Oct 6, 2014 Once the ore is mined, the metals must be extracted, usually by chemical or electrolytic reduction. The methods used depend on the metal and
Jan 9, 2018 The process of separating a metal from its ore is known as smelting. as the Inca and the Greeks, used primitive techniques to separate ore and metal. or clay is used to dip into the smelter to extract molten metal and ore.
The method used to extract a metal depends on where the metal is in the reactivity series.
Smelting is a process of applying heat to ore in order to extract out a base metal. It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, .

Very few metal ores occur in a pure enough form to be used directly in the of metal. Metals that are extracted by reductive processes usually need to be further
Metallurgy-the art and science of economically concentrating, extracting, that can occur as metals in their natural state-were used as long as 10 000 years ago. Whether or not a metal-bearing deposit is classified as an ore, a reserve, or a Many processes proposed for extraction of lunar materials are energy-intensive.
Aluminium is the most widely used metal after iron. Aluminium and its alloys are extensively used in transport applications trains, aeroplanes, ships and cars Primary manufacture involves four processes: a extraction of the ore, bauxite
This makes aluminum the most abundant metal and the third most abundant element in After the ore is discovered, open-pit mines typically provide the bauxite that will This is accomplished using a technique developed by Karl Joseph Bayer, But its primary use is to act as a starting point to extract pure aluminum.
