This document discusses methods for mining and separating minerals from waste materials, including magnetic separation using electromagnets to separate magnetic minerals like iron ore, and flotation which uses chemicals to form bubbles that attach to minerals and carry them to the surface of a slurry mixture for collection. Key minerals mentioned are copper, zinc, gold and silver.

PLANET EARTH AND BEYOND MINING OF MINERAL RESOURCES (SEPARATING MINERALS FROM WASTE)
MINERALS EXAMPLES Copper Zinc Gold Silver
SEPARATION METHODS MAGNETIC SEPARATION. FLOTATION.
MAGNETIC SEPARATION Magnetic minerals such as iron ore can be separated from non-magnetic wastes with the use of strong magnets (electromagnets) in the mining industry. In the picture is the mixture of non-magnetic sulfur and magnetic iron filings.
FLOTATION Flotation is the method that makes use of density separation. This happen with the mixture of water and minerals, with an addition of chemicals to form bubbles (in the slurry-the muddy-like mixture). These bubbles pop up through the slurry with minerals attached to them. Thus the minerals are easily collected. In the picture is the slurry , separating minerals by floating
