(c) The decline in international demand for Indian iron ( ore from the Western coastal region.
(d) Adoption of sponge from technology.

Correct Answer: (b) The occurrence of high-grade iron ore deposits in Goa and parts of Madhya Pradesh and the comparative ease of exporting steel from here.

Solution:Some iron and steel plants have been planned along the western coast of India. The major reasons for the locational shift of this industry are occurrence of high-grade iron ore deposits in Goa & parts of Madhya Pradesh as well as sea- ports for comparative case of exporting steel and consumption of iron ore in the concerned field for manufacturing.

(a) Saltpetre
(b) Rock phosphate
(c) Coking coal
(d) All of the above

Correct Answer: (c) Coking coal

Solution:Iron and Steel industry is one of the important industries of India. It requires minerals like Iron ore, Coking coal, manganese, dolomite, rock phosphate, chromium, etc. In India, coking coal is mainly imported from Australia. Coke is produced by heating coking coal. Coking coal is also known as Metallurgical coal.

15. The local supply of coal is not available to: [I.A.S. (Pre) 1996]

(a) TISCO, Jamshedpur
(b) VSL, Bhadravati
(c) HSL, Durgapur
(d) HSL, Bhilai

Correct Answer: (b) VSL, Bhadravati

Solution:VSL, Bhadravati is the only Iron and steel plant situated outside the coal producing area. The absence of coal was met by the use of charcoal derived from firewood obtained from state forest. The plant switched over to electric furnaces after the completion of Mahatma Gandhi Hydel Power Stations.

16. Which one of the following iron and steel plant is located neither on iron ore area nor on coalfield but approximately at the midway between them? [Chhattisgarh P.C.S. (Pre) 2018]

(a) Jamshedpur
(b) Bhadravati
(c) Durgapur
(d) Bokaro

Correct Answer: (a) Jamshedpur

Solution:Jamshedpur iron and steel plant is located almost in the middle of the two, not on the iron ore and coal fields. Domestic availability of raw materials such as iron ore and low-cost labour have fueled India's steel industry's growth. As a result, India's steel industry has been a major contributor to the country's manufacturing output. The Indian steel industry is cutting-edge, with cutting-edge steel mills. It has always aimed to keep older plants up to date and upgrade them to higher energy efficiency levels.

The iron and steel industry in India is divided into three categories:

primary producers
secondary producers
other major producers.

SAIL, TISCO, and RINL, India's main steel producers, had a combined capacity of around 50% of the country's total steel production capacity and production in 2004-05. ESSAR, ISPAT, and JVSL, the other major steel producers, account for roughly 20% of total steel production capacity.

17. TISCO plant is located near- [53 to 55th B.P.S.C. (Pre) 2011]

(a) Patna
(b) Darbhanga
(c) Dhanbad
(d) Tatanagar

20. Korba in Chhattisgarh has importance for- [U.P.U.D.A./L.D.A. (Pre) 2001, U.P.P.C.S. (Pre) 1994]

(a) Aluminium industry
(b) Copper
(c) Mica
(d) Steel

Correct Answer: (a) Aluminium industry

Solution:Bharat Aluminium Company Ltd. (BALCO) is located only 10 km far from the main township. That is why Korba district (Chhattisgarh) is significant for the aluminium industry. Aluminium is an important strategic metal for India's economy. After the iron and steel industry, aluminium is the second most important industry. Aluminium is used in the production and distribution of electricity in the modern world (it is a good conductor of electricity), household utensils and electric appliances, aircraft manufacturing, rail coaches, nuclear and defence accessories, and so on. It's also the fastest-growing metal, with nearly a 20-fold increase in the last 60 years (compared to 6 to 7 times for other metals). In the downstream sector, it created over 8 lakh jobs directly and indirectly, as well as over 4000 SMEs. In terms of the Bauxite reserve base, India ranks seventh in the world. Bauxite is the primary raw material used in the production of aluminium. The National Mineral Exploration Trust was set up to ensure an increase in aluminium production and to make the required volume of raw materials available to the industries.
