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.
Oct 09, 2020 The science of extracting metals from their ores and utilizing them for various useful purposes is called metallurgy. The nature and properties of metals make its extraction difficult by using single method. Thus, it is important to know that no single process can be used for extraction of

A process for extracting precious metal from volcanic ore includes the steps of crushing the ore, heating the ore in a hydrogen atmosphere to soften oxide mineral encapsulating the precious metal, cooling the ore, grinding the ore, and processing the ore to extract precious metal.
Metallurgy is the process of extracting metals economically from their ores and refining the extracted raw material into purer form. The naturally occurring compounds of metals that are found in earths crust along with some impurities are called minerals. An ore is the mineral from which the metal can be extracted profitably and conveniently.
The various processes involved in the extraction of a metal from its ores and its refining constitute metallurgy of that metal. The non-metallic impurities of earth and rocks associated with ores are called gangue or matrix. The major component of gangue is silica SiO2 present as quartz.
