How to Test a Rock for Gold | Sciencing
· Take a rock that contains gold in it – this process works best on quartz rocks – and set it inside a glass jar. Add white cooking vinegar to the jar, covering the entire rock and then some with the vinegar. The acid-based vinegar slowly dissolves the quartz crystals surrounding the gold, leaving only bits of quartz attached to the gold.

· Gold/silver base metal concentrate deportment. Smelters typically pay >95% (Au) and 90% (Ag) in copper and lead concentrates, but will only pay 60-70% (maximum, depending on degree of Pb/Zn smelter integration) for gold and silver in zinc concentrates. Cost drivers are also important in flowsheet selection, and are summarised in Table 3.

hard rock mining processing plant ore gold flowchart. The hashing stage corresponding to metal extraction and recovery stages is a little more complex for gold ores, as the optimal process flowsheet selection choice is heavily dependent on a good understanding of two fundamental geometallurgical parameters, the gold mineralogical associations, and the gold particle size and liberation
Processing, smelting and refining gold | World Gold Council
The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it ...
