WhatsAppGet PriceGet A QuoteOre processing is by conventional cyanide heap leaching, which produces a pregnant leach solution (PLS) containing 1–2 ppm of gold, together with 1000 ppm or more of copper. The PLS is treated by column ion exchange, using Dow’s gold-selective MINIX resin. Loaded resin is stripped with an acidic thiourea solution, from which gold and silver are electrowon on to stainless steel mesh

So If you find blue clay contains a lot of black sand, this may be a very good sign that gold is also nearby. Alluvial gold is most found in blue clay and is in clay-laden gravel or between thin layers of rock.
