Abstract

Aquí así se proporciona un método que permite la recuperación de valores metálicos a partir de lateritas por la acción del ácido sulfúrico bastante diluido en lateritas que portan níquel y cobalto, a presión atmosférica y temperatura casi ambiental, asistido por el tratamiento ultrasónico. Con una concentración de acido en el intervalo por ejemplo entre aproximadamente 25 y aproximadamente 50% de ácido sulfúrico, bajo presión atmosférica, sonicación, extrayendo los valores metálicos a partir de lateritas suspendidas se logra así a temperatura ambiente.Here a method is provided that allows the recovery of metal values from laterites by the action of sulfuric acid quite diluted in laterites carrying nickel and cobalt, at atmospheric pressure and near ambient temperature, assisted by ultrasonic treatment. With a concentration of acid in the range for example between about 25 and about 50% sulfuric acid, under atmospheric pressure, sonication, extracting the metallic values from suspended laterites is thus achieved at room temperature.
