| Abstract | ||
| Serpentenite ore is one of the Iraqi ores in the Benjwen city in the north of Iraq, it contains of (33.62%) Magnesium and (35.62%) Silica, and (6.1%) of magnetite, and its specific gravity was (0.760). The photographic film by the (XRD) shows that the mineral ore was Olivine, Cresotyle, Anthersite, and Magnetite, so from that the research idea arose in concentrate of the magnesium from the Iraqi serpentenite ore to invest it locally and with economic way by using concentrated sulfuric acid for solving the magnesium in the ore in the form of magnesium Sulfate after separating the magnetite by wet magnetic separation and after that solved by the sulfuric acid and by different temperatures, and concentrated acids and times from the results that the best temperature of the pulp is in the boiling temperature(100) oC and in 40% concentrate of sulfuric acid and the solvent time is two hour and solid liquid 1:3 so the grade of magnesium was 91.5% and the recovery was 93.6% | ||
