Odisha is the largest bauxite-producing state in India, accounting for a significant portion of the country's total production. Bauxite is the primary ore of aluminum, and Odisha's rich bauxite deposits are primarily found in the districts of Kalahandi, Rayagada, Koraput, and Sundergarh. These resources are essential for the aluminum industry, contributing to India's position as a leading producer of aluminum globally. The mining of bauxite also plays a crucial role in the economy of Odisha, providing employment and economic growth, although it has also raised environmental concerns related to deforestation and tribal displacement.
