Abstract
This study was carried out to determine the possibility of reducing the iron oxide ratio in silica sand from Ardhumah, an area, (18) km west of Rutba, a city in Al-Anbar Governorate, to obtain sand specifications appropriate for making colorless glasses (not exceeding 0.02 % iron oxide ratio). The reduction process of iron oxide includes three stages; the first stage is magnetic separation to reduce Fe2O3 from 0.092% to 0.040%, the second stage is re-floatation which has reduced Fe2O3 to 0.024%, finally treatment of the sand output from the first and second stage with diluted HCl or H2SO4, this study showed the possibility of obtaining silica sand with a ratio of Fe2O3 up to 0.016%.
