| Abstract | ||
| In this research a preliminary beneficiation study was conducted on a sample from Ardhuma silica-sand deposit in the Iraqi Western Desert, to provide a raw material for silicon industries. The beneficiation processes applied were vibration screening (dry and wet), attrition scrubbing and magnetic separation (dry and wet). These techniques were used individually or in combination to upgrade the sand to produce quartz-sand meeting the requirements of Metallurgical-Silicon production. This would be the base material for silicon materials and Solar-Grade Silicon. Quartz-sand fulfills the requirements of the State Company for Mining Industries and Aquatic Insulation for the raw materials of MG-Silicon production, which was produced by applying one of the following beneficiation routs: The first consists of autogenesis grinding, dry screening on 150 µ, attrition scrubbing and wet screening on 150 µ. Whereas, the second includes autogenous grinding, dry screening on 150 µ and dry magnetic separation using magnetic field intensity of 16.5 Kilogauss. | ||
