Copper Slag
The majore use of Copper slag is a blast cleaning medium, but other uses include its application as roofing granules, as an additive for ceramics, and as an aggregate for asphault coatings. Abrasive applications are primarily for etching and cleaning of new steel as well as removal of rust and milli-scale. Blasting applications include all-field installations, sophisticated fabrication yards, pipelines and oil storage tank internals and externals.
