10-15TPH Placer Gold Washing Equipment Selection Guide for African Mine Conditions
Small to medium scale placer gold mines across West & East Africa commonly operate 10–15 tons per hour wash plants. Most African sites face typical challenges: high clay content in raw ore, limited stable grid power, variable water supply, remote location for spare parts transportation, and budget constraints. Improper equipment matching often leads to gold loss below 70% recovery rate, high downtime, and extra operation costs.
This guide focuses on 10–15TPH capacity placer gold washing flow, matched for real African mine geological conditions, with verified operational data from our running projects in Burkina Faso, Sierra Leone, Mali and Mozambique.
1. Core Challenges of African Placer Gold Deposits (10-15TPH Scale)
- High clay cemented ore: 30%~60% clay content is common. Simple screening cannot break clay lumps, fine gold trapped inside clay balls will be discarded with tailings.
- Unstable power: Most remote mines rely on diesel generators instead of national grid electricity.
- Water shortage risk: Dry season water volume drops sharply; water recycling system is mandatory for long-term running.
- Gold particle distribution: Coarse gold + fine free gold mixed, requires multi-stage recovery.
- Maintenance restriction: Limited local skilled technicians, equipment structure needs simple design, easy spare part replacement.
2. Recommended 10-15TPH Placer Gold Washing Equipment Package
Two optional configurations: Option A: High-clay ore version (most popular in Africa) & Option B: Low-clay sandy placer version
| Equipment Name | Spec | Installed Power | Function |
|---|---|---|---|
| Vibrating Gold Washing Machine (Clay scrubber) | 10-15TPH | 22kW | Wash & disperse clay balls, liberate encapsulated gold |
| Trommel Screen | Φ1.2m×4.5m | 7.5kW | Separate large stones >10mm |
| Gold Centrifugal Concentrator | 80 type | 5.5kW | Recover fine gold 0.04~0.2mm |
| Shaking Table | LY4.5 | 1.5kW | Concentrate upgrading for coarse gold |
| Slurry Pump | 3/2C-AH | 11kW | Transport ore slurry |
| Diesel Generator Set | 75kW | - | Power supply for off-grid African mines |
Field Verified Data (High Clay Ore): Total water consumption: 8~12 m³/h, gold recovery rate can reach 82%~88%. If skip clay scrubbing and use trommel only, recovery drops sharply to 55~68% due to clay wrapped fine gold loss.
3. Standard Processing Flow for 10-15TPH Placer Gold Plant
- Raw ore feeding → Vibrating gold washer scrubbing (break clay lumps)
- Trommel screening: discard large waste rock oversize
- Slurry enters centrifugal concentrator to capture fine free gold
- Centrifuge concentrate sent to shaking table for further upgrading
- Tailings slurry → Water recycling tank, 75~85% water reused to cut water cost
4. Key Selection Tips for African Mining Investors
✅ When to pick Vibrating Gold Washer
Clay >25% in raw ore, sticky soil. This is the most common scenario in West Africa deposits.
✅ When to use simple trommel only
Raw ore is loose sand, clay below 10%. Save investment cost, but not suitable rainy season sticky ore.
Power reminder: For off-grid mine, select 75kW diesel generator for full 10-15TPH line. Avoid overload shutdown, we have multiple projects running in Burkina Faso and Sierra Leone with this generator match.
Spare parts: Prepare wearing parts (rubber lining, screen mesh, impeller) before starting mining. Delivery cycle to inland African ports takes 30~55 days by sea.
