  • Major Mines & Projects | Martabe Mine

    A conventional Carbon-In-Leach (CIL) plant is the process plant at the Martabe Gold Mine with a capacity that exceeds 6 million tonnes of ore per annum. The process plant is operated continually with the exception of maintenance shutdowns. It is relatively simple to extract gold and silver from the Ore, the key steps are: • Ore crushing.

  • Gold processing 101

    At current gold prices this is worth about US$600. Both smelter treatment charges and oxidation or bio-leach costs are at least $200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around 0.5. Clearly this is a function of gold price, but in the current gold price and cost

  • Estimating process design gold extraction, leach residence time and

    Plant design parameters for gold extraction, leach residence time and cyanide consumption are generally determined from standard bench-scale bottle roll or agitation leach tests. The application of laboratory data to process design has essentially evolved from the testing of oxide or low cyanide-consuming ores. Such scale-up factors may not be appropriate for ores that deplete cyanide and

  • Elution and Carbon Reactivation

    During the CIL process, gold is leached from the ore using an alkaline cyanide solution. The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed.
