Many chemical beneficiation methods of manganese have been extensively researched in China. Promising tests have been conducted on two methods: kraft black manganese law and bacterial leaching of manganese.
Calcium Fluorite Beneficiation Process
This process involves a rough selection and multiple selections of work composed of oleic acid or its substitutes as a collector for roughing. A mixture of sulfuric acid and acidic water glass in a ratio of 1:0.5 to 1:2 is used as a calcium silicate mineral inhibitor. The joint amount used is 0.5~1.5 kg/t ore. This process has the advantage of adding calcium, high efficiency, simple technology, and low cost, and can obtain low-grade fluorite concentrate from calcium carbonate-type fluorite mineral content.
Natural Fluorite Optical Coating Process
This process involves dressing, crushing, preparation, mixing, and sintering. The invention process is simple, low-cost, and meets a variety of arts and crafts with paint and fluorescent effect.
Preparation Method of Fluorite Flotation
This process involves the production of intermediate products of oleic acid or mixed fatty acids of crude fatty acids as raw materials. Adding 3% to 15% sulfuric acid to its weight as fatty acids and making it react using sulfuric acid technology. Further reaction products of fatty acids by adding 0.4% to 3% of foaming agent is needed for mineral products. This process provides a low-cost method of production with a strong, water-soluble, well-dispersed, suitable at room temperature and low-temperature flotation fluorite.
Fluorite Flotation Agent Composition Adjustment
This process involves a flotation method of fluorite mine where acid jacketed plus synergist agent is used to adjust the flotation. The invention is adding acid and water glass with the acid composition of one or more of a mixture of soluble salts for regulating the composition and form a composition series. The range of the salt water glass composition is 12:15:0.5 to 1. This process has good adaptability, stability, concentrate quality, high recovery rate, and low cost.
Carbonate – Flotation Separation of Fluorite Mine
This process provides a cost-effective method of flotation separation, especially for high carbonate content of the flotation separation of fluorite mine. The key is to choose an effective inhibitor of carbonate minerals – acidified water glass and Canadian drug measures in the conventional process conditions, to achieve high purity carbonate and fluorite separation.
Fluorite Flotation Method with Modifier
This invention relates to flotation with a modifier method of fluorite. The process uses acid, alkali, and synergist mixture composed as the regulator. Oleic acid or sodium oleate is used as a rubber collector, and the process is carried out in the near-neutral and fluorite under normal temperature conditions. Fluorite concentrate obtained has a high recovery rate, low heteroatom product quality, low consumption of Pharmacy, low cost, and is suitable for all kinds of fluorspar concentrator applications.
