What are the raw materials they use?
Different industries use different raw materials based on their manufacturing requirements. Iron and Steel Industry uses iron-ore, coking coal, and limestone as its chief raw materials. These are heavy raw materials that determine the location of steel plants.
The Aluminium Industry uses bauxite as its primary raw material. The bauxite is first crushed to extract alumina, which is then processed in smelters. The Sugar Industry uses sugarcane as its basic raw material.
Agro-based industries like cotton, jute, silk, woollen textiles, sugar and edible oil industries derive their raw materials from agriculture. These include crops like cotton, jute (known as the 'Golden Fibre'), and sugarcane.
Explanation
The question asks about raw materials used by industries. From the context, we can identify raw materials for several key industries: Iron and Steel (iron-ore, coking coal, limestone), Aluminium (bauxite), Sugar (sugarcane), and Agro-based industries (agricultural products like cotton, jute). The puzzle activity confirms sugarcane as the basic raw material for sugar industry and mentions jute as the 'Golden Fibre'. The aluminium manufacturing process diagram clearly shows bauxite as the raw material.
Solution Steps
Step 1: Identify the industries mentioned in the context - Iron and Steel, Aluminium, Sugar, and Agro-based industries.
Step 2: Extract raw materials for each industry from the given information.
Step 3: Present the answer categorizing industries and their respective raw materials.
