Overview of Mining Activity in Salem District Salem is a part of Western Tamil Nadu and is located at the base of the popular tourist destination of the Yercaud hills. Salem boasts large Textile, Steel, Automotive, poultry and sago industries. Salem also has one of the largest Magnesite deposits in India. As per the Department of Geology and Mining, a major part of the mineral wealth of Tamil Nadu is confined to Salem District, where a variety of important minerals like Magnesite, Dunite, Bauxite, Limestone, Iron ore, Quartz, Feldspar and Soapstone, Granites etc, are found.

BAUXITE: Bauxite, ore of Aluminium, occur in the form of cappings in the Shevaroy hills of Yercaud Taluk. The shevaroy hills are chiefly made up of the Charnockite group of rocks interBanded with metasedimentary units and cut across by dykes of dolerite. Only low grade bauxite available at the depth of maximum 2m in all the hills followed by ferruginous clay. 2. IRON ORE: A) KANJAMALAI The Iron ore deposits of Kanjamalai hill is of Banded Magnetite Quartzite. Kanjamalai is situated about 8 Km West of Salem Town. It is about seven kilometres long and four kilometres wide and rises to a maximum height of 986 metres above Mean sea level. The Iron ore outcrops of scattered, generally the Magnetite Quartzites occur at three distinct levels. The first or lowermost band occurs near to the base of the Kanjamalai. It can be traced over a length of some 13 Kilometres. The width is very variable (probably depending to some extent on the degree of tight folding) but the average width is about 25 metres. The second or middle band occurs some 300 metres about the plain. In outcrop it is discontinuous over its strike length of about 6 kilometres. The third and uppermost and occurs some 60 metres higher than the second band at a height of some 350 to 370 metres above ground level. The band is about 10 kilometres long (around the complete elliptical outcrop) and about 10 metres wide. The ore in the first and second bands appears similar with an iron content of 33 to 39% Fe. In the band cropping out at the highest level the rock is much more siliceous with a much lower iron content and there is more hematite present. This rock is best described as a ferruginous Quartzite and is of less economic potential than the lower bands. The Iron ore reserves in the first band (lower band) of Kanjamalai 99.3 Million Tonnes and second band reserves (middle band) is about 50 to 60 million tonnes.
