Froth Flotation Principle and Process

Metal ores are formed as a result of ore genesis and extracted through mining. Extractive metallurgy is the process of extracting important metals from an ore and refining the extracted raw metals into a purer form. Froth flotation is mainly employed for the extraction of sulphide ores. Froth Flotation Process Principle

Froth Flotation Process

The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is …
