Gold Recovery Plant For Sale: Centrifugal Concentrator for
When you want to efficiently recover fine gold from gold bearing ore, you need a Centrifugal Concentrator (CC). For example, a 1-3 TPH (tonnes per hour) unit will handle both alluvial and hard rock material. One method with alluvials is to use a scrubber/trommel that washes and sorts the feed before it enters the Centrifugal Concentrator. If needed, tailings can be run into a sluice boxОнлайн-запрос

How to Use Bleach on Gold Ore to Remove Gold | Sciencing
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 method used for goldОнлайн-запрос
