Abstract

The invention discloses a method for producing a fertilizer by using fluorite tailings. The method comprises the following steps: removing magnetic substances from slurry containing fluorite tailingsand a separating agent by using a magnetic separator, obtaining substances with small specific gravity by using a spiral chute, and adding sulfuric acid and liquid ammonia for a reaction to obtain a compound fertilizer. According to the application, elements such as phosphorus, potassium, calcium, silicon, magnesium and sulfur in the fluorite tailings can be utilized, so that resource waste and environment pollution caused by directly discarding the fluorite tailings are avoided, meanwhile, the production cost is reduced, and the enterprise benefit is increased.

Description

technical field [0001] The invention relates to the field of non-metallic ore dressing, in particular to a method for producing fertilizer by using fluorite tailings. Background technique [0002] In the prior art, when using fluorite ore for mineral processing, only calcium fluoride is selected, and about 1 ton of calcium fluoride is selected from 3 tons of fluorite ore, and the other two tons are used as tailings. Fluorite tailings contain a large number of elements suitable for fertilizers, such as phosphorus, potassium, calcium, silicon, magnesium, sulfur and other elements. Recycling these components to make fertilizers can greatly reduce the waste of resources and increase the benefits of enterprises. Contents of the invention [0003] The purpose of the present invention is to provide a method of using fluorite tailings to produce fertilizers to solve the problem of directly discarding elements such as phosphorus, potassium, calcium, silicon, magnesium and sulfur in...
