摘要：

Hydrometallurgical processing of low grade chromite (Barramiya, Egypt) is attained through leaching with sodium hydroxide of mechanically activated chromite ores under relatively high temperature (240 degrees C) in the presence of oxygen pressure (10 bar), The effects of temperature, grinding time, leaching time acid oxygen partial pressure on chromium extraction were studied, The residual black sludge has a high iron content and nearly negligible chromium and sodium contents, which minimize disposal problems.
