2005-10-1  A gold ore from Northwestern Quebec (Canada) was characterized and used to perform kinetic cyanidation experiments at the plant operational conditions. Two rate equations that take account of the ore size distribution have been developed for this ore. The kinetic equation describes the gold dissolution and the second the free cyanide consumption.

2012-6-2  This paper investigated the kinetics of leaching gold from refractory gold ores by ultrasonic-assisted electro-chlorination. The effects of ultrasound time ratio, initial hydrochloric acid concentration and leaching temperature on the kinetic parameters were discussed. It is found that the leaching ratio goes up with all the factors increasing.

2008-8-1  Carbon-in-leach testing, however, showed normal rapid kinetic behavior, with the same ultimate gold extractions being reached in much shorter elapsed times. Kinetic-curves based on washed solids assays also exhibited more typical leaching characteristics. The results bore all the hallmarks of some equilibrium inhibition of the leaching.

De Andrade et al proposed two lumped kinetic models for gold ore cyanidation, which are the kinetic equation of gold dissolution and the cyanide consumption, respectively. Based on kinetic...

2013-7-18  Furthermore, two previously established fundamental kinetic equations, both based on the electrochemistry of pure gold cyanidation, were adopted for gold ores and incorporated into the variable order kinetic equation. The first equation was derived from the theory of mixed potentials, while the second was based on Habashi's cyanidation model.

2020-8-28  Kinetic models were developed for the leaching of gold from the ore, adsorption onto activated carbon and preg-robbing at the ore surface. A variable order empirical model of the Mintek form was used to describe leaching, while adsorption was modelled using the film-transfer model. ...

2009-11-20  Exposed gold at the ore surface The kinetic behaviour of gold exposed on the ore surface is similar to the one of completely liberated gold grains. The major difference between the two classes of gold, is that the accessible surface of partially liberated gold is much smaller.

2021-4-1  The study of the kinetic behaviour or models is important to design and scale up the leaching process, since they describe the rate of dissolution of copper, cobalt and iron in copper oxide ore by H 2 SO 4 solutions as lixiviant. Different reaction kinetic models were investigated for their suitability to describe the rate of leaching process, the currently known ones are: zero-order, half-order, first-order,

2020-9-7  The dissolution process kinetics and optimization of iron from Akwuke ore were investigated in this study. The effects of process parameters such as agitation rate and ore particle size on the dissolution process were also examined. The Akwuke ore was characterized employing the XRD, FT-IR, SEM, and UV-spectroscopy.

2017-9-27  the Au-Cu sulfide ore, gold dissolution occurred concurrently with copper dissolution at 25 °C. This observation was attributed to galvanic interactions since the sulfide ore naturally contained pyrite. Increases in glycine concentration also improved the dissolution of both copper and gold from the sulfide ore.

2019-4-3  type ore classification system called ‘Mat-Type’ was used to classify the various ore types based on a number of control parameters that would manage ore quality and ensure efficient and economic recovery of copper and gold. Ore containing mineral assemblages considered to be of ‘poor quality’ were directed to long-term stockpiles ...
