  • Copper smelter slag treatment by ammonia solution:

    The feasibility of copper smelter slag processing by ammonia solution treatment was investigated. The central composite rotatable design (CCRD) and approximation method were used to determine the optimum conditions of zinc and copper recovery to a solution. The experimental design was done at five levels of the four operating parameters which were the initial concentration of NH3, the initial
