...ecological refining of mineral RawMaterials

Foundries

Mouldings for the foundry industry: From the quartz sands in conjunction with special binders, the negative moulds are produced, which are then later filled with liquid metal. Low quality of locally available raw materials increases the costs for high quality imported sand.

Demand
Locally available raw material containing: Al2O3 = 0,12%; Fe2O3 = 0,06 %; SiO2 = 99,7 %.

Solution
Local supplier of high quality silica sand.
