    Taking the gold cyanidation plant with processing capacity of 100000 tons and gold grade of 7.5 g/t as an example, gold CIL process can save the investment cost of $486000 than the CIP process, reduce the capital backlog of $201700, save and recycle capital of $675100 in advance excluding the cost of activated carbon.

  • 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.
