  • Percolation leaching SAIMM

    The complexity of percolation leaching in practice is confirmed in a paper by J.F. Lupo of Newmont Mining Corporation. Although the paper deals with sustainability, the focus is on issues affecting metal and solution recovery, solution flow and containment, and stability of the ore heap. There are many other aspects mentioned, including variations

    Thus it is seen that by my method percolation leaching of slimes is accomplished. One of the factors that aids the rate of percolation is probably the cohesiveproperty of water which keeps the minute streamlets of water continuous. This appears to be the converse of the same principle which causes sap to run up the trunk of a tree. The net effect is

  • Heap leaching

    Heap leaching is an industrial mining process to extract precious metals, copper, uranium, and other compounds from ore via a series of chemical reactions that absorb specific minerals and then re separates them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then
