Extraction of Metals: Ores and Minerals

Isolation of elements in Chemistry class 12 aims to teach the students about various processes of extraction of metals from or Very few metals such as the noble metals, ie, Gold, Silver, and Platinum etc are present in their original metallic forms in nature Metallurgy is the field of science which deals with the extraction of metals from ores which are naturally found in the environmentPhytomining is a method of extracting metals from low grade ore and spoil Metal tolerant plants are deliberately grown on mining waste then harvested and a new crop planted The harvested plants are treated and the metals extracted This has many benefits - it reduces the levels of toxic metals in the environment, increases the quantity of metal extracted from a mine and increases the profit.

Obtaining and using metals

Most metals are extracted from ores found in the Earth's crust It is more expensive and wasteful to extract a metal from a low-grade ore, but most high-grade ores have already been usedgenerally extracted by subjecting their ores to reduction by chemical methods or by electrolytic methods The process of extracting pure metal from its ore is known as metallurgy Since, the nature of the ore and also the properties of different metals are different, therefore, it is not possible to have the universal scheme which may be applicable to all the metals.
