1 fluorite removal calcium dressing process CN99114389 The invention discloses a fluorite calcium removal beneficiation process, which is composed of one rough selection and multiple selection operations, and is roughly selected by using oleic acid or its substitute as a collector , and a mixture of sulfuric acid and acidic water glass. As an inhibitor of calcium-containing minerals, the ratio of sulfuric acid to acidic water glass is 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. 2 natural fluorite fluorescent coating 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. 3 Method for preparing fluorite flotation agent The invention discloses a preparation method for preparing a fluorite flotation collector, which uses a crude fatty acid or a mixed fatty acid produced by oleic acid as a raw material, and adds concentrated sulfuric acid having a weight of 3% to 15% by weight of a fatty acid. The sulfation reaction occurs, and 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. 4 fluorite flotation regulator composition The present invention is a process for flotation of fluorite ore, which is an improvement of the approved patent of No. 87105202. 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 to 2:1 to 5:0.5 to 1. The invention has strong adaptability, good stability, high quality concentrate, high recovery rate and low cost. 5 carbonate-fluorite ore flotation separation method The invention provides a cost-effective flotation separation method for carbonate-fluorite ore, and 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. 6 Method of flotation fluorite This invention relates to a method of flotation of fluorite ore with a conditioning agent. The invention adopts a mixture composed of an acid, a base and a synergist as a adjusting agent, and uses oleic acid or sodium oleate as a collecting agent, and the process flow is a composite circuit, and the fluorite ore is carried out under near neutral and normal temperature conditions. The flotation has high recovery rate of fluorite concentrate, good product quality, low impurity content, low chemical consumption and low cost, and is suitable for various fluorite ore dressing plants.
