SU1577846A1 - Method of supplying initial material to flotation machine - Google Patents

Abstract

This invention relates to mineral processing by flotation. The goal is to increase the performance of the flotation process by improving its hydrodynamic regime. Before feeding to the flotation machine (PM), the initial product is treated with reagents, then it is divided into two fractions through foaming: a frothy product and a burnt product. Foam product obtained from the source material, served on the surface of the foam layer in the chamber FM. The podopenny product, isolated from the source material, is directed inside the volume of aerated pulp to the zone of the FM aerator. At the same time, a product with a high content of a valuable component enters the foam layer, which speeds up the flotation process by eliminating the material of this fraction with the necessary stages of meeting particles with bubbles and fixing them on them. 1 il.

Description

The invention relates to the enrichment of minerals by flotation and can be used in the processing of ore and non-metallic raw materials.

The aim of the invention is to improve the performance of the flotation process by improving its hydrodynamic regime.

The drawing shows a device for implementing the method.

The method of supplying the original product to the flotation machine is carried out as follows.

The source material is treated with reagents, then, by foaming, it is divided into two fractions: a frothy product and a submerged product; inside the aerated volume of the flotation machine.

With this method of supplying the initial product, a product with a high content of a valuable component enters the foam layer, which makes it possible to speed up the flotation process by eliminating for the material of this fraction the necessary steps of meeting particles with bubbles and fixing them on them. At the same time, for hardly floated particles from the fraction of the bedding product sent to the flotation machine aerator area, the probability of meeting with air bubbles due to the exclusion of competition from the lightly floated grains increases, which contributes to an increased extraction of particles of the useful component.

The method of supplying the original product can be implemented using a device for preparing the initial product for the flotation process.

The device contains a chute 1 mounted above the camera of the photomachine. Above the vj

A separating plate 2 is installed on the forehead 1. On the sides of the chute 1 there is an unloading plate 3 and a pipeline 4. The starting product together with the reagents is fed into the chute 1 under the lower edge of the plate 2 in the form of jets that eject the air and disperse it. The foam product formed on the surface of the pulp is rolled over the left side of the chute 1 and through the plate 3 enters the foam layer in the flotation chamber. The podpyenny product, overflowing through the lower right side of the chute 1, is directed through pipeline 4 into the volume of aerated pulp in the area of the flotation machine aerator.
