Basic Principles Variables Affecting Froth Flotation

2016-03-12  The purpose of the oil in froth-flotation is (1) to form, together with the water and solid of the pulp and the gas introduced into the pulp, a froth; and (2), to aid in the selection of the particles of mineral of metallic, resinous or adamantine luster in the pulp from the gangue minerals. Not all oils will perform both of these functions with all ores in all processes. Newly refined ...

Recovery rates on a flotation plant can be around 90% and often lower, making flotation one of the least efficient processes in the concentration path. Hence, over the last few decades much research and development has gone into the stabilization and optimization of flotation circuits. Flotation is a process with many ...
