Oxidative leaching of refractory sulphidic gold tailings

Sep 01, 2020 The gold extraction from the refractory sulphidic gold tailing by [Bmim + HSO 4− ]-water solution 20% (v/v)/thiourea/ferric ion was conducted at longer extraction times of 1 day, 2 days, 3 days and 5 days at pH = 1, temperature 60 C and shaking speed of 250 rpm. Fig. 3 demonstrates the gold extraction at longer leaching times.

Leaching of a polymetal gold ore and reducing cyanide

Mar 15, 2021 Many aspects of gold ores leaching by glycine (C 2 H 5 NO 2) and glycine-cyanide solutions are still not well understood.The base-metal components have been shown to have a strong impact on gold leaching kinetics. In this research, with the aim of reducing cyanide consumption, leaching of a polymetal (Pb-Cu-Zn) gold ore using a synergistic lixiviant mixture …
