Applicability: ????? ??????? ???? ??????? ?????? ?? ??? ????? ??. ???? ??????? ????, ????? ?????? ?????????, ????? ???? ???? (????, ?????? ??????????, ????????).

Principle: Leverages gold's high density (~19.3 g/cm³) vs. gangue. Separation occurs via fluid dynamics/centrifugal force in gravity concentrators.

????? ???????:

  • 1. ????? ??????? ????? (???? ???? ?????)
  • 2. ????? ?????? (????? ?????? / ?'?? / ????? ???)
  • 3.Concentrate Upgrading & Thickening → High-grade gold concentrate.
  • 4. ?????: ?????? ?? ????? ??????/?????????.

Pros: ???? ?????, ????, ??? ????????, ????? ????: 85%-90%.

Cons: ????? ????? ?? ??? ????; ?????? ?????? ???? ??? ???? ?????? ?? ??? ????.
