Types of Extraction | S-cool, the revision website

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, the more difficult it is to ...

IGCSE Extraction of Metals From Ores Notes - IGCSE And IAL ...

Extraction of Metals. Industries extract metals from their ores. What are ores? Let me explain in a simple way. Usually, less reactive metals such as gold and silver are found in their pure form in the soil. But this is not the case with more reactive iron or aluminum. Usually iron and aluminum exist as compounds, with oxygen, also known as oxides.

GCSE CHEMISTRY - Extraction of Metals - What is a Metal ...

Extraction of Metals. What is a Metal Ore?. A solid element or compound which occurs naturally in the Earth's crust is called a mineral.A mineral which contains a high enough percentage of a metal for economic extraction is called a metal ore. Economic extraction means that the cost of getting the metal out of the ore is sufficiently less than the amount of money made by selling the metal.

TOPIC EIGHT | EXTRACTION OF METALS | CHEMISTRY FORM …

The more reactive the metal is the more stable its compounds are, and the more energy is needed to break down the bond between the metal and oxygen. Therefore, the extraction of these metals requires a strong method of reduction: electrolysis (or electrolytic reduction).
