    Flotation will frequently be used when gold is recovered in conjunction with other metals such as copper, lead, or zinc. Flotation concentrates are usually sent to an off-site smelting facility for recovery of gold and base metals. Cyanide leaching is frequently used in conjunction with flotation. Cyanidation

    Jul 01, 2014 · Abstract. In this work, different flotation–preoxidation–cyanidation 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

    Francisco Carranza. INTRODUCTION RefractorinessGold ores are considered refractory if gold extractions from a conventional cyanidation process are less than 80% even after fine grinding [ 1 ]. These low extractions do not normally allow economic recovery of the metal [2] [3] [4] [5] [6].These resources can consist of ores, flotation concentrates, mill railings and other reserves

    Extraction from refractory ores. Many gold-bearing ores and concentrates are not readily amenable to cyanidation, owing to the presence of substances that consume the cyanide reagent before it can dissolve the gold, preferentially adsorb the gold as it dissolves (a phenomenon called preg-robbing), or completely surround the gold particles in such a way as to prevent access by the cyanide leach …
