Equipment used for crushing fluorite tailings, crushing method and fluorite flotation method

Abstract

The invention provides equipment used for crushing fluorite tailings and a crushing method. The equipment comprises a tailing receiver and a first stirrer, wherein a first vibrating screen is connected above the first stirrer, a fist collector is arranged below the first vibrating screen, the first vibrating screen is connected with a second stirrer which is connected with a second vibrating screen, a second collector is arranged below the second vibrating screen, the second vibrating screen is connected with a third stirrer which is connected with a third vibrating screen, and a third collector is arranged below the third vibrating screen; the third vibrating screen is also connected with a material collector; the first collector, the second collector and the third collector are all connected with a fourth collector. The invention also provides the method for using the equipment and a fluorite flotation method. The invention has the beneficial effects that the fluorite concentrate obtained by flotation has good quality, is high in recovery and low in cost, and is suitable for being applied in various fluorite flotation factories.

Description

technical field [0001] The invention relates to a method of extracting remaining CaF in fluorite flotation tailings by using a stirring mill as a grinding device 2 The method, in particular relates to a device and method for grinding fluorite tailings with simple process and strong operability. Background technique [0002] The first equipment used for mine crushing was the jaw crusher, which was first widely used in road construction and later in mines. It has the characteristics of large crushing ratio, simple structure, reliable operation, easy maintenance and low operating cost. Jaw crushers are widely used in mines, smelting, building materials, highways, railways, water conservancy and chemical industries, etc., but their disadvantages are: (1) bulky and heavy; (2) strong vibration and noise during operation, requiring It has a solid foundation; (3) consumes a lot of energy; (4) the friction loss between the ore and the machine body is very large; (5) the particle si...

Problems solved by technology

Jaw crushers are widely used in mines, smelting, building materials, highways, railways, water conservancy and chemical industries, etc., but their disadvantages are: (1) bulky and heavy; (2) strong vibration and noise during operation, requiring It has a solid foundation; (3) consumes a lot of energy; (4) the friction loss between the ore and the machine body is very large; (5) the particle size of the product is very uneven

Generally speaking, for low-grade fluorite ore or refractory fluorite ore, the crushing degree is closely related to the flotation recovery rate and product quality of fluorite. Abandoned fluorite tailings contain 6-10% calcium fluoride. The remaining calcium fluoride in this type of tailings is mainly in two states. One is that the fluorite and quartz joints have not been fully dissociated. It is due to the uneven embedded particle size of fluorite ore, so that in the ball mill grinding body, the fluorite with fine embedded particle size cannot be fully dissociated

In the flotation operation of these two cases, the probability of being flotation is very low
