Keywords: flotation, process optimization, Taguchi orthogonal array, ANOVA. 1. Introduction Froth flotation is widely used for separating base metal sulphide minerals in complex ores. One of the major challenges faced by the flotation of these ores is the ever
The flotation process is characterized by the following: Involves the injection of fine gas bubbles into the water phase Gas bubbles in the water adhere to the oil droplets Buoyant force on the oil droplet is greatly increased by the presence of the gas bubble
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
Flotation is the primary concentration process based upon the interfacial chemistry of mineral particles in solution, other processes based on surface properties include:
fi ion process to be automated, with a very rapid separation of the solid and liquid phases. The principle of flotation Flotation is a dynamic clarifi ion system, where the relatively simple principle is fairly similar to an inverted static clarifi ion. deposits from ...

Flotation process refers to the general term that the slurry flows through the various operations during ore flotation. In flotation operations, different flotation processes should be adopted for different types of ore. Therefore, the flotation process can reflect the technological characteristics of the ore. ...
