Heap leaching. Computer simulation as an alternative

2015-7-1  As the feed mode cyanide is 1 g/h, the time scale of hours may be adopted for the scale cyanide consumption in grams. As can be seen, there are two characteristic regions. The plot is becoming fronts (transient) corresponding to the peak on the kinetic curve, and the fronts movement phase (quasi-stationary) corresponding to the shoulder, with very different specific consumption of

Modelling and simulation of gold ore leaching

2009-11-20  A leaching model for gold ore that takes into account the impact of cyanide and oxygen concentrations as well as gold surface exposure on leaching performance is developed. Cyanide consumption is estimated by an empirical model that is a function of ore particles size distribution as well as cyanide, copper and sulphur concentrations.
