Congo (DRC) active magnesium oxide production process for nickel and cobalt, one-stage cobalt precipitation
Hebei Messi Biology Co., Ltd. stated that the impurity-removed liquid after preliminary purification reacts with magnesium oxide slurry under certain conditions to generate cobalt hydroxide precipitation, and the reaction is as follows: Mg(OH)2+CoSO4=Co(OH)2↓+MgSO4 In order to obtain high-grade cobalt hydroxide products and higher cobalt recovery rates, the use of active magnesium oxide conditions was tested […]
