Abstract
SUMMARY
A new cementation reactor was developed and its performance was studied. The reactor consists of an array of pulsation horizontal perforated discs made of zinc upon which Cu ++ was cemented from CUS04 solution.
Many variables were studied such as: frequency and amplitude of pulsation, initial concentration of CUS04, disc separation, disc diameter and temperature.
The results have shown that the suggested reactor is highly effective in conducting cementation reaction by virtue of the high rate of mass transfer resulting from the high intensity turbulence induced by disc pulsation. Activation energy determination revealed that cementation in the suggested reactor takes place through a mixed control mechanism (Le.; the reaction is partially diffusion controlled).
