Jul 11, 2018 The methodology selected is a function of the mineralogy of the ore. If the gold is associated with oxides, for example, it can be amenable to heap leaching. The grade also plays a key role. Heap leaching is used for low-grade oxides, while high-grade ore with or without oxides is better suited to CIP or CIL methods, says Bundo.+
The kinetic leach data were well fitted by the CIPCIL leach model developed by Nicol et al, giving estimates of the leach rate parameter of 72.1 hr and leach tails grade after infinite leach time of 0.17 gt, confirming fast leaching of the 72142 B sample. The tests ended with gold adsorption from thiocyanate solution onto carbon.+
