Abstract
The polymetal complex ore Umm-Gheig considered in Egypt as a rather rich source of lead and zinc is subjected to
mineralogical, chemical, spectral, X-ray and differential thermal analyses. Hydrometallurgical treatments based on leaching,
precipitation and electrodeposition of metal from the ore are established. The influences of current density, temperature and metal
ion concentration on the Faradic current efficiency are discussed. Advantages and disadvantages of flowsheets and various
approaches depending on convenient baths for the electro-deposition of metals are investigated. The results of electron
microscopic investigation confirmed by metal value data given in the A.S.T.M. cards coincide well with those given by chemical
analysis.
