best combination of e-wastes to recover maximum amount of cu

In bioleaching process cyanidation of gold is difficult because of the ready formation of copper cyanide complexes# to solve this problem removing copper is considered in this study# six kinds of e-waste including mppcbs, cpcbs, tvpcbs, fpcbs, copcbs, and cpu was prepared# 31 experiments was designed and performed at 250 ml erlenmeyer flasks containing 100 ml solution with 10% inoculum, at 30 ℃ and 130 rpm# pulp density was adjusted at 15 g/l# after 20 days incubation the incubation was stopped and the recovered copper was analyzed using inductively coupled plasma optical emission spectroscopy (icp-oes)# the d-optimal mixture experimental design was conducted using a# ferrooxidans# the optimum portion suggested by the software for cpcbs, mppcbs, tvpcbs, copcbs, fpcbs, and cpu is 10%, 15%, 50%, 10%, 10%, and 5% respectively#
