The main objective is to optimize the reagent suite in the lead flotation circuit, thus improving the flotation selectivity between galena and sphalerite. The optimization of the reagentOptimisation of gold recovery by selective gold ,2001-2-1 · Optimisation of gold recovery by selective gold flotation 231 S-701 was shown to give optimal recovery in an acid float, at an approximate pH of 4.5. S-701 could be used to recover the majority of the pyrite associated gold and then with either xanthate or one of the other new collectors (e.g. F-100) the copper could be recovered at the basic pH.

  • Optimisation of gold recovery by selective gold

    Copper sulphides are selectively floated from pyrite ores at high pH's in excess of 11. It is less clear how the free gold behaves under these conditions. In addition, for extra gold recovery, further collectors are added, such as the monothiophosphates, which are known to be selective gold collectors.Optimisation of the selective flotation of galena and,2006-5-16 · A flowsheet has been proposed to improve selectivity between galena and sphalerite in the lead flotation circuit. It includes the regrinding of the lead rougher concentrate prior to the cleaning stage due to poor liberation between galena and sphalerite.
