Gold Process Mineralogy - SGS

Based on the gold recovery and mineral processing techniques required, gold ores are commonly classified into two major ores. Typically, free-milling ores are defined as those where over 90% of gold can be recovered by conventional cyanide leaching. Refractory ores give low gold recoveries only with the use of significantly more reagents or more complex pre-treatment process.1

Processing technologies for gold-telluride ores

2016-9-12  The presence of gold telluride minerals may render an ore refractory, the extent of this depends on the telluride mineral present and the mineralogical association [3]. Gold, silver, and gold/silver-telluride minerals in ores dissolve more slowly than native gold in cyanide solutions, which results in less efficient gold extraction [4].
