COAL SLAG Blastline Group

Coal Slag is a boiler slag, which is a recycled product from coal burning plants. When coal is fired at over 2500 degrees, it melts and produces a by-product called slag. When is slag is cooled through a process called vitrification, it crystallizes, forming sharp, angular granules in a variety of sizes.

But in the new process, instead of simply turning coal to metal, they’re turning the slAG to a process called metallurgical slag processing. That process converts the slags to a more durable material called chromite, which can be used in steel.
