Heap leaching, the future InfoMine
In today's world of complex ores and milling processes, heap leaching is often forgotten. However, the future of largescale mining depends heavily on heap leaching. New ore deposits are lower grade, more refractory, more difficult to drill, and face the challenge of rising costs, increased regulatory...

What is Bioleaching? InnovateUs
Bioleaching is much better and cleaner than the heap leaching using Cyanide; Significant advantage of bioleaching method is found in the pretreatment of refractory gold in ores and concentrates with high arsenic content. This is because, the bacteria tends to attract the arsenic minerals and oxidizes it;...
Heap Bioleaching of Refractory Arsenic Gold .
The purpose of this research was to evaluate the feasibility of heap bioleaching on refractory gold concentrate. The samples with an agglomerate agent were bioleached within a temperature range of 1528 °C for periods of 60 d, 132 d and 306 d, respectively, in leaching column. Then the residues were cyanide leached....

Cyanide Leaching | Mining | SGS South Africa
Cyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns....
