However, not all ores are successfully treated by gravity methods. You must test the ore to see if gravity methods will work on this ore. Often there are operators who set up ore processing plants in the gold bearing regions of Africa to process the local ores mined there. They process the ores produced by the miners for a fee.

2. Extraction Method of Silver in Gold-Silver Ore #1 Gravity Separation Method. Silver can be enriched by gravity separation, but its enrichment degree is much lower than that of gold. It is usually processed by a jig to collect coarse (greater than 0.1~0.2 mm) heavy minerals, namely natural silver, argyrite and hornsilite.

Gold is an almost non-reactive 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. This was the first commercial …
