JetBlast™ Copper Slag is a by-product produced in the manufacture of copper. During the smelting and quenching process, in the copper smelter, mineral slag is converted to Iron Silicate, thus producing raw copper slag. The raw copper slag is then processed at up to 90 tonnes per hour, to produce JetBlast™. JetBlast™ is produced from 100% raw copper slag and is not mixed with recycled copper slag or tin slag. Additions of either of these two products can significantly increase levels of Radioactivity and Conductivity.
JetBlast™ is a low cost expendable material suited for open blast cleaning and due to its low silica content does not pose the health hazards created by silica sand. Its sharp, hard cutting edges provide a fast cleaning action and excellent surface profile preparation. JetBlast™ is one of the most economical expendable abrasives available for cleaning steel surfaces where recovery and reuse are not practical.
Coarse grade JetBlast™ is used predominantly in shipyards for the removal of heavy corrosion and coatings leaving a typical surface profile of up to 120 microns. Medium grade JetBlast™ is used for cleaning mill scale and medium rust removal, creating a typical surface profile of 60 to 100 microns. Fine grade JetBlast™ is used on new steel to remove mill scale and light rust resulting in a typical surface profile of 40 microns. For low-end applications, where blasting cost is a major factor, a general grade material is available.
