Gold Leaching Piping Size

  • Leach Field Requirements

    Effective Leaching Area - The size of the leachfield is determined by the total of the areas of the trench bottom and sidewalls beneath the leach pipe. Example: A trench that is four feet deep, 1 ½ feet wide and 50 feet long with the leach pipe on top of 2 ½ feet of drain rock, has an effective leaching area of 325 sq. ft.

    different leaching kinetics. When gold is directly exposed to the surrounding phase it has a fast leaching kinetic. On the other hand, gold attacked through ore porosity, like in heap leaching, exhibits slow dissolution kinetics. Figure 1 shows four different classes of gold, each one having a different leaching behaviour. One can see that gold ...
