摘要

Cementation equilibria, in presence of the complexing ligands of the L~- or L~0 type, have been discussed. Equations expressing dependence of the equilibrium concentration c_A* on the process parameters are presented. They indicate that in the cyanide or ammonia complexes solutions, dependently on the reacting metal pair, c_A* may rise, decline or remain unchanged-when the concentration of the complexing compound increases.Equilibria concentrations c_A* are several ranges of value higher than those c_A**, reached in absence of complexes. Solely in the case of the Ag~+/Cu system a reverse dependence may
