30 TPH Rock Gold Processing in Congo

JXSC telah merancang Diagram Alir yang lengkap dan menyediakan satu set lengkap mesin pabrik pengolahan & semua aksesori untuk rock gold processing in Congo. We offer a detailed layout design with base construction drawings accordingly.

1. The processing capacity required is 30TPH.
2. The raw material is rock gold.
3. According to the rock ore information obtained from the customer, the rock needs to be ground to a final size of 0-1mm to release gold from the rock.

• Pengumpan getaran
• Primary jaw crusher & fine jaw crusher
• Layar bergetar
• Pabrik bola
• Konsentrator sentrifugal emas
• Meja goyang
• Kotak pintu air
• Slurry pump & water pump
• Konveyor sabuk
• Tungku peleburan emas

Step 1. Feeding System

• Front-end loaders/dump trucks feed raw ore into the hopper.
• Pengumpan bergetar ensures steady and controlled material flow to the primary crusher.
• Pengumpan elektromagnetik precisely regulates feed rates for downstream crushing and grinding.

Step 2. Crushing Stage (Two-Stage Crushing)

• Primer Penghancur Rahang: Breaks down large rocks (<340mm) to intermediate sizes (<100mm).
• Fine Jaw Crusher: Further reduces material to 0-30mm via belt conveyor.
• Key Advantage: High reduction ratio (1:10), ideal for hard quartz gold ore.

Step 3. Screening Process (Closed-Loop Control)

• Layar bergetar classifies 0-30mm material:
  ✓ Acceptable size (0-20mm): Sent to grinding via transfer bin.
  ✓ Oversize (+20mm): Recycled to a fine jaw crusher.
• Quality Control: Ensures optimal grinding feed size (≤20mm).

Step 4. Grinding Circuit (Gold Liberation)

• Ball Mill: Wet grinds 0-20mm ore to 0-1mm slurry (-200 mesh, >85% passing).
• Critical Outcome: Achieves 90%+ gold liberation from host rock.

Step 5. Gravity Separation (3-Stage Recovery)

• Primary Concentration: Centrifugal concentrator upgrades slurry to high-grade concentrate.
• Secondary Upgrading: Meja goyang further purifies the centrifugal concentrate for direct smelting.
• Tailings Recovery: Sluice box scavenges residual gold from centrifugal tails.
• Recovery Rate: 80–90% overall (ore-dependent).

Final Product

Gold concentrate is smelted into gold bars.

30tph rock gold gravity separation System Advantages

1. Optimized Flow – Modular 5-stage design adapts to varied gold-bearing ores (e.g., auriferous pyrite-quartz).
2. High Recovery – Three-stage gravity separation + precise grinding (tailings grade <0.5g/t).
3. Cost Efficiency:

• Power consumption: ≤25kWh per ton.
• Wear parts lifespan: Jaw plates (6–8 months), grinding media (12 months).

4. Automation – Flow monitoring at key nodes.
