    Cyanide. In the late 1800s, cyanide started to be used to concentrate and capture gold from ore in a similar process to the mercury extraction, but is more efficient and loses less gold to the tailings. Once the rock is pulverized, it is mixed with water to create a slurry and a cyanide solution is added. This aqueous cyanide solution dissolves the gold and can then be extracted using a number

  • Refractory Gold SGS

    The other parameter that SGS experts consider when designing refractory gold treatments is whether or not to preconcentrate the gold-bearing ore. This is usually done by flotation of arsenopyrite, pyrite, or other gold-bearing sulfides. To be economically justifiable, preconcentration should meet two objectives. First, the gold recovery to the concentrate should be sufficiently high that the
