    Here I present an Process EXAMPLE of Gold Extraction Cyanide in which the cyanidation feed consists of a pyrite concentrate floated after the selective flotation of a copper-gold concentrate. The pyrite concentrate is reground to 90% minus 325 mesh and aerated in a high-lime solution prior to cyanidation. It contains 99% sulphides of which 10 to 20 percent is pyrrhotite and 0.3 to 0.7% ...

  • The Borax Method of Gold Extraction for Small-Scale Miners

    this is not the case: cyanide does not extract significant amounts of gold locked in mercury flour. In order to demonstrate this to miners in Tanzania, samples of tailings were collected in 2009 before and after cyanidation. The results in Table 1 clearly show that only a fraction of gold was captured by cyanidation, and high-grade tailings were discarded. 2. Analytical work for this ...

  • Dissolve Gold and Silver with Cyanide

    Since cyanide reacts with the gold and silver, it is consumed during leaching. The cyanide can and will also react with other undesirable metals and is essentially wasted. Therefore, if excess cyanide is not added to the leach circuit, the amount of available or free cyanide’ decreases, limiting gold and silver dissolution. For this reason, free cyanide is added continuously at the ball mill ...
