Copper Slag

Product Description and Technical Data:Copper Slag

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.

Copper Slag

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.
