(2) Due to the large specific surface of sludge, they will absorb a large amount of flotation reagents in the pulp, which reduces the reagent concentration in the pulp, destroys the normal flotation process, and reduces the flotation index. (3) Because the slime is very fine and has a large surface area, the surface activity is increased.
The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore (usually the valuable ones) are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp. In …

A new flotation process to recover alunite from low-grade alunite ores is described. The process begins with run-of-mine ore, reduced to less than 5 mm (0.2 in.), being preconditioned with the reagents before grinding and alunite flotation. From the preconditioning step, ore particles, impregnated with reagents, form pellets that …
