Year after year, the sediments of the Tigris River in Iraq are increasing,causing the river clogs, which requires the removal of these sediments from timeto time. Unfortunately, they do not benefit from these deposits, although theycontain high levels of silica, which concentrations were between 59 - 66%. Purealuminum powder mixed with sediments at different ratio (1:1, 1.5:1 and 2:1)sediments/aluminum. The reducing temperatures were 900, 950 and 1000 °C.leaching process was used to purified the silica. This process was carried outby using different concentrations (3,4 and 5)M of sulfuric acid to obtainsilicon element. The purity of produced silicon reached to 98. 9%. with ofextraction efficiency more than (88%).
