The introduction of Fluorite Ore Processing :
Fluorite, also known as fluorspar, is a major source of industrial fluoride elements, 20 kinds of the world, one of the important non-metallic mineral raw materials, fluorite is widely used in the metallurgy of aluminum, glass, ceramic, cement chemical industry. The pure colorless transparent fluorite as an optical material, bright color can also be used as a gem stone, and arts and crafts carving raw fluorite.
Fluorite is the basic raw material of fluorine chemical industry, its products are widely used in the field of aerospace, aviation, refrigeration, pharmaceuticals, pesticides, anti-corrosion, fire-fighting, electronics, electrical, mechanical and nuclear, with the continuous development of science and technology and the national economy,the fluorite has become a modern industrial mineral raw materials, many developed countries as an important strategic material reserves.
Fluorite ore mineral processing methods:
1. Fluorite ore processing
Fluorite ore processing methods which is one roughing repeatedly choice,as a collector agent rougher with oleic acid or its substitutes, to a mixture of sulfuric acid with an acidic waterglass-containing substanceinhibitor, a sulfuric acid with an acidic waterglass ratio is 1:0.5 to 1:2, the joint used in an amount of 0.5 ~ 1.5kg / t ore. The present invention provides fluorspar addition to calcium beneficiation process has in addition to the high efficiency of calcium, the process is simple, low-cost advantages can be selected from the high calcium fluorite ore grade fluorite concentrate with a low content of calcium carbonate.
2.Natural fluorite fluorescent paint
A natural fluorite fluorescent paint process, the process of dressing - crushed - preparation - mixing - sintering.The present invention has a simple process and low cost to meet the arts and crafts paint and various fluorescent effect required items need.
3.The preparation method of fluorite flotation agent
A process for the preparation of fluorspar flotation method, the crude intermediate product produced with oleic fatty acids or mixed fatty acids as raw materials, added thereto weight of the fatty acids of 3% to 15% by weight of concentrated sulfuric acid, so that the occurrence of sulfatedreaction, again in the reaction product by weight of fatty acid weight the beneficiation of 0.4% to 3% of foaming agent accompli product. The present invention provides a method of producing low-cost production fluorite floating selection collectors collecting capacity, water-soluble, dispersible, suitable for room temperature and low flotation fluorite.
4. Fluorite flotation adjusting agent composition
A flotation of fluorite ore processing method, it is granted a patent improvements 87,105,202 No.Flotation fluorite mineral acid jacketed plus synergist modifier. Any one of the water glass of the present invention, the addition of acid and the acid composition of one or more soluble salt mixture composition for the adjusting agent, and the formation of the composition series, can be used sulfuric acid, hydrochloric acid, nitric acid, oxalic acid, acetic acid kinds of acids and the corresponding salts, the combination ratio range of waterglass and acid · salt = 1 to 2:1 to 5:0.5 to 1. The present invention is adaptable, good stability, high quality concentrate, high recovery, low cost.
5.Carbonate - fluorite flotation separation method
The present invention provides a carbonate - fluorite ore economic effective flotation separation method, especially for the high carbonate content of the flotation separation of fluorite ore. The key is to choose the carbonate minerals inhibitors - acidified water glass processing drug measures in the conventional process conditions, carbonate and fluorite achieve high purity sorting.
6.Flotation fluorite ore processing
The present invention uses a mixture of acid, alkali and synergist as a modifier, oleic acid or oak sodium oleate as collector, the process for the composite circuit in a near-neutral under normal temperature conditions fluorite oreflotation of fluorite concentrate obtained a high recovery rate, product quality, low impurity, pharmaceutical consumption, low cost, suitable for all kinds of fluorspar concentrator applications.
