Oct 31 2020 Gold extraction of 75 was obtained under ambient conditions of temperature. Moreover the overall process achieved about 65–67 Au recovery this being in line with the conventional cyanidation process. As these results are obtained by application of the thiosulfate process on a low gold content ore they may be considered encouraging.
Nov 07 2013 Abstract. This paper describes an approach to externalising and formalising expert knowledge involved in the design and evaluation of hydrometallurgical process chains for gold ore treatment. The objective of this knowledge formalisation effort is to create a case-based reasoning application for recommending a treatment process of gold ores.

Ore Grinding Stage The grinding operation usually adopts one or two ball mills with types of lattice and overflow. The second stage grinding operation forms a closed circuit with a spiral classifier or a hydro cyclone.
A contribution to documenting current and future best practice in gold ore processing seems timely. The focus of this volume is on advances in current gold plant operation from conception to closure; chapters also cover innovations at the bench and pilot-scale level that would be expected to find commercial application at some stage.
