Copper slag or Ebonygrit is an abrasive blasting grit made of granulated slag from metal smelting processes (also called iron silicate). Copper slag abrasive is suitable for blast cleaning of steel and stone/concrete surfaces, removal of mill scale, rust, old paint, dirt etc. Ebonygrit is a disposable high-density blasting slag made from a by-product of copper production. Ebonygrit distinguishes from light-weight blasting slag, due to its high density property. Typically, the majority of its composition is iron oxide and silicon dioxide, formed when molten slag is quenched in cold water.
