1. Bauxite: Bauxite is a mineral used for the production of aluminum. It is found in abundance in Chhattisgarh. The state is known for its rich deposits of bauxite, with major reserves located in the Surguja, Kanker, and Bastar districts. Chhattisgarh contributes significantly to India`s bauxite production.
2. Dolomite: Dolomite is a carbonate mineral that is commonly used in the production of refractory materials, construction aggregates, and fertilizers. Chhattisgarh is also known for its dolomite reserves. The state has significant deposits of dolomite, particularly in the Durg, Raipur, Bilaspur, and Rajnandgaon districts.
3. Iron ore: Chhattisgarh is one of the major iron ore producing states in India. The state has extensive reserves of high-grade iron ore, which are mainly found in the Bastar, Dantewada, Kanker, and Rajnandgaon districts. Iron ore is a crucial raw material for the iron and steel industry and is widely used in the manufacturing of various products.
4. Tin: Tin is not a mineral that is naturally found in significant quantities in Chhattisgarh. While some traces of tin might be present in the state, it is not a major mineral of economic importance in the region. Therefore, Option 3: 2 and 4 only, is incorrect.
To summarize, Chhattisgarh is known for the natural occurrence of bauxite, dolomite, and iron ore. However, tin is not found in significant amounts in the state. Hence, the correct answer is Option 4: 1, 2, 3, and 4.
