At the surface, the ore is subjected to additional crushing and fine grinding. A flotation process is used to separate the silver-bearing galena and tetrahedrite from other ore minerals and waste rock particles (tailings) to form mineral concentrates. Development of the flotation process occurred in the early days of mining at Broken Hill.
