Today, it is estimated that the global steel industry used about 2 billion tonnes of iron ore, 1 billion tonnes of metallurgical coal and 575 million tonnes of recycled steel to produce about 1.7 billion tonnes of crude steel. Recycled steel sometimes called scrap steel is one of the industrys most important raw materials.
Coal and coke Coking coal is a key raw material in steel production. As iron occurs only as iron oxides in the earths crust, the ores must be converted, or reduced, using carbon. The primary source of this carbon is coking coal. Coke, made by carburising coking coal i.e. heating in the absence of oxygen at high
Bituminous coal is used to generate electricity and is an important fuel and raw material for the steel and iron industries. West Virginia, Kentucky, and Pennsylvania are the largest producers of bituminous coal. Anthracitecontains 86-97 percent carbon, and has a heating value slightly lower than bituminous coal.
Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The coking coal is crushed and washed. It is then purified or carbonised in a series of coke ovens, known as batteries, where the coking coal is heated to 1000-1100 C in the absence of oxygen for 12-36 hours.

Carry out polymerization reactions. Process the polymers into final polymer resins. Produce finished products. First, they must start with various raw materials that make up the monomers.
Sep 29, 2014 Coke making. The main solid wastes generated in the production of metallurgical coke are coal dust, coke dust, tar sludge and acid sludge. Coal dust is recycled back through the coal blend. Coal dust can also be recycled along with coke dust by adding them in the sinter charge mix. Tar sludge is added to the coal blend to improve its density.
Jul 26, 2019 Iron was one of the most basic requirements of the rapidly industrializing British economy, and the country certainly had plenty of raw materials. However, in 1700, the iron industry was not efficient and most iron was imported into Britain. By 1800, after technical developments, the iron industry was a net exporter.
