  • Environment: Cyanide-free gold processing solution launched

    New technology that delivers commercial-scale, cyanide-free gold processing has been released by Clean Mining. The company works to transform gold production worldwide in an environmentally responsible manner. The innovative, cost-effective process replaces cyanide with a safer, less hazardous chemical reagent, thiosulphate.

  • How to set up an eco-friendly gold processing plant

    07.11.2019· Traditional gold processing methods generally use the toxic chemicals cyanide or mercury as reagents to extract gold particles from ore, exposing miners and the environment to toxic waste and gases. In contrast, Clean Mining offers an environmentally-sound gold processing technology that uses an inorganic compound, thiosulphate, in the place of toxic chemicals.

  • Cyanide Wastewater Treatment in Gold Cyanidation Plant

    The two-step precipitation method is a high-efficient closed-circuit full-circulation method developed for small and medium gold cyanidation plant with high concentration of SCN- wastewater, which realizes the “zero release” of wastewater.

  • Gold Extraction, Gold Cyanide, Gold Manufacturing Process

    Compared with gold CIP process and other traditional gold extraction processes, Xinhai gold CIL process greatly shortens the cyaniding time, reduces the capital backlog in the gold retention stage. 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

  • Cyanide Use in Gold Mining Earthworks

    A sodium cyanide solution is commonly used to leach gold from ore. There are two types of leaching: Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. The cyanide dissolves the gold from the ore into the solution as it trickles through the heap. The pad collects the now metal-impregnated solution which is stripped of gold and
