Embodiment 2

[0028] One-time grinding (64%-200 mesh), one-time classification, one-time roughing, six-time beneficiation, and two-time sweeping; After being dried by the tumble dryer, the finished product is packed into tons of bags; the flotation tailings enter the tailings pond, and the waste water is reused.

[0029] (1) Grind the fluorite ore first.

[0030] (2) Rough selection: use oleic acid as collector, sodium hydroxide and sodium carbonate as regulator, water glass, starch, sodium sulfate, hydrochloric acid, oxalic acid and sodium hexametaphosphate as quartz inhibitor, and carry out flotation rough selection Treatment, the flotation pH value control range was adjusted to 9.

[0031] (3) Selection: Sodium hydroxide and sodium carbonate are used as regulators, and water glass, starch, sodium sulfate, hydrochloric acid, oxalic acid, and sodium hexametaphosphate are used as quartz inhibitors to carry out flotation and selection treatment, and the pH value of flotation The control ra...

Abstract

The invention discloses a fluorite beneficiation and separation method, and relates to the technical field of beneficiation process. The fluorite beneficiation and separation method includes the stepsof primary grinding, primary grading, primary roughing, senary refining and secondary scavenging, and specifically includes feeding flotation concentrates into a concentration tank, dehydrating the concentrated concentrates by a filter, drying the filtered concentrates by a roller dryer, putting the dried concentrates into jumbo bags to obtain finished products, feeding flotation tailings into atailings pond, recycling wastewater, collecting fluorite by oleic acid, taking water glass as a quartz inhibitor, and adjusting the pH of ore pulp to 8-9 by calcium carbonate. The fluorite beneficiation and separation method has the advantages of high flotation efficiency, simple process and low cost.

Description

technical field [0001] The invention relates to the technical field of beneficiation technology, in particular to a method for beneficiation and separation of fluorite. Background technique [0002] The beneficiation method used for calcium removal of fluorite at home and abroad is mainly flotation method. By selecting appropriate flotation reagents, the difference in surface characteristics between fluorite and calcium-containing minerals can be enlarged, so as to achieve the purpose of separation. "Flotation Separation of Fluorite and Calcite" published in the 12th issue of "Metal Mine" in 1996 introduced the method of flotation separation of fluorite and calcium-containing minerals, and the flotation reagents include collectors and regulators. The commonly used collectors are mainly oleic acid and its substitutes; there are many kinds of regulators, such as soda, lime, phosphate, water glass, tannins and lignin sulfonate. According to the paper, according to the properti...
