graphite carbon removal flotation copper
Effect of carbon on Cu/Pb/Zn flotation. - Froth… A potential approach would be to flash float the graphite to remove it at a size as coarse as possible and then approach the sulphide flotation conventionally. The trick would be to find a suitable process to clean the flash graphite concentrate so as to minimize the values associated with it.read more
