Embodiment 1

[0018] Embodiment 1, with reference to figure 1 , a flotation enrichment process of siliceous-calcium fluorite ore, the siliceous-calcium fluorite ore is crushed and ground to dissociate the constituent mineral monomers, and water is added to adjust the slurry to a concentration of 20% ore, and then Flow into the stirring tank, and then add regulator sodium carbonate, water glass, S711 and collector sodium oleate to the slurry to adjust the slurry. The material after slurry adjustment enters the flotation system for rough separation, and the product in the tank is tailings X1 , discharged and piled up, the rough selection foam product is added to the water glass for slurry mixing, and the first selection is carried out after the first selection foam is added to the water glass slurry, and then the second selection is carried out. The product in the selection tank, that is, the secondary refined medium ore, is mixed and added with regulator sodium carbonate, water glass, S711 a...

Embodiment 2

[0019] Embodiment 2, with reference to figure 1 , a flotation enrichment process of siliceous-calcium fluorite ore, the siliceous-calcium fluorite ore is crushed and ground to dissociate the constituent mineral monomers, and water is added to adjust the slurry to a concentration of 50%, and then Flow into the stirring tank, and then add regulator sodium carbonate, water glass, S711 and collector sodium oleate to the slurry to adjust the slurry. The material after slurry adjustment enters the flotation system for rough separation, and the product in the tank is tailings X1 , discharged and piled up, the rough selection foam product is added to the water glass for slurry mixing, and the first selection is carried out after the first selection foam is added to the water glass slurry, and then the second selection is carried out. The product in the selection tank, that is, the secondary refined medium ore, is mixed and added with regulator sodium carbonate, water glass, S711 and c...

Abstract

The invention relates to a floatation and enrichment process for silicon-calcium mass type fluorite ores, which is characterized by comprising the following steps: dissociating the constituent mineral monomers of the silicon-calcium mass type fluorite ores by crushing and ore grinding, flowing into a stirring tank after adding water and regulating pulp, then adding a regulating agent of sodium carbonate, water glass, S711 and a collecting agent of sodium oleate into the ore pulp for regulating the pulp, roughing the material of which the pulp is regulated, selecting roughed foam for the firsttime, selecting the foam which is selected for the first time for the second time, combining a product in a primary selecting tank, i.e. middlings which are selected for the first time and a product in a secondary selecting tank, i.e. middlings which are selected for the second time, adding the regulating agent and the collecting agent of the sodium oleate, regulating the pulp, selecting the material of which the pulp is regulated again, returning the foam which is selected again for the roughing operation, selecting the foam which is selected for the second time for the third time until selecting for the fifth time, returning the middlings which are selected for the third time, the fourth time and the fifth time by adopting the separating operation, grading the foam which is selected forthe fifth time by a cyclone, overflowing the cyclone, concentrating and filtering to obtain a fluorite concentrate product. The process disclosed by the invention has the advantages of high separation efficiency, excellent process index, high quality of obtained fluorite concentrates and the like.

Description

technical field [0001] The invention belongs to the technical field of fluorite ore flotation, in particular to a flotation enrichment process suitable for quartz-carbonate-fluorite ore (silicon-calcium type fluorite ore). Background technique [0002] Fluorspar, also known as fluorspar, is an important non-metallic mineral raw material, widely used in metallurgy, aluminum smelting, glass, ceramics, cement, chemical industry and other fields. With the advancement of science and technology and the development of social economy, fluorite is becoming more and more important as a basic industrial raw material and has become a strategic material. The total reserves of fluorite in my country account for more than 2 / 3 of the world's reserves, ranking first in the world. Fluorite ore is divided into quartz-fluorite ore, carbonate-fluorite ore and polymetallic-fluorite ore according to its output characteristics. The characteristics of fluorite resources in my country are that ther...
