Mineral processing A fluorite decalcification beneficiation process consisting of a rough selection and multiple selection operations, using oleic acid or its substitute as a collector for rough selection, and a mixture of sulfuric acid and acidic water glass as a calcium-containing mineral The inhibitor has a ratio of sulfuric acid to acidic water glass of 1:0.5 to 1:2, and the combined amount is 0.5 to 1.5 kg/t of ore. The fluorite decalcifying ore dressing process provided by the invention has the advantages of high calcium removal efficiency, simple process and low cost, and a special grade fluorite concentrate with low calcium carbonate content can be selected from the high calcium type fluorite ore. Coating process A natural fluorite light coating processing process, the process of which is beneficiation-crushing-preparation-mixing-sintering. The invention has the advantages of simple process and low cost, and can meet the requirements of paints for arts and crafts and various articles with fluorescent effects. Preparation of the preparation. A preparation method for preparing a fluorite flotation collector, which comprises using a crude fatty acid or a mixed fatty acid produced by oleic acid as a raw material, and adding concentrated sulfuric acid having a weight of 3% to 15% by weight of a fatty acid to cause sulfation. In the reaction, a beneficiation foaming agent having a weight of 0.4% to 3% by weight of the fatty acid is added to the reaction product. The method provided by the invention has low production cost, and the fluorite float produced has strong collector ability, good water solubility and good dispersibility, and is suitable for flotation of fluorite at normal temperature and low temperature. Fluorite mine Conditioner composition A process for flotation of fluorite ore, which is an improvement of the approved patent of 97105202. In the prior art, the flotation fluorite ore is an acid addition sleeve and a synergist as a regulator. In the present invention, a composition obtained by mixing an acid with water and one or more soluble salts composed of the acid as a regulator, and forming a series of compositions, that is, any one of sulfuric acid, hydrochloric acid, nitric acid, oxalic acid and acetic acid can be used. The acid and the corresponding salt are in the range of water glass, acid and salt = 1~2:1~5:0.5~1. The invention has strong adaptability, good stability, high quality concentrate, high recovery rate and low cost. Flotation separation method A carbonate-fluorite ore is provided for cost-effective flotation separation, which is particularly suitable for flotation separation of fluorite ore with high carbonate content. The key is to select an effective carbonate mineral inhibitor - acidified water glass and dosing measures to achieve high purity separation of carbonate and fluorite under normal process conditions.
