Silica means the sand,.due to blasting,size of the sand would become very minute and it will cause silicosys (lung desease) to the human who is breathing the same..
So internationaly sand blasting has been banned...
However copper slag can be used for abrasive blasting..

Subject: [MW:7145] Copper Slag Abrasive
Hi everyone,
I came across many coating specs which are having one common sentence " Silica sand and copper slag shall not be used for blasting".
What is the issue with using copper slag ? What are the dis advantages of copper slag?
