Detailed Solution

Minerals like copper, common salt, gold, bauxite, and coal, which are the minerals we use daily in our houses are being extracted from different natural sources. Igneous and metamorphic rocks are the source of copper, tin, lead, and zinc. It is from the sedimentary rocks, we can extract coal as beds and layers. It is on the surface of decomposed rocks that the formation of bauxite happens. From alluvial soil, which is also available on our river banks, we get minerals such as gold, silver, platinum, and tin. Minerals found in alluvial soil are not corroded by water. Common salt, which is our other daily use, can be extracted in large quantities from oceanic water along with magnesium and bromine.
