million tonnes of metallurgical coal exports globally. • About 30% of coal can be saved by injecting fine coal particles into the blast furnace, a technology called Pulverised Coal Injection (PCI).10One tonne of PCI coal used for steel production displaces about 1.4 tonnes of coking coal. Coals used for pulverised coal injection into blast

By the 1990s coal use became the norm. Typically coal preparation involves drying and grinding coal to tiny particles of less than 1mm for injection. The coal particles are separated from released gases in a cyclone. The waste gas, and sometimes natural gas, can be used for drying additional coal, which is generally kept below 6% moisture content.
