JXSC Congo Gold Processing Plant: Alluvial Gold Mining Equipment 100TPH Capacity
By JXSC Mine Machinery Factory – Your Trusted Partner in Africa
Why 100TPH? A Sweet Spot for Congo Alluvial Gold
If you're running an alluvial gold operation in Congo—whether in the dense forests of Orientale Province or along the rivers of South Kivu—you know the challenge: you need a plant that can handle volume, but you don't want to overinvest in a massive system that's hard to transport or operate.
100 tons per hour (TPH) is the goldilocks zone. It's big enough to move serious material, but small enough to set up with a handful of trucks and a medium-sized generator.
At JXSC Mine Machinery Factory, we've shipped dozens of 100TPH alluvial gold processing plants to Congo. They're proven performers. Let's walk through what makes this setup work—and why JXSC is the name you can trust in Central Africa.
What's in a JXSC 100TPH Alluvial Gold Plant?
A complete 100TPH alluvial gold plant from JXSC typically includes:
| Equipment | Purpose |
|---|---|
| Trommel Screen | Wash and classify raw feed |
| Vibrating Sluice Box | Primary gold recovery |
| Centrifugal Concentrator | Fine gold capture |
| Shaking Table | Final clean-up & concentrate upgrade |
| Slurry Pump, Water Pump | Material transfer & water supply |
| Control Panel & Diesel Generator (optional) | Power supply |
These are modular, skid-mounted units. You can ship them in 20ft or 40ft containers, and assemble on-site in 3-5 days.
How It Works: Simple 4-Step Process
Step 1: Feeding & Washing
Raw alluvial material (gravel, sand, clay) is fed into the trommel screen via an excavator or loader. High-pressure water jets break down clay lumps. The trommel rotates, separating oversize rocks (+10mm or custom size) from undersize gold-bearing material.
Why this matters: In Congo, many deposits have sticky clay. Our trommel is designed with internal riffles and heavy-duty spray nozzles to handle it.
Step 2: Primary Recovery – Vibrating Sluice
The undersize slurry flows into our vibrating sluice box. It's like a traditional sluice, but with vibration. This lifts trapped gravel and redistributes the material, so gold doesn't get stuck in riffles.
Recovery rate: 85-90% for coarse gold.
Step 3: Fine Gold Recovery – Centrifugal Concentrator
The tailings from the sluice pass through a centrifugal concentrator. This spins at high RPM, creating a G-force that traps even fine gold (down to 30-50 microns). The concentrate is discharged manually or automatically.
Recovery rate: 95%+ for fine gold.
Step 4: Final Clean-Up – Shaking Table
The heavy concentrate from the centrifugal goes onto a shaking table. With water flow and vibration, the table separates gold from black sand, magnetite, and other heavy minerals. You get a clean gold concentrate ready for smelting.
Congo Case Studies: Real Projects, Real Results
Case 1: Orientale Province – 100 TPH Plant, 2022
Customer: Local mining cooperativeChallenge: High clay content, riverbank deposit
Solution: JXSC 100TPH plant with high-pressure water cannon & heavy-duty trommel
Result: 2.5g/m³ recovery, 3-man daily operation, 95% production uptime
Case 2: South Kivu – Mobile Plant, 2023
Customer: Small-scale investorChallenge: Remote site, limited infrastructure
Result: First gold pour in 4 days, annual recovery of 15+ kg
Case 3: Katanga (copper area) – By-product Gold Recovery
Customer: Copper-cobalt mine looking to capture goldChallenge: Very fine gold in weathered ore
Solution: JXSC centrifugal concentrator + shaking table integrated into existing circuit
Result: 0.8 g/t gold recovered, paying for the equipment in 6 months
Design Features: Built for Africa
1. Heavy-Duty Construction
We use Q345B steel for structural parts, double-walled trommel, and reinforced sluice box. These survive the roughest Congolese roads.
2. Easy Maintenance
All bearing points are greasable. Trommel screen panels are bolted, not welded, so you can ｒｅｐｌａｃｅ them in the field. Slurry pumps are designed with easy-access impellers.
3. Water Efficiency
Our plant is designed to recirculate water. You need about 80-100m³ of fresh water per hour, but with a settling pond, you can reuse 70%.
4. Modular Transport
Each major component is under 2.5m wide and fits inside a 20ft container. That means you can ship to Pointe-Noire (Congo-Brazzaville) or Matadi (DRC) and truck to site.
What Ores Does This Work For?
| Ore Type | Suitability | Notes |
|---|---|---|
| Alluvial gold sand | Excellent | Standard setup |
| River gravel | Excellent | Upgrade trommel for boulders |
| Weathered laterite clay | Good | Need high-pressure water |
| Rock ore (hard) | Not suitable | Use a crushing circuit instead |
| Offshore/beach sands | Good | Mildly corrosive, use SS piping |

Operation & Maintenance Tips
Daily Checklist:
Water level check – Never run pumps dry.Screen inspection – Check for wear or tears, especially after heavy rain.
Vibration monitoring – Listen for unusual knocking at sluice or table.
Concentrate cleanup – Pull concentrate at end of shift; don't let it build up.
Weekly Maintenance:
Lubricate all bearingsCheck belt tension on trommel
Clean centrifugal concentrator bowl
Flush shaking table grooves
Common Problems & Fixes:
Clay clogging trommel? Increase spray pressure or add a scrubber drum ahead.Gold floating away? Reduce water flow in sluice; check riffle height.
Concentrator vibration? Unbalanced bowl; clean and re-level.
JXSC vs. Other Manufacturers: Honest Comparison
| Factor | JXSC | Competitor A (low-cost) | Competitor B (Western brand) |
