Natural fluorite ore processing

Natural fluorite ore process:

1. Calcium fluorite demineralization process A fluorite demineralization process consisting of one rough selection and multiple selection operations, using oleic acid or its substitute as a collector for rough selection. The mixture of acidic water glass is used as an inhibitor of calcium-containing minerals, the ratio of ** to acid water glass is 1:0.5 to 1:2, and the combined amount is 0.5 to 1.5 kg/t of raw ore. The fluorite decalcification and beneficiation process provided by the present invention has the advantages of high calcium removal efficiency, simple process, and low cost, and a high-grade fluorite concentrate with low calcium carbonate content can be selected from the high-calcium type fluorite ore.

2 Natural Fluorescent Fluorescent Coating A natural fluorite fluorescent coating processing technology, the process is beneficiation - comminution - preparation - mixing - sintering. The invention has the advantages of simple process and low cost and can meet the needs of arts and crafts paints and various articles with fluorescent effect requirements.

A method for preparing a fluorite flotation agent A preparation method for preparing a fluorite flotation collector, wherein an intermediate product of oleic acid is used as raw materials, crude fatty acids or mixed fatty acids, and the weight thereof is added to 3% of the weight of fatty acids. A 15% concentration was used to cause a catalyzed reaction, and a beneficiation frother formulation product was added to the reaction product in a weight of 0.4% to 3% by weight of fatty acid. The method provided by the invention has low production cost, and the produced fluorite float has the advantages of strong collection ability of collector, good water solubility and good dispersibility, and is suitable for flotation of fluorite at normal temperature and low temperature.

4 Fluorite Flotation Regulator Composition A flotation fluorite ore beneficiation process method is an improvement over the approved patent 87105202. In the prior art, flotation fluorite ore uses acid jacketing and synergist as an adjusting agent. In the present invention, a composition obtained by mixing water glass with acid and one or more soluble salts of the acid is used as an adjusting agent, and a composition series is formed, ie, **, **, **, oxalic acid, acetic acid can be used. For any of the acids and corresponding salts, the combination ratio is in the range of water glass, acid, salt = 1-2:1-5:0.5-1. The invention has strong adaptability, good stability, high quality of concentrate, high recovery rate and low cost.

5 Carbonate-fluorite ore flotation separation method The present invention provides a carbonate- fluorite ore cost-effective flotation separation method, particularly suitable for the flotation separation of fluorite ore with high carbonate content. . The key lies in choosing an effective carbonate mineral inhibitor—acidified water glass and dosing measures. In the conventional process conditions, the high-purity sorting of carbonate and fluorite can be achieved.

6 Method for Flotation of Fluorite The fluorite ore beneficiation apparatus The present invention relates to a method for flotation of fluorite ore with a conditioner. The invention adopts a mixture composed of an acid, a base and a synergist as an adjusting agent, adopts oleic acid or sodium lauryl oil as a collector, and the process flow is a composite circuit, and the fluorite ore is carried out under near-neutral and normal temperature conditions. The flotation, obtained fluorite concentrate high recovery, product quality, low impurity, low consumption of chemicals, low cost, suitable for all types of fluorite concentrator application.
