open cast iron ore mining processes involved

Iron ore is obtained in the conventional method of open cast or underground mining and conveying the ore to the surface preparation are where it is crushed washed and transported to the smelter Here the ore is put into a blast furnace along with limestone and coke and subjected to hot air blasting and heat which converts the ore to molten iron

Iron ores are rocks and mineral deposits from which clanging iron can be reasonably extracted Iron ore mining is classified into two categories manual mining and mechanized mining methods Haematite and magnetite are the most commonly found iron ore minerals Deposits of iron ore such as haematite containing iron oxide are found in sedimentary rocks from which the oxygen is removed from the

Cast iron has already been mentioned above This section deals with the types of iron and steel which are produced as a result of the steelmaking process Wrought iron If all the carbon is removed from the iron to give high purity iron it is known as wrought iron Wrought iron is quite soft and easily worked and has little structural strength

Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 9999 pure copper called cathodes which will ultimately be made into products for everyday most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different

Openpit mining or opencast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow This form of mining differs from extractive methods that require tunneling into the earth such as long wall mining Openpit mines are used when deposits of commercially useful minerals or rocks are found near the surface that is
