Froth Flotation Principle and Process
Metallurgy is the process of extracting a metal in its pure state from its ore on a large scale using any physical or chemical means. 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.
