  • Precious Metal Heap Leach Design and PracticeOre-Max

    A recent review (Kappes 1998) concluded that for a "typical" Nevada-type ore body with ore grade of 3.0 grams gold/tonne (0.088 oz/ton) the mill recovery would have to be 21 higher than the heap leach recovery to achieve the same return on investmentand this is very seldom the case.

    African gold plant. These figures are not a standard but reflect the nature of the ore and the design basis for a particular situation. The ore is first reduced in size (typically 80 passing 75µm) to ensure that all non-refractory gold is readily accessible for cyanide leaching. There are several variations of comminution circuits used in the

  • A Poor Man s Method of Smelting Gold Sciencing

    You can remove the most common metals found in gold ore (copper zinc and lead) using elements that bond with oxygen at lower temperatures than gold. This oxidation process will make copper oxide zinc oxide and lead oxide — all of which are less dense than pure gold and will float to the top of your crucible allowing the slag to be sloughed off.

  • Stamp millWikipedia

    A stamp mill consists of a set of heavy steel (iron-shod wood in some cases) stamps loosely held vertically in a frame in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft.As the cam moves from under the stamp the stamp falls onto the ore below crushing the rock and the lifting process is repeated at the next pass of the cam.
