Silica Sand
In Egypt there are two main locations of high quility silica sand 1st, Zafrana – red sea and the 2nd, north and south Sinai ,
The reseves in Zafrana area and Sinai are over thousands milion ton of high quality silica sand .
which supply the glass industries , paints , foundries , chemicals and ceramics.
Silica sand for glass, Silica sand for crystal, Silica sand for foundry,
Silica sand for painting, Silica Sand for oil and gas ,Silica Sand for Stamped concrete ,Silica Sand for water filtration ,
Silica Sand for golf Course, Silica Sand for water treatment, Silica sand for plastering ,
Silica Sand for sand plastering and for many uses.etc more details..
