Mineral Processing Technology of Fluorite

(1) Natural fluorite, fluorescent paint
a natural fluorite optical coating process, the process is beneficiation - crushed - preparation - mixing - sintering. The present invention has the simple process, low cost to meet the arts and crafts with paint and a variety of fluorescence effect requires the needs of the articles.
(2) The composition of fluorite flotation modifier
A flotation of fluorite ore process, it is the improvement of 87,105,202 number of granted patents. Acid the jacketed plus synergist for adjusting agent in the flotation of fluorite ore using existing technology. The present invention, water glass and acid with the acid composition of one or a variety of soluble salt mixture composition adjusting agent, and the formation of the composition series, you can use sulfuric acid, hydrochloric acid, nitric acid, oxalic acid, acetic acid acid and the corresponding range of salt, combined ratio for the water glass • acid • salt = a ~ 2:1 ~ 5:0.5 ~ 1. The present invention is adaptable, good stability, high-quality concentrate, high recoveries and low cost.
(3) Flotation of fluorite
the present invention relates to the flotation of fluorite ore adjusting agent. The present invention uses a mixture of acids, alkalis, and synergist as adjusting agent, acid or rubber sodium oleate as a flotation process for the composite circuit fluorite mine in the near-neutral and room temperature conditions the flotation of fluorite concentrate, the high recovery rate, product quality, low impurity, pharmaceutical consumption, low cost, suitable for all kinds of fluorspar concentrator applications.
(4) fluorite in addition to calcium beneficiation process
A fluorite in addition to calcium mineral processing technology, it is a rough selection, multiple selection operations composed of oleic acid or its substitutes, as the collecting agent for roughing, a mixture of sulfuric acid and acidic sodium silicate as a calcium mineral inhibitor of sulfuric acid and acidic sodium silicate ratio of 1:0.5 to 1:2, the joint amount of 0.5 ~ 1.5kg / t ore. The present invention provides a fluorite addition to calcium beneficiation process In addition to the high calcium efficiency, simple process, low-cost advantages can be elected from the high calcium fluorite ore, calcium carbonate content is very low grade fluorite concentrate.
(5) Preparation of fluorite flotation agents
Preparation of fluorite flotation collectors on preparation method, the crude fatty acid or mixed fatty acids of oleic acid production of intermediate goods as raw material to him to join weight fatty acids 3% to 15% by weight of concentrated sulfuric acid, so that the occurrence of sulfated reaction, further reaction products by adding weight in weight of 0.4% to 3% of the dressing foaming agent Serve products of fatty acids. The present invention provides a method of producing low-cost production of fluorite floating choose collector capacity, water solubility, good dispersion, suitable for room temperature and low temperature flotation fluorite.

With its high quality products such as Raymond mill, Rock cone crusher, Magnetic separator, Ore beneficiation, Dryer machine, Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
