A rock gold gravity processing and recovery plant is designed to extract and recover gold from gold-bearing ores using gravity separation methods.
The principle of rock gold mining process is to maximize the recovery rate of gold & the associated heavy minerals from river firstly, and then separate gold from the associated heavy minerals by joint mining solutions such as gravity separation, amalgamation, etc.
The gold beneficiation process is gravity separation, flotation, magnetic separation, cip, cil, heap leaching and other combined methods. Alluvial/Placer gold process: The gold concentrate of placer gold ore has a high content and mostly exists in the form of sand grains. Therefore, gravity separation is often used when sorting. After pretreatment, desliming and washing of ore, …
The gold is extracted from gold mines, and it is not easy to get pure gold from gold mines. It needs a series of beneficiation equipment to process the rock gold to high-value gold. From ore to gold, the value has doubled several times, so …
