Extraction of nickel and cobalt from nickeliferous

2017-10-10 · Nickel (Ni) is the twenty fourth most common element in the earth's crust; it naturally occurs as sulfides or laterites (oxides) (Crundwell et al., 2011, Kerfoot, 2000). Cobalt occurs in trace amount in laterite ores and it is often extracted as a by-product (Crundwell et al., 2011, Donaldson et al., 1986, Donaldson and Beyersmann, 2000).
