Gravity Separation - an overview | ScienceDirect Topics

Gravity separation relies on forces. This chapter describes units, circuits, and strategies that are used to recover gravity-recoverable gold GRG from very high-grade gold particles and from sulfidic particles with low-grade gold content.

    Summary of Gold Gravity Separation - cnlitereagent.com

    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.
