how to produce gold in vat leaching

  • Agitation Leaching Theory And Practice Biology Essay

    Ore Preparation. The first step in ore preparation is crushing and grinding, which reduces the particle size of the ore and liberates the gold for recovery. Ore that contains free gold may not yield a sufficiently high recovery by sole use of cyanide leaching, due to a very long dissolution time for large gold particles.
