Abstract

Abstract

Coarse particle flotation technology increases the upper limit of the floatable particle size of mineral particles, and can reduce energy consumption, which is of great significance for pre-separation tailings, coarse tailings re-separation, especially for the flotation of minerals that are easy to be crushed. In recent years, many coarse-grained flotation technologies have appeared, and most of them are used in the separation of minerals such as coal and phosphate minerals. Based on the analysis of the properties of coarse-grained minerals and their difficulties in flotation, this paper proposes to improve coarse-grained flotation. This paper summarizes the relevant flotation methods such as froth flotation method, flash flotation method, fluidized bed flotation method and related equipment, and introduces the advantages and disadvantages of different methods in practical production.
