate, good product quality with low impurity, low consumption of chemicals and low cost, which is suitable for application in all kinds of fluorite beneficiation plants.
