LITERATURE REVIEW AND THERMODYNAMIC MODELING OF GOLD CYANIDATION PROCESS

The gold leaching process often operates far from optimal range, evidenced by requiring excessive reagent consumption (ie cyanide and oxygen) and dependent on feed mineralogy. There have been some efforts to develop models for estimating cyanide consumption under real leaching conditions. For example, Adams (1990) studied the effects of ...

Estimated Water Requirements for Gold Heap-Leach

The Heap-Leach Process Briefly stated, gold heap leaching is a hydrometallurgical process designed to treat amenable low-grade gold ores that contain roughly 0.5 gram per metric ton (g/t) gold to 1.5 g/t gold (Marsden and House, 2006; Wong Wai Leong and Mujumdar, 2010). The ore is stacked by various types of equipment

Gold Project Flowsheet Design SRK Consulting

Another factor that contributes to the complexity of processing gold ores is the presence of adsorption-active substances that trap dissolved gold and carry it with the tailings, i.e. ‘preg-robbing’. This is one of the most challenging type of ore. To avoid these traps, the flowsheet designers use methods for separating adsorption-active ...

Gold Fields South Deep Gold Mine - How we process

From the time that the ore hoisted from underground and enters the processing plant, it takes up to five days before the process of smelting into gold bars can commence. South Deep’s gold plant has the capacity to process around 330,000 tonnes of ore per month and the capability to treat more underground ore than most other plants in the Far ...
