Frequently Asked Questions | FAQ | Black Diamond Abrasives

What is copper slag (aka iron silicate)? Copper slag (aka iron silicate) is a by-product of a metal refining process. During smelting, slag floats on the molten metal. Slag that is quenched in water produces angular granules that are stockpiled to be processed into granules for a variety of our blasting abrasives.

Copper Slag

Copper Slag is by-product or waste stream from the production of copper. The smelting process produces a glass like substance that will settle on the top of the melting copper and is basically the non-copper impurities being separated. The slag is then skimmed off the melted copper and delivered to a "slag heap" or slag dump where it is left to cool.
