The document discusses the recommended flowsheets for the electrolytic extraction of lead and zinc from the Umm-Gheig polymetallic ore in Egypt. It details the mineralogical and chemical analysis of the ore, along with hydrometallurgical treatment methods that include leaching and electrodeposition. The paper also evaluates the impact of various parameters on faradic current efficiency and compares different electro-deposition approaches.

- 3. lead and zinc extraction; flowsheet 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.
