Sure, I can provide an overview of what a 100 tons per hour (tph) alluvial gold and diamond processing plant might include.
100TPH Alluvial Gold & Diamond Processing Plant Overview
1. Introduction to Alluvial Processing
Alluvial processing involves extracting gold and diamonds from riverbeds, floodplains, and other sedimentary deposits. The materials are usually unconsolidated and can be processed with minimal comminution.
2. Feed Preparation
- Grizzly Feeder: It removes the oversize material and allows fine particles to pass through.
- Trommel or Rotary Scrubber: This is used to wash the clays and silts from the gravels and break up any cemented layers of material.
3. Screening Process
- Vibratory Screens or Trommel Screens: These separate the finer material from the larger gravels. Different screen sizes ensure proper classification of materials for downstream processing.
4. Gravity Separation Equipment
- Jig Concentrators: Used to separate dense particles like gold and diamonds from lighter aggregate material.
- Shaking Tables: Further refine the separation by utilizing a combination of gravity, water flow, and mechanical shaking.
5. Concentration and Recovery
- Sluice Boxes: Commonly used for gold recovery due to their efficiency and simplicity.
- Centrifugal Concentrators: Such as the Knelson or Falcon concentrators, are highly effective at recovering fine gold particles.
- Diamond Recovery Units: These often incorporate grease tables, x-ray sorters, or other specialized equipment to recover diamonds based on their unique properties.
6. Tailing Management
- Thickening Tanks: Used for tailings management by increasing the solids content of tailings streams before disposal.
- Tailing Storage Facilities (TSFs): Ensure environmentally safe storage of tailings material.
7. Water Supply and Management
- Water Pumps and Tanks: Essential for maintaining the required water flow and pressure in the processing plant.
- Water Recycling Systems: These are vital for minimizing water consumption and environmental impact by reusing process water.
8. Quality Control and Environment
- Assay Laboratory: Regular sampling and analysis ensure product quality meets exacting standards.
- Environmental Monitoring: Adherence to local environmental regulations and ensuring strict environmental safeguards are in place.
9. Support Infrastructure
- Power Supply: Generators or connection to a power grid.
- Workshops: For maintenance and repair work.
- Accommodation & Mess Facilities: For staff, if the plant is in a remote location.
10. Automation and Safety
- Control Systems: Automated controls and monitoring systems enhance operational efficiency and safety.
- Safety Gear and Protocols: Ensure the well-being of workers through rigorous safety protocols and equipment.
This setup provides a comprehensive overview of a typical 100tph alluvial gold & diamond processing plant. The specific design and equipment will depend on the ore characteristics and the project requirements.
