  • What is the Alluvial Gold Mining Method?

    Alluvial gold mining method and equipment in the gravity separation process: 1. Pre-separation: Compared with other ore processing, the pre-separation before the alluvial gold mining is not 2. Separation gravity separation: The principle of gravity separation used for the alluvial gold Summary of Gold Gravity Separation,Gold gravity separation is the oldest gold extraction process. Gold generally occurs in a form of monomeric native gold in alluvial gold mines, and the particle size is generally greater than 16g/t. Therefore, gold gravity separation is one of the most effective and economical processing methods for alluvial gold extraction.
