Low-grade fluorite ore beneficiation process route assay method and process method

Abstract

The invention discloses a low-grade fluorite ore beneficiation process route assay method. The method is characterized by comprising the following steps: crushing raw ore to particles of 2 mm through a jaw crusher and twin rollers, uniformly mixing through a cone stacking method, and proportioning by using a square method as an ore sample for test; grinding four ore samples until the fineness of 60 percent, 70 percent, 80 percent and 90 percent of the ores is smaller than 200 meshes, then testing respectively under the conditions that the core grinding concentration is 50 percent, the using amounts of roughing agents are that the using amount of sodium carbonate is 500 g / t, the using amount of oxidized paraffin soap is 400 g / t, and the using amount of water glass is 500 g / t; the using amount of the scavenging agent is that the using amount of the oxidized paraffin soap is 100 g / t; determining percentage of the ore of which the process route rough grinding fineness is smaller than 200 meshes according to a quadruplet CaF2 cumulative recovery rate; determining using amounts of the roughing agents of the sodium carbonate, the water glass and the oxidized paraffin soap by using an L934 orthogonal method. The process route assay method has high practicability, obvious effect and obvious benefit.

Description

technical field [0001] The invention relates to a beneficiation process method of fluorite ore, in particular to a method for verifying the beneficiation process route of low-grade fluorite ore and a process method. Background technique [0002] my country's fluorite resource reserves rank first in the world, with huge production and export volumes. It is mainly used as raw material for the production of aluminum smelting flux cryolite in the metallurgical industry, hydrofluoric acid in the chemical industry, various fluorine salts and refrigerant Freon. It can also be used for In aerospace, aviation, electronics, electric power, building materials industry, light industry, optics, sculpture and many other fields, fluorite has become an indispensable and important mineral raw material in modern industry. With the development of science and technology and national economy With continuous development, its demand is also growing steadily. my country's fluorite resources are wide...

AI Technical Summary

Problems solved by technology

my country's fluorite resources are widely distributed, and there are many types of deposits. There are mainly four series of varieties, namely fluorite lump ore, fluorite concentrate, fluorite powder ore, optical and engraved fluorite. For silicic acid with less carbonate mineral content Salt fluorspar mines can be easily separated from gangue to obtain high-quality fluorspar concentrates with the existing technology, but it is difficult to meet the requirements of many low-grade fluorspar mines with existing fixed processes To produce products that meet the requirements, different low-grade fluorite mines need to use different beneficiation process routes that match their characteristics. If the process route is determined unscientifically, it will greatly affect the development of fluorite mines, resulting in low output standards. Many low-grade ores are not fully utilized, resulting in waste of resources, and there is no particularly good method for determining the existing process route, which still needs to be improved by process innovation
