Silica Sand

Unlike construction sands, those minerals are searched for their compositions and characteristics which receive process of washing - drying - grinding - sieving - dusting for industry use.
However their numerous qualities remain irreplaceable for many uses such as :
- Filtration and waters process
- Sports grounds
- Draining agents

But also for the following specific industries :

- Silica glass sand
- Flat glass used in the construction or the windscreens remains the most important in the using sector.
- Packing glass which gathers the whole manufacturing of bottles, jars, flasks...
- Crystal glassworks, high-end product ,such as the bottling in perfumery using sands with very low iron content.
-  Extra-clear glass and solar glass (photovotaic panels and solar panels).

- Industrial sand
- Loads in the resins, plastic paints, polymers, rubber, mastics and glues.
- Facade coating.

- Foundry sand
Essential for moulds' preparation which concerns two foundry's sectors :
1. The sand plant sector which stores, prepares mixings for the sand moulding workshop.
2. The core making sector in the big foundries for the preparation of the combination sand + resin + catalyst.
