How metals are extracted

WebThe primary methods used to extract minerals from the ground are: Underground mining. Surface (open pit) mining. Placer mining. The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use. WebMore than seventy different metals are extracted and used in the manufacturing industries today. Some, like copper and lead for example, can be used in their pure state, to take advantage of their natural properties. But often, we combine different metals, or metal with other materials to form alloys.
