addition of copper as an activator improved only the recovery of silver. the recovery of ag and au seems to depend mutually on the flotation response of the carrier sulphide minerals since a good correlation between gold and iron recoveries and between silver and antimony/lead recoveries.
froth flotation is a mineral concentration process used to recover a vast array of the objective of passing through the rougher and scavenger flotation circuits pyrite gold recovery in copper rougher flotation tailings. gold in copper rougher flotation tailings (0.07% cu. 0.61g/t au tail grades).
flotation of antimony ore clementinaworks.co.za. in spite of the lack of basic research on flotation of goldbearing ores the flotation technique is used not only for upgrading of lowgrade gold ore for furth. contact supplier antimony processing equipmentantimony ore flotation method antimony ore handselected methods.
the froth flotation method is widely used to treat various veins of gold and silver ores for the following reasons: (1) in most cases the froth flotation process can enrich gold and silver in sulfide concentrate to the greatest extent and discard a large number of tailings thus reducing the smelting cost.
froth flotation (sulphide & oxide) your flotation tests (70% gold recovery vs. 33% antimony recovery) are compatible with my deposit - it was no problem to produce quality mono mineral sb-concentrate (52-53%) but gold was extra because older mineralization stage was pyrite-arsenopyrite one with gold and younger mineralization stage was
