The iron industry began to relocate to coal fields, which usually had iron ore nearby. Developments elsewhere also helped to boost iron by stimulating demand, such as the increase in steam engines which needed iron, which in turn boosted iron innovations as one industry bred new ideas elsewhere.
The first process that most of the ores or minerals undergo after they leave any mine, is mineral processing or mineral ore dressing. It is a process of ore preparation, milling, and ore dressing ...
This concentrated ore is mixed with limestone CaCO 3 and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs. The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag.
Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 99.99 pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...

2016-5-52.1 Iron Ore Composition Iron very rarely occurs in the earths surface as a metal. It is widely distributed, combined with oxygen as iron oxides. In fact it is believed that iron makes up about 5 by weight of the earths crust. Geologists recognise various types of iron ore, classified chiefly according to iron Fe content see Table 1 below.
Originally, the iron was collected in pools called pigs, which is the origin of the name pig iron.
