ABSTRACT
Hydrometallurgical processing of zircon concentrate separated from Egyptian black sands is attained through leaching with sodium hydroxide of mechanically pretreated zircon concentrate under relatively high temperature (260oC). The effects of temperature, sodium hydroxide concentration, grinding time, grain size, and leaching time were studied as well as the kinetics of the leaching process.
