Explanations:The question pertains to the raw materials supplied to Tata Steel by the regions of Jamshedpur in Jharkhand and Keonjhar in Odisha. Tata Steel is one of the largest steel producers in India and requires various raw materials for its operations. Among these raw materials, manganese is a critical component used in the production of steel alloys.
Manganese is a metallic element that is essential in steel production because it improves the strength and durability of steel. It is often added to steel to enhance its properties, such as resistance to wear and tear, and to improve its ability to be hardened. The presence of manganese in steel also helps to reduce the formation of slag, which is a byproduct of the steel-making process.
Jamshedpur, located in Jharkhand, and Keonjhar, located in Odisha, are known for their rich deposits of manganese. These regions have significant manganese ore reserves, which are mined and processed to supply Tata Steel with the necessary raw material. The proximity of these regions to Tata Steel's operations in Jamshedpur makes them ideal sources for manganese supply.
It is important to note that while coal, power, and water are also essential for the steel production process, they are not considered raw materials in the same way that manganese is. Coal is used as a fuel in the steel-making process, power is required to operate the machinery and equipment, and water is used in various processes such as cooling and cleaning. However, these are not directly supplied as raw materials for the production of steel alloys.
Therefore, the correct answer is that Jamshedpur in Jharkhand and Keonjhar in Odisha provide manganese as a raw material to Tata Steel. This understanding of the specific raw materials and their sources is crucial for comprehending the industrial processes and resource management in the steel industry.
