摘要：

Hydrometallurgical processing of ilmenite concentrate separated from Egyptian black sands is attained through leaching with sodium hydroxide of mechanically activated ilmenite concentrate under relatively high temperature (200 degreesC) in the presence of oxygen. pressure (6 bar). The effects of temperature, sodium hydroxide concentration, grinding time and oxygen partial pressure on titanium extraction were studied as well as the kinetics of the leaching process.
