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…What are processes to extract rare earth metals of high,,For metals, they are produced in molten salts in small batches. For each of these, it is a question of economics of the process (which includes environmental issues) since small scale production often has high relative labour costs so high labour areas need to be clever in their processes.Metallurgic Processes | Boundless Chemistry,Metal ores are formed in the process of ore genesis, and they are extracted through mining.
