What is Coal Slag? | Frequently Asked Questions | US Minerals

This stuff is 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 the slag is cooled through a process called vitrification, it crystallizes, forming sharp, angular granules in a variety of sizes. We reclaim this slag and put it ...
