Straight gravity concentration of this ore, using the flowsheet shown, would result in a mixed goldtungsten concentrate containing much sulphide which is not desirable for marketing. Consequently, it is evident that other concentration processes must be incorporated in the flowsheet to produce separate marketable concentrates of tungsten and gold.
Separate the gold from unwanted rocks and minerals using one of several methods. You can mix the gold ore with sodium cyanide, which will attach itself to the gold and separate other elements such as zinc. Or pan the gold manually in water to separate gold from the gravel and sand in a stream.

Feb 24, 2013· was351, Depending on gold to silver ratio content of the metal, the silver in aqua regia can make it hard to dissolve the gold as the silver chloride forms a crust keeping the acids from dissolving the gold, and then also the gold can make it hard for nitric acid to get at the silver to remove the silver copper from the gold.
We want pure gold, but goldbearing rocks include lots of other materials such as quartz, calcite and the sulfides of other metals. We need to separate the gold from everything else in the rock so the rock needs to be treated in some way. In New Zealand we chiselled some rocks from an outcrop near a small creek.

An example implementation of the proposed method are the results of the following experiments. Flotation concentrate Berezovsky mine (Ural) size contained mm 38 g/t gold.
Gold is an almost nonreactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore.
