Following the success at Broken Hill, mining companies throughout the world rapidly adopted the flotation process (Young et al. 2003). Flotation also used to split copper and nickel sulfides and separate them from iron sulfides and gangue minerals. Cobalt appears in the nickel concentration and the cobalt is subsequently recovered. Flotation has developed from the treatment of simple ores to the ever more .
