How do you extract metals from their ores

How do you extract metals from their ores

Feb 08, 2021· There are 3 main methods of extracting metals from their ore. They are reduction of the ore with carbon, reduction of the molten ore by electrolysis, and reduction of the ore with a more reactive metal. How is carbon and hydrogen used to purify metals? Carbon reacts with oxygen to form carbon dioxide, and hydrogen reacts to form water. These methods are preferred when purifying metals from their ores.

25.2 Extracting ores Mining of mineral resources Siyavula

Ore is removed from the crust by mining, either on the surface (open pit mining) or underground (shaft mining or room and pillar mining). Some minerals can be used in their natural form, for example sand in the building industry, phosphate rock for fertilisers and diamonds in jewellery.

The process used to treat sulfide copper ores begins at the mine site, where the copperbearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.
