Coal slag is a dark silicate produced as a byproduct of coal powered plants.
As an abrasive, coal slag is generally considered to be one safe option to using non-recyclable industrial blasting media. The different angular shapes of individual coal slag particles make it ideal for efficient removal of rust or paint coatings from steel and other metals in preparation for painting. Coal Slag abrasive is mostly used in both new steel and steel maintenance applications including blasting of storage tanks, water towers, bridges, ships, and oil refinery maintenance.
