Sulphide ores can be easily wetted by the oils, which will float on water. These minerals are first converted into a fine powder and then mixed with water. After that, pine oil is poured into this slurry. Then air bubbles are created by injecting high-pressure air. Thus, the sulphide ore comes on top of the froth and oil.
Igneous rocks are commonly more magnetic than sedimentary rocks. There is also a subdivision of magnetic properties inside igneous rock groups based on composition. Mafic igneous rocks (gabbro or peridotite) have more magnetic minerals than felsic. Igneous rocks are not so magnetic to be attracted by magnets.

This method concentrates the ore by passing it through an upward stream of water whereby all the lighter particles of gangue are separated from the heavier metal ore. This is a type of gravity separation. Magnetic Separation: This involves the use of magnetic properties of either the ore or the gangue to separate them.
