or chlorine was involved to recover nickel from nickel oxide ore [11-12]. Chloridizing segregation by MgCl2 and magnetic separation of low-grade nickel laterites was used to recover nickel and cobalt from low-grade laterites [13]. Segregation roasting by using NaCl alone or with CaF2, CaCO3 or Ca(OH)2 was involved to recover nickel from nickel oxide ore or deep sea nodules [14-15]. In addition......
processes, were usually focused on the utilization of nickel in laterite ore, and more attention was paid to the recovery of nickel than that of cobalt. In fact, cobalt recovery provided an important revenue... from limonite-type laterite ores due to its low reactivity with goethite, in which nickel was involved[6-7]. In this work, extraction of cobalt from limonite-type laterite ores was studied by citric......
