This rock gold process uses crushing, closed-circuit grinding, gravity roughing and shaking table concentration to separate high-purity gold concentrate from hard rock ore.
The Small and middle scale gold gravity separation processing plant
1. Crushing Stage
Raw ore is fed into a vibrating feeder and then crushed by a jaw crusher (and optionally a secondary crusher) to reduce the size to below 10–20 mm, ensuring suitability for downstream processing.
2. Screening Stage
Crushed material is screened by a vibrating screen to separate qualified particles from oversized material. Oversized particles are returned to the crusher, while qualified material proceeds to the next stage.
3. Grinding (Optional)
For hard rock ores where gold is locked within the matrix, a ball mill or wet pan mill is used to achieve proper liberation. This stage is typically not required for alluvial or oxidized ores.
4. Classification
Material is classified by particle size using spiral classifiers or hydrocyclones:
Coarse particles are directed to jigs. Fine particles are directed to centrifugal concentrators or shaking tables.
5. Gravity Concentration
Jig Machine: Recovers coarse gold with high capacity and low operating cost
Centrifugal Concentrator: Efficiently recovers fine gold with high recovery rates
Shaking Table: Final cleaning stage to improve gold grade and remove impurities
6. Tailing Treatment
Tailing can be further processed through secondary recovery systems or, if necessary, treated by CIL/CIP processes to recover ultra-fine gold.
Achieving 95%+ gold recovery rates.
Dis-assemble and assemble is convenient, only takes half an hour. can move from one site to another site easily.
It is suitable for small, medium- large sized gold washing, screening and separation plants. Low operating cost, easy maintenance, low noise; Quick disassembly to adapt to different mine sites.
The gold washing machine is made of durable materials to withstand long hours of continuous operations. The trommel scrubber has a good washing and processing effect for gold ore with much sticky/clay.
The gold trommel wash plant adopts a circulating water system, which meets environmental protection mining requirements.
The portable gold washing station integrates mining and gold beneficiation operations, including mining systems, beneficiation equipment, water supply systems, tailings treatment systems, power supplies, etc.
