designing of a vat leaching plant for gold processing

  • Cyanide Use in Gold MiningEarthworks

    Vat (or tank) leaching The ore is mixed with cyanide solution in large tanks. Although the chances of spills are lower because the leaching process is more controlled the resulting waste known as tailings is stored behind large dams (tailings impoundments) which can and do fail catastrophically .

    Apr 25 2018 · Heap leaching can take anything from a couple of months to several years. In the case of gold recovery heap leaching generally requires 60 to 90 days to leach the ore compared to the 24 hours required by a conventional agitated leach process. Gold recovery is also usually only 70 compared with 90 recovery in an agitated leach plant.

    However more complex or novel processes will require progressive stages of testwork from laboratory to continuous pilot plants to prove up and optimise the process ahead of plant design. Grind size is usually the key process parameter in a leach plant as grinding represents the highest energy input and cost element in the overall process.
