Following the success at Broken Hill, mining companies throughout the world rapidly adopted the flotation process. A similar situation to that at Broken Hill existed at the massive copper ore-body in Bingham Canyon in Utah, USA, where mining had exhausted the overlaying high-grade oxide ore by the end of late 19th century. The introduction of flotation in the early 20th century allowed the huge underlying low-grade copper sulfide mineralization to be processed economically.
