The natural substances in which the metals or their compounds occur in the earth metals can be conveniently and economically extracted are known as ores.
and machines for extracting metal from the ore focused on “eliquation” of metals. requires significant investments with regard to their treatment, although they
In view of this, the study of recovery of metals from their ores is very important. In this lesson, you shall learn about some of the processes of extraction of metals
Jan 9, 2018 The process of separating a metal from its ore is known as smelting. or clay is used to dip into the smelter to extract molten metal and ore.
Ores: The minerals from which a metal can be profitably extracted are called ores. Metals can be categorized into three parts on the basis of their reactivity:
The most common metal ores are oxides and sulfides. Sulfides are the oldest ores, formed in the Earths history when there was a lot of sulfur from volcanic
Smelting is a process of applying heat to ore in order to extract out a base metal. It is a form of extractive metallurgy. It is used to extract many metals from their
