  Kinetics and reaction mechanism of gold cyanidation: …

  2005111 · The current status of the mechanism of gold cyanidation based on diffusion and surface adsorption–reaction models are reviewed. Published rate data based on chemical oxidation from flat gold surfaces in pure aerated cyanide solutions are analysed to show a reaction order of 2.7 with respect to cyanide at low concentrations.

  Improvements to the cyanidation process for precious metal …

  201811 · Cyanidation is the main technique for precious metals recovery in the mining industry. This hydrometallurgy technique consists in an electrochemical process that oxidizes gold and reduces oxygen with cyanide solutions at pH values above 10.5. During cyanidation, many factors are critical for precious metals dissolution from Waste Printed ...

  Designing the SART process – A review - ScienceDirect

  201831 · These results are supported by operational data from gold cyanidation plants which have copper minerals in the ore, such as Gedabek plant (800 mg/L), Yanacocha gold mill plant (1000 mg/L), Telfer (1000 mg/L), and Mastra plant (1500 mg/L) (Estay et al., 2012c; Adams, 2013). The SART process is included in these plants, reducing the copper ...
