Metals are usually extracted from ores using a combination of heating and reduction with carbon in the form of charcoal or coke. Not all metals can be extracted from their ores in this manner and may need to be extracted by a process called electrolysis. Metals with low chemical activity, such a gold and silver are normally found in their pure

16.2 GENERAL PRINCIPLES OF EXTRACTION OF METALS The process of extracting the metals from their ores and refining them is called metallurgy . The choice of the process depends upon the nature of the ore and the type of the metal. The metal content in the ore can vary depending upon the impurities present and chemical composition of the ore

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

On the other hand, carbonated metal ores are heated in a vacuum for easy extraction of metals. This is called calcination. This is how a concentrated ore is again refined to gather purer metals. This is a gist of how the extraction of metals ores and minerals is performed based on the physical and chemical properties of the impure ores

May 07, 2021 It is easier to do extraction of metals or obtain metal from its oxide, as compared to its sulfides and carbonates. Therefore, prior to reduction, the metal sulfides and carbonates must be converted into metal oxides. The sulfide ores are converted into oxides by heating strongly in the presence of excess air. This process is known as roasting
