Improved recovery of a low grade refractory gold ore using

In this work, different flotationpreoxidationcyanidation methods are considered for treating a low grade refractory gold ore. On the one hand, the results of selective flotation show that 22% and 31.1% of total Sb and As, respectively, remained in the final tailings and only about 28% of the total Au remained for further cyanidation processes.
