Abstract
A method of continuously regenerating a metal containing acid solution enhanced with a salt-free material. The metal dissolved in a bulk metal containing acid solution is continuously oxidized by introducing a gas into a packed reaction vessel. The packed reaction vessel is in operative relationship with the bulk acid solution for recirculating regenerated solution and for receiving spent solution. The gas is introduced substantially cocurrently with the spent acid solution.
