dc.description.abstractThe initial solution obtained from brine leaching of zinc ferrite cake is used to study the cementation process of lead, silver and copper. The optimum parameters of the brine leaching stage are: NaCl concentration of 250 g/l, H2SO4 concentration of 5 g/l, a temperature of 60oC, and a pulp density of 12.5 %. Two series of experiments are carried out using different cementation agents-iron and zinc powders. The effects of the cementation agent consumption, the temperature, the time and the solution initial pH on the cementation metals degree are investigated. The results obtained show that the cementation with a zinc powder leads to higher cementation degree of silver, lead and copper indicating that the repeated use of the pregnant solution aiming to leach new portions from the zinc ferrite cake is most probably favored.
