Mill Tailings Storage for Reprocessing in Future

Apr 22, 2017· To retreat 15 or 20 millions of tons of unsegregated tailings in which a large portion carries only 0.12 to 0.15 per cent., is no easy problem for the future metallurgist. There are many milling plants that treat complex ores which carry lead, zinc and copper, and it is not possible to make a satisfactory extraction from all of these values.
