Gold ore processing typically involves six steps. A gold ore processing plant uses one or more steps in combination to process gold ore. Crushing: Sometimes gold is encased in rock particles, and crushing can release the gold. Crushing can also control the particle size of ore and increase the degree of mineralization to meet the needs of different mineral processing.

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, …
