    Introduction to Mineral Processing - cpchem

    Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.

    In fact, reverse flotation of coal enables to remove these undesired mineral content from coal structure not only in macro size but also in micro size. On the other hand, like undesired minerals, valuable ones like vanadium, germanium, etc. are also taken from coal particles by using the same procedure.

    Froth Flotation of Iron Ores - sapub

    Reverse cationic flotation removes quartz using ether amine as a collector, while depressing iron oxide with the use of corn starch in alkaline pulp adjusted by NaOH. In most cases, the pH ranges from 10 to 10.5. In early years, primary fatty amines such as dodecylamine were used in reverse cationic flotation.
