    Effect of Clay Rheology on Flotation of a Refractory Gold Ore

    Oct 10, 2016  The results showed that bentonite clay adversely affects floatability of pyrite while kaolinite clay had a lesser influence on flotation of pyrite. The addition of Ca2+ ions to the pulp containing bentonite modified the rheological characteristics and in turn improved the pyrite flotation.

    The amine oxide promoter need only be dispersible as a liquid or soluble in an aqueous bath in order to be in proper form for use in the flotation process. Thus, the promoter often will be in solvent for admission to the flotation process, conveniently at a 10%-30% actives (non-volatile solids) concentration.

    Jun 01, 2015  Six flotation tests were conducted using the copper–gold ore and its mixtures with quartz, clay minerals and gypsum. Fig. 1 shows the mass recovery as a function of water recovery from these tests. As can be seen, flotation of the ore or baseline resulted in a 5% mass recovery and 31% water recovery at the completion of flotation.
