A 100 tonnes per hour (tph) placer gold mining plant would be used for the mining and recovery of gold from placers, which typically involve alluvial deposits. These operations are set up to process large amounts of soil and sediment to extract valuable minerals.
Components of a 100tph Placer Gold Mining Plant:
-
Feeding System:
- Grizzly Feeder: Pre-screens and removes oversize materials, and enables a consistent feed rate to the plant.
-
Scrubbing:
- Trommel or Scrubber: This rotating drum is used to wash gravel, break down clay, and remove materials that might bind gold particles.
-
Screening:
- Vibrating Screens: These separate coarse from fine materials after they have been washed in the trommel.
-
Concentration:
- Jig Concentrator: Used to separate heavy gold particles from lighter material through pulsation of water.
- Shaking Tables: Further concentrates material, making use of gravity and motion to sort precious metals.
- Hydrocyclones: Used to classify and recover fine gold particles.
-
Recovery:
- Sluice Boxes: Utilize riffles and mats to capture fine gold through water flow.
-
Water Supply System:
- Water Pump: Essential for providing the required water supply for washing and sluicing.
- Recycling System: Helps minimize water usage by recirculating water within the plant.
-
Tailings Disposal:
- Tailings Management Unit: Proper management to dispose of or store tailings from the separation process to minimize environmental impact.
-
Power Supply:
- Generator: If the site is remote, ensuring a continuous power supply to the plant.
Additional Considerations:
- Mobility: Portable plants are often preferred for placer mining to allow movement to new sites as needed.
- Environmental Impact: Implementing measures for reducing environmental footprint, such as using eco-friendly chemicals and erosion control.
- Regulatory Compliance: Ensuring operations meet local mining and environmental regulations.
Applications and Benefits:
- Efficiency: Capable of processing large volumes with high recovery rates for fine gold.
- Versatility: Suitable for different alluvial conditions and adaptable to varying terrains.
Consulting with engineers and manufacturers specializing in placer gold mining plants will provide you with a tailored solution that fits your site-specific requirements and enables optimal efficiency and gold recovery.
