Model for heap leaching of gold ores by cyanidation ...
1997-1-1 The objective of this study is to develop a model which describes the heap leaching process for gold extraction from non-refractory ores. The model considers the cyanidation reaction in a bed of uniformly sized spherical porous mineral particles, through which the leaching solution trickles. The leaching agents diffuse into the porous particles ...
