the process of the extraction of metals

Extraction of Metals: Methods, Processes Involved ...

2021-5-7  Extraction of metals from their compounds is also a reduction process. Besides using carbon (coke) to reduce metal oxides to metals, sometimes displacement reactions can also be used. The highly reactive metals such as sodium, calcium, aluminum, etc. are used as reducing agents because they can displace metals of lower reactivity from their ...

Introduction. Rare metals have actively entered the scope of industrial applications: electronics, aviation, superconductors, mobile power sources, etc. (Frohlich et al., 2017).As a rule, they are not widespread in the earth's crust; therefore, the volume of production and use of rare metals is relatively small due to the high degree of dispersion and complexity of extraction methods.

Extraction of Metals from Ores – Different Processes Involved

The main aim of designing an extraction process is to minimize the cost and gather the purest form of the metal as much as possible. The conventional metal extraction processes will be discussed elaborately on this concept page. The simpler the process, the better and more cost-effective it is for the industries to extract metals from their ores.
