Graphic element Exploiting ultra-pure quartz deposits in Northern Greece
     
 
This project identified quartz deposits in Northern Greece and produced high-purity silicon metal and ferrosilicon for high-tech applications through plasma smelting.
 

Northern mainland Greece is known to host numerous quartz vein deposits of extra high quality and with low impurities content. These very clean quartz sources can supply raw materials for the plasma smelting production of ultra-pure silicon metal and ferrosilicon. Plasma technology opens the possibility of lowering both operating and capital costs.

This project was aimed at identifying promising quartz deposits in Northern Greece, selecting appropriate processing methods and producing high-purity silicon metal and ferrosilicon through plasma smelting. Five deposits were selected, based on volume and compositional data. The selected quartz reserves guarantee continuity of product supply over a period of tens of years. A new processing plant was designed and constructed for producing quartz powders, and a new plasma furnace has been installed and is now operating in Greece.

Partners expect to be producing large amounts of ferrosilicon for high-tech applications in electronics and telecommunications shortly. Market research has helped to identify European and overseas ultra-pure quartz producers and end-users, particularly in the optical glass industry.
