Mineral Based Industries Flashcards
define mineral based industries
those industries which use minerals as raw materials and are major components for growth and industrial development
why does iron and steel industry form the backbone of other industries
provides raw material for making industrial machinery, electrical machinery, defence equipment, railway tracks, railway engines, bridges, dams, shops, automobiles, etc
first attemt to produce iron and steel on modern lines
in 1830 at Porto Novo (TN)
first unit which was able to produce pig iron successfully
Kulti, in 1874 (Bengal Iron Work Company)
where is tata iron and steel company
at Sakchi (now Jamshedpur) in 1907
main raw materials used in iron and steel industry
iron ore, coal, manganese, limestonee, chromate, feldspar, scrap iron, flux
processes used for converting iron ore to steel
- ore reduction
- steel melting furnaces
- rolling mills
flux
limestone and dolomite, to help combine impurities in the ore as slag
pure iron
pig iron
use of deoxidation
to convert pig iron to steel
integrated steel plant
all processes from providing raw materials, basic fuels, water, to conversion of steel, rolling, are done at one place
mini steel plant
electric furnaces and do not have all the facilities at one place and require separate units for completing the process of steel manufacturing
largest steel making company in public sector
Steel Authority of India (Bhilai, Durgapur, Rourkela, Bokaro, Burnpur_
owns ferro alloy plant at Chandrapur in Maharashtra
largest steel company in private sector
Tata Iron and Steel plant at jamshedpur
where does TISCO obtain its coal
Jharia and Bokaro coalfields
