1 fluorite removal calcium dressing process
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.
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
A preparation method for preparing a fluorite flotation collector, wherein a crude fatty acid or a mixed fatty acid produced by oleic acid is used as a raw material, and concentrated sulfuric acid having a weight of 3% to 15% by weight of a fatty acid is added thereto 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 the advantages of strong collecting ability of the collector, good water solubility and dispersibility, and is suitable for flotation of fluorite at normal temperature and low temperature.
4 fluorite flotation regulator composition
A process for flotation of fluorite ore, which is an improvement of the patent granted to 87105202. In the prior art, the flotation fluorite ore is acid-added with 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 the ratio of water hyaluronate = 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 present invention provides a cost-effective flotation separation method for carbonate-fluorite ore, which is particularly suitable for flotation separation of fluorite ore having a 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
The present 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.
Braille labels are made by embossing or printing Braille characters onto adhesive or non-adhesive materials.The labels may include both the Braille characters and corresponding print or visual information, allowing both blind and sighted individuals to easily identify the labeled item.These labels play a crucial role in promoting independence and accessibility for individuals with visual impairments.By providing information in Braille, individuals who are blind can independently navigate their environment, locate items, and access important information without relying on sighted assistance.Braille labels are commonly used in various settings, including homes, schools, workplaces, and public facilities, to ensure that individuals with visual impairments have equal access to information and resources.
