Coal Slag Abrasive with Blastox for Lead Remediation

Coal slag is a glass matrix alumina-silicate which is produced as a by-product of coal burning power plants. As the coal burns, the residual ash (slag) becomes molten. When this slag is cooled, it vitrifies into a glassy, abrasive material, which is then crushed to produce blast media. A wide range of mesh sizes are available, with some being capable of removing very thick or …

Coal & steel

Steel is an essential material for modern life and global steel production is dependent on coal - 70% of steel produced uses coal. Metallurgical coal – or coking coal – is a vital ingredient in the steel making process. Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The coking coal is crushed and washed.
