Summary
• Froth flotation is the separation utilising the different surface properties of the minerals. • Magnetic separation is the separation dependent on magnetic properties. • High-tension separation is the separation dependent on electrical conductivity proper-ties. Extractive metallurgy deals with extraction of metals from their ores.
