Extraction of Metals - Methods of Extraction of Metals from Ores

The extraction of metals from ores is what allows us to use the minerals in the ground! The ores are very different from the finished metals that we see in buildings and bridges. Ores consist of the desired metal compound and the impurities and earthly substances called Gangue. The extraction of metals and its isolation occurs over a few major ...

Mercury processing - Extraction and refining | Britannica

Extraction and refining Pyrometallurgy. The pyrometallurgical extraction of mercury from its ore is essentially a distillation process. When heat is applied to the sulfide ore in the presence of air, oxygen combines with the sulfur to form sulfur dioxide, and the metal is liberated at a temperature above its boiling point.

Bismuth: extraction-Metalpedia

The extraction from ores in which the bismuth is present in the metallic condition may be accomplished by a simple liquation, or melting, in which the temperature is just sufficient to melt the bismuth, or by a complete fusion of the ore. The first process never extracts all the bismuth, as much as one third being retained in the matte or speiss.

Types of Extraction | S-cool, the revision website

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 extract from its compound.
