The biggest coal deposit by volume is the Powder River Basin in Wyoming and Montana, which the USGS estimated to have 1.07 trillion short tons of in-place coal resources, 162 billion short tons of recoverable coal resources, and 25 billion short tons of economic coal resources (also called reserves) in …
There are many varieties of coal in the world, ranging from brown coal or lignite to anthracite. The property that really sets coking coals apart from other coals is its caking ability, which is the specific property required in order to make coke suitable for steel making.
On average, about 630 kilograms of coke are required to produce 1 metric ton of steel. Production efficiency in the blast furnace process is highly dependent upon the quality of raw materials used. A blast furnace fed with high-quality coke will require less coke and flux, lowering production costs and resulting in a better hot metal.
