Definitions
- the metal bearing ore may be obtained from an open pit mine or the like and is crushed to produce an aggregate that is coarse enough to expose the desired mineral values but fine enough to allow intimate contact of the lixiviant system or solution therewith.
- the lixiviant solution may be distributed over the top of the metal ore heap via sprinklers, wobblers, or other similar equipment.
- the barren lixiviant “percolates” through the heap to perform its desired function with the metal and the resulting pregnant solution is then collected by an impervious leach pad or the like located at the bottom of the heap.
- the pregnant solution is then subjected to conventional mineral recovery techniques to obtain the desired precious metal.
- the ethoxylated aliphatic alcohols are commercially available from a plurality of suppliers. Based upon presently available data, the following four commercially available products appear to be especially effective. McCutcheon Description description Analysis results Ethoxylated Isodecyl alcohol A heavily branched ethoxylated aliphatic ethoxylate aliphatic alcohol. The average carbon alcohol chain length is 7.3 C's/molecule. The average ethoxylation is 4.5 moles/ molecule Ethoxylated 2-decylethoxy a heavily branched ethoxylated aliphatic aliphatic poly(ethyleneoxy) alcohol. The average carbon chain alcohol ethanol length is 6.7 C's/molecule.
- Capillary rise screening tests were performed using an 18 ⁇ 30 mesh sieved ore from a mine in Northern Nevada (Marigold Mine). The ore was prepared by first sieving to this size fraction. The 18 ⁇ 30 fraction was washed extensively with tap water to remove embedded clays. Material was dried overnight at 105° C. and then stored in an environmental chamber at 50% humidity and 25 C.
- Surfactants were run at 5, 20 and 100 ppm. Below the surfactants are described as one of three classes, those that no effect or does response (>95% of blank, approximate noise level of experiment), those that slightly decreased capillary rise with increasing dose (75% to 95%), and those that had a significant impact ( ⁇ 75% of blank).
- FIG. 2 Reference numerals used in FIG. 2 are as follows: 2 C-3 4 X-2 2-decylethoxy Poly (ethyleneoxy) ethanol 6 C-5 8 C-1 10 X-1 12 C-6 14 C-2 16 X-4 ethoxylated alcohol 18 C-7 sodium dodecyl diphenyl oxide disulfonate
