Exploring of cobalt and nickel cementation from zinc-sulphate and aqueous solutions with various quantity of copper and antimony activators is developed. Middle speeds of process behavior of impurities cementation and hydrogen evolution and also apparent activation energies are calculated. If the dosage of copper and antimony activators increases, the apparent activation energies of cobalt, nickel and hydrogen reduction decrease, what correlates with fundamentals of catalytic processes.

Cementation, cobalt, nickel, activators, copper, antimony, kinetics, apparent activation energy.
