Extracting Metals by Reduction - todhigh

2018-3-2  Metals less reactive than carbon can be extracted from their ores by reduction. Copper, silver, gold and platinum can occur as native metalsand do not need to be extracted. Sometimes copper needs to be extracted from an ore. ty potassium sodium calcium magnesium aluminium zinc iron copper gold lead silver (carbon) (hydrogen) platinum

Extraction of Metals Good Science

Metals with an intermediate reactivity, such as iron and zinc, are chemically extracted from minerals by a process known as carbon reduction. Carbon reduction is a type of redox reaction, where carbon is used to displace a metal from a compound.

Extraction of metals and the reactivity series. The most reactive metals are at the top of the series; The tendency to become oxidised is thus linked to how reactive a metal is and therefore its position on the reactivity series; Metals higher up are therefore less resistant to oxidation than the metals placed lower down which are more resistant to oxidation

The extraction of metals CPD RSC Education

2019-12-11  • An ore is a mineral that contains enough metal to make it worth extracting the metal. Carbon can be used to extract metals from some metal oxides. • A metal can either be reduced or oxidised in a reaction. • Reduction occurs when a metal in a compound loses oxygen, to form the elemental metal.

Types of Extraction S-cool, the revision website

2 天前  Methods of extraction Many metals are found in the Earth's crust as ores. An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is. The more reactive the metal
