Test: Manufacturing Industries in India-Mineral Based - Class 10 MCQ

The iron and steel industry primarily relies on iron ore, which serves as the main source of iron for steel production. Iron ore is extracted from mines and undergoes several processes to remove impurities before being converted into steel. Interestingly, India is now the fifth-largest producer of crude steel globally, showcasing the industry's significance in the country's economy.

The Tata Iron and Steel Company, established in 1907 in Jamshedpur, is recognized as the pioneer of the iron and steel industry in India. This company played a crucial role in industrializing India and set a benchmark for future steel production ventures in the country.

The automobile industry in India is characterized by being the sixth-largest producer of passenger cars and commercial vehicles in the world. This industry has seen significant growth and diversification, contributing to the country's economy.

The Shipbuilding Industry requires access to deep waters for the construction and launching of ships. This is essential for navigation and ensures that large vessels can be built and serviced efficiently near the water.

One major advantage of mini steel plants is their ability to meet local market demands. By producing steel locally, these plants help reduce transportation costs and alleviate pressure on larger steel production facilities, making them more sustainable.

Hindustan Aeronautics Limited (HAL) is headquartered in Bengaluru. Established in 1964, HAL is significant for its role in designing and manufacturing aircraft and related components, contributing to India's defense and aviation sectors.

Ore reduction is the process used to convert iron ore into pig iron. This process occurs in a blast furnace where impurities are removed by adding coke, limestone, and dolomite, allowing the molten iron to be collected at the base of the furnace. The resulting pig iron can be further processed into various forms of steel.

The Heavy Engineering Industry is primarily focused on manufacturing machinery and equipment for various sectors such as agriculture, transport, mining, and construction. This industry requires substantial capital and advanced technology, playing a crucial role in the infrastructure development of the economy.

The Indian Space Research Organisation (ISRO) is significant for conducting space research and launching satellites. It has played a pivotal role in advancing India's capabilities in space exploration and satellite technology, contributing to various sectors including communications and earth observation.

The Diesel Locomotive Works (DLW) primarily focuses on producing broad gauge and meter gauge diesel engines. This facility plays a vital role in supporting India's railway network by providing reliable locomotives for transportation.

Mini steel plants are known for utilizing ferrous scrap, pig iron, or sponge iron as their primary raw materials. They are often more cost-effective and environmentally friendly compared to larger steel plants, leading to their promotion by the government.

Coking coal is supplied from several coalfields including Jharia, Bokaro, Raniganj, Giridih, and Korba. These coalfields are vital for the steel-making process, as coking coal is essential for producing coke, which is used in the blast furnace for iron production.

The petrochemical industry predominantly produces synthetic fibers, plastics, dyestuffs, and various chemicals. These products have replaced many traditional materials due to their cost-effectiveness and versatility in applications across different sectors.

The Heavy Electrical Industry primarily focuses on manufacturing equipment used for power generation, transmission, distribution, and utilization. This includes generators, turbines, and other critical components necessary for energy infrastructure.

The shipbuilding industry primarily uses bulky raw materials, such as steel and aluminum, which are essential for constructing large vessels. The industry's proximity to these materials is crucial for efficient production and assembly processes.

Manganese is primarily used to harden steel and remove impurities during the steel-making process. It plays a vital role in enhancing the strength and durability of steel, making it a crucial element in alloying.

Low investment is NOT a requirement for heavy engineering industries. In fact, these industries typically require substantial capital investment to acquire advanced technology and machinery, as well as to maintain a large workforce for operations.

Limestone serves as a flux in the steel-making process. It helps to remove impurities from the iron ore by combining with them to form slag, which can be easily separated from the molten iron.

The Tata Iron and Steel Company is located in Jamshedpur, which is in the state of Jharkhand. This region was specifically chosen for its proximity to essential raw materials and transportation facilities.

The Tata Iron and Steel Plant sources its water supply from the Kharkai River. Water is a critical resource in the steel manufacturing process, used for cooling, processing, and other operational needs.
