Types of Extraction | Scool, the revision website

Types of Extraction | Scool, the revision websiteMethods 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.

Metals | chemistrynotes

Metals | chemistrynotesGold is an element our ancestors used most. Gold is also a native mineral and so is not found mixed with other minerals because it is a nonreactive metal. And because at that time uor ancestors did not know how to separate the different elements due to their lack of chemical knowledge they felt it most suitable to use the element of gold metal.

How to extract metals from ores Quora

How to extract metals from ores QuoraSteel and iron are extracted by taking iron ore and placing them in a crucible with a different material on top to attract the oxygen in the ore, known as flux. They heat the crucible and the flux grabs the oxygen that becomes available, leaving only pure iron that can then either be added to for alloys and to make steel or simply poured raw.
