The technological processing flowsheet for gold-bearing ores varies widely. The choice of a particular technological flowsheet depends on several factors, including the nature of the gold in the ore, especially its size and chemical composition, the nature of the minerals associated with the gold, the presence of other valuable components in the ore, and the …

Statistical analysis of the effects of process parameters on dissolution of gold in glycine media revealed that temperature and pH have significant impact on the amount of gold dissolved from the ore, while the influence of glycine concentration is surprisingly negligible in the range studied (0.5–2 M).

The cyanidation process is affected by a number of influential parameters, such as the availability of oxygen at the solid–liquid interface, the pH and Eh of the solid–solvent …
