Abstract
Cobalt acetate solution is produced by flowing a circulating oxygen-containing stream of dilute acetic acid solution containing initially about 20% free acid through a bed of cobalt chips and adding dilute acetic acid solution and introducing additional oxygen into the circulating stream in replenishment of those reactants as the dissolution reaction proceeds.
