	Calculations and computations are applied to find the optimal conditionts (pH, [NH3], ...) of a selective recovery of metal values from the electroplating sludges.



	This study compares a classical and approximate method, based on the superposition of solubility-pH-complex diagrams, and our rigorous approach, The studied example is the selective recovery of Ni++ and Cu++ from their hydroxide sludges by an ammoniacal leaching.



	We introduce also a direct relation between the solubility and the total concentration of NH3, [NH3]T
