  • Pyrite Flotation Froth Flotation (Sulphide & Oxide

    If I understand correctly you are working on a refractory gold ore with the gold being refractory because it is 'locked' in the pyrite The normal options considered for this type of gold deposit are: Make a sulphide concentrate by flotation then oxidize the sulphides by autoclaving, roasting or ultrafine grinding and atmospheric oxidationsulphide ore the galena can be floated first at higher using cyanide to prevent sphalerite and pyrite from floating Then activation of sphalerite with copper sulphate and high pH to depress pyrite enables a sphalerite concentrate to be made Finally a lowering of pH can enable a pyrite concentrate to be made if requiredCHAPTER 7 FLOTATION OF SULPHIDE MINERALS

  • Optimisation of gold recovery by selective gold flotation

    Optimisation of gold recovery by selective gold flotation for coppergoldpyrite ores Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free Compared to the flotation of a clean gold orePyrrhotite floats best in acid circuits The pH range for flotation for gold sulfide ores containing pyrite and arsenopyrite is generally between 7 and 9 Flotation may be carried out at higher pH values of 9 to 10, since this favours the depression of talc minerals and avoids the use of expensive gangue depressantsFlotation of gold and goldbearing ores ScienceDirect

  • Rcovery of gold in pyritic ores Mine

    Gravity concentration tends to recover the pyrite with the gold, and only removes the lighter minerals, such as quartz, from the ore The most difficult particles to gravity concentrate are the fines, and 75 microns to 2 microns are definitely very fine So, even if the ore were ground to 2 microns, it may not be recoverable using currentgold >pyrite >chalcopyrite >galena This follows the same order of minerals electrochemical activity From noble to active is pyrite, chalcopyrite, galena and sphalerite The activity of galena for oxygen reduction is less than that of the noble metals and chalcopyrite and pyrite Lower Eh values were observed with galena by Rand and WoodsE ect of pH on Pulp Potential and Sulphide Mineral
