    Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines Manual mining method is normally limited to float ores and smallIron ore is the primary raw material used to make steel Steel is strong, longlasting and costefficient – making it perfect for everything from washing machines to cars, bridges and skyscrapers According to the World Steel Association, steel is the most commonly used alloy in the world Global steel consumption is forecast to grow by 1%2%Iron ore Rio TintoIn Kudremukh area of Chikamagalur district, iron ore mining is done using the open cast method Magnetite, which is the ore variety in Kudremukh, is of low grade having iron concentration to the tune of 33 to 38 percent resulting in generation of more waste (62 to 67 percent of the total ore mined) Out of 4605 hectares of mine leaseMINING AND QUARRYING
