Raw materials for iron making
WebModern iron making. Iron is manufactured in a blast furnace. First, iron ore is mixed with coke and heated to form an iron-rich clinker called ‘sinter’. Sintering is an important part of the overall process as it reduces waste and provides an efficient raw material for iron making. Coke is produced from carefully selected grades of coal. WebJul 23, 2013 · Coke constitutes the major portion of iron-making cost and its production causes severe environmental concerns. In addition, lower energy consumption, lower CO 2 emission and waste recycling are driving the Iron and steel making industry to develop “coke free, zero waste or green processes”. In the present article, an overview of possible ways …
