Abstract

Electrochemical removal of gangue surrounding metallic elements in bulk material is carried out by: (a) loading the bulk material into a basket in an electrolysis cell comprising a cathode, formed by a central conductive part extending into the basket and connected to a metallic grid at the bottom of the basket, an anode outside the basket and an aq. basic bath as electrolyte; (b) maintaining cathodic polarisation to evolve hydrogen and detach the gangue; (c) removing the basket from the cell; and (d) separating the metallic elements from the gangue.
