Ordinary flotation process seems not available for raw ore. At this time, "poor, fine, miscellaneous" copper ore dressing process – the biological leaching process was born. The following is a brief introduction of biological leaching of a copper production line. Common microbe mineral processing technologies are heap leaching and leaching.
Gold CIL production line Process Introduction. CIL (Carbon in Leach) process is the most efficient method to leaching and recovering gold from gold ore, The most protruding features is that leaching and adsorption are carried out at the same time, which greatly saves the cost of .
Leaching by Cyanidation. Although it was known in 1840 that cyanide solutions dissolved metallic gold, the process for ores was not developed until 1887 by the MacArthur Forrest Syndicate. Since that time it has been widely used for the recovery of gold and silver from certain types of ores.
In heapleaching, the ore is placed on openair pads and the cyanide sprayed over it, taking several weeks to leach down to an impervious base. The solution then pours off the pad into a pond and is pumped from there to a recovery plant where the gold is recovered.
required for gold leaching by cyanidation. Another example of chemical interference is the presence of graphitic carbon in a gold ore. This species, which occurs naturally in many orebodies, particularly in the SW United States and West Africa, is able to readsorb gold cyanide from the leach solution, lowering overall gold recovery. Finally ...
