This document discusses several manufacturing industries in India including steel, aluminum, chemicals, cement, and automobiles. It provides details on the steel industry such as reasons for low per capita steel consumption. For aluminum smelting, it describes the process and explains that transporting aluminum would be more expensive than plastic due to its higher weight. The document asks questions about the relative costs of transporting raw materials versus finished products. It also discusses factors to consider when locating cement manufacturing units.

3. IRON AND STEEL INDUSTRY

5. PROCESSES OF MANUFACTURE OF STEEL

8. Why is the per capita consumption of steel so
low in India?
Because of the following reasons:
● Per capita income is very low in India.
● Living standard is very low.
● Durable substitute of Steel are available at
very low prices and they are also very light
weight.

11. ALUMINIUM SMELTING

13. PROCESS OF MANUFACTURING IN ALUMINIUM INDUSTRY

14. A factory produces aluminium saucepans with plastic handles. It
obtains aluminium from a smelter and a plastic component from
another factory. All the manufactured saucepans are sent to a
warehouse:
a) Which raw material is likely to be most expensive to
transport and why?
Aluminium, because it is heavier than plastic.
a) Which raw material is likely to be the cheapest to
transport and why?
Plastic, because it is light in weight.

15. Do you think the cost of transporting the
finished products after packaging is likely to be
cheaper or more expensive than the cost of
transporting aluminium and plastic? Why?
● They will occupy more space.
● The finished products need delicate care. There for
transporting them need extra cost in their packaging.
● The finished products have to be sent to different
destinations.

16. CHEMICAL INDUSTRIES

17. TWO TYPES OF CHEMICAL INDUSTRIES

18. CHEMICAL INDUSTRIES

21. CEMENT INDUSTRY

22. Where would it be economically viable to set up
the cement manufacturing units?
● The units should be set up close to raw material
because this industry requires bulky and heavy raw
material.
● The place should have continuous supply of electric
power.
● The place should have efficient network of railway
and transport.

23. Find out where the cement plants are located in
other states in India. Find their names.

24. AUTOMOBILE INDUSTRY
