This paper reports on the effect of different parameters on Co separation from hot filter press cake (HFC) of
Cobalt from the national Iranian Lead and Zinc Company located in zanjan, Iran by two-step washing and
leaching with H2SO4. Hot filter press cake (HFC), contains 27.48 wt % Zn, 14.71 wt % Mn, 2.1 wt % Co, and
1.4 wt % Fe. Zinc was separated by water Washing and it was perceived that S/L ratio has not much to do with
Zinc recovery and zinc sulfate compositions were dissolved in less than 10 minutes. Co separation from HFC
was achieved by H2SO4 and it was observed that increasing in Temperature, dissolving time and sulfuric acid
concentration aids Co separation while on the other hand, pH increment and oxygen blowing influences
defectively on Co solubility.
