Abstract
There is thus provided a method allowing the recovery of metallic values from laterites by the action of rather diluted sulfuric acid on nickel and cobalt-bearing laterites, at atmospheric pressure and near ambient temperature, assisted by ultrasonic treatment. With an acid concentration in the range for example between about 25 and about 50 weight pcnt of sulfuric acid, under atmospheric pressure, sonication, extracting metallic values from the slurried laterites is thus achieved at room temperature.
