Cyanide-free gold recovery - CSIRO

    The Going for Gold process requires some additional 'off-the-shelf' components and a new configuration, but is not complex and can be customised to deal with different ore types. It could allow small gold producers to mine low-grade, uneconomic or stranded gold deposits, as well as gold reserves in jurisdictions where cyanide-use is banned or restricted.

    A method called the cyanide, or heap leach, process has gained acceptance within the mining industry because it is a low-cost way of processing lower-grade silver ores. However, the ores used in this method must have certain characteristics: the silver particles must be small; the silver must react with cyanide solutions; the silver ores must be relatively free of other mineral contaminants ...

    Processing, smelting and refining gold | World .

    With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators. For extracting gold from low-grade ores, heap leaching is practiced; huge heaps are sprayed with a dilute solution of sodium cyanide, and this percolates down through the piled ...
