Feb 09, · This end result of the panning process is the g concentrates which must be sifted through manually to extract the bits of g. G concentrates tend to be mostly iron, so they are also known as black sands. G concentrates are also made by grinding down ore, quartz, or other productive rock types into sand. This procedure is much faster and easier than panning, but the tradeoff is a final product that has less g

Many gbearing ores and concentrates are not readily amenable to cyanidation, owing to the presence of substances that consume the cyanide reagent before it can dissolve the g, preferentially adsorb the g as it dissolves (a phenomenon called pregrobbing), or completely surround the g particles in such a way as to prevent access by the cyanide leach solution. Such ores are referred to
