2020-8-25 Cobalt. Cobalt (Co) is a transition metal with an atomic weight of 58.93 and an atomic number of 27, right in between iron and nickel. Cobalt, however, is not as abundant as iron and only makes up of about 0.0020% of the Earth’s crust. This makes cobalt a little more rare and valuable than the other members of the triad because it is still ...

RSM Abstract Due to the decreasing production of nickel and cobalt from sulfide sources, the Ni and Co extraction from the oxide ores (laterites) have become more prevalent. In this research work, the effects of calcination prior to leaching, acid concentration, percent solid, pH, and stirring speed on the nickel and cobalt recoveries from an iron-rich laterite ore sample were investigated ...

2010-5-29 It is absolutely correct. But the metals such as Mn, Cu, Al, Cr also possess unpaired electrons know. Mn has 5 unpaired electrons, Cr has 6, 1 from ‘s’ orbital and the other 5 from ‘d’ orbital, Al and Cu each possess 1 unpaired electron. But iron has 4 unpaired electrons, nickel has 2 and cobalt has 3 unpaired electrons each.
