Enhanced flotation of refractory gold ore by using sulfur-oil agglomeration with (NH4)(2)S2O3 as regulator in weak acidic pulp

摘要

In this study, a new approach "sulfur-oil agglomeration" for gold flotation was put forward to recover gold particles in laboratory and industrial scale experiments. The optimum recovery of gold was obtained by adding (NH4)(2)S2O3, oil emulsions and sulfur into the mill, together with butyl xanthate as the collector in weak acidic pulp adjusted by H2SO4.
