Gold Cyanidation Technology

The process, called gold cyanidation, makes gold water-soluble, and thus easier to isolate from the ore. While using cyanide allows for the profitable extraction of gold from low quality ores, it ...

    Cyanide-free gold recovery - CSIRO

    The infrastructure for a processing plant that uses cyanidation typically costs 30 million, and is therefore, a barrier to entry for gold miners with smaller deposits that do not fit into the large-scale economies of gold production. Gold recovery by cyanidation is also of environmental and safety concern as it relies on the use of toxic cyanide.

    Cyanide Leaching | Mining | SGS

    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.
