Technology of recovery of associated gold from Siberian

Up to12%cash back· 1. Skarnmagnetite ores of Siberia and wastes (rejects) of their treatment are a potential source of gold and other precious components. Skarnmagnetite mineral associations, in particular, are characterized by low gold contents (hundredths of 1 g/ton). Higher contents of noble metals are associated with superposed sulfide and quartzvein mineralization (tenths of 1 g/ton and less).

Invisible and microscopic gold in pyrite Methods and new

Au speciation in sulfides (including "invisible" Au), which mostly controls the loss of Au during ore dressing, is discussed. Modern methods of analysis of Au speciation, with discussion of limitations by locality and sensitivity, are reviewed. The results of sulfide investigation by the methods of scanning and transmission electron microscopy, mass spectrometric analysis with laser ablation

Leangrade refractory sulfidic gold ores containing 12 g/ton of gold, which cannot be economically processed through conventional processes (e.g., Heap bioleaching of Carlin ores). 2. Refractory sulfide concentrates, where finely disseminated gold particles are locked up, making them uneconomical for direct cyanidation (e.g., Bioreactors BioxOutotec, BacTech, BIONORD).

Gold extraction

A "refractory" gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pretreatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally contains sulfide minerals, organic carbon,

Gold Ore an overview ScienceDirect Topics

A typical arsenical gold ore contains arsenopyrite as the major arsenic mineral. However, some arsenical gold ores, such as those from Nevada in the USA (Getchel deposit), contain realgar and orpiment as the major arsenicbearing minerals. Pyrite, if present in an arsenical gold ore, may contain some gold as minute inclusions.
