Dec 10, 2013 · By investigating the effect of above parameters on copper oxide recovery rate, the optimum condition for concentration, acid flow rate, size of ore and leaching time were found to be 40 g/l, 60 cm 3 /h, 1– mm and 10 days, respectively. Studies showed that the ammonia concentration and size of ore were more important parameters.
