JXSC Zambia Alluvial Gold Processing Plant 100TPH Flow Design & Equipment Cost
Why 100TPH for Zambia Alluvial Gold?
Have you ever wondered what it takes to process 100 tons of alluvial gold ore per hour? If you're working in Zambia's copperbelt or exploring the rich gold deposits along the Kafue River, you’ve probably considered a medium-to-large scale operation.
The 100TPH capacity is a sweet spot. It's big enough to generate real profits but not too massive to blow your budget. Many Zambian small-scale miners are upgrading from 20-50TPH plants to 100TPH after realizing the cost-per-ton and recovery rate advantages.
At JXSC Mine Machinery Factory, we've been designing these plants for over 30 years. Let's walk through a practical flow design and the real equipment cost for a Zambia alluvial gold processing plant.
Understanding Zambia's Alluvial Gold Deposits
First, know what you're dealing with. Zambia's alluvial gold is mainly found in river valleys and old terraces. The ore typically contains:
Small particle gold (50-200 microns)Some clay contamination
Occasional coarse nuggets
Magnetic minerals like magnetite (common in Zambia)
Minimal sulfide content
Because of this, a gravity-based flow is usually the best approach. No need for expensive flotation or cyanidation – simple, effective, and low-cost.
Recommended Flow Design (100TPH)
Here's a typical JXSC alluvial gold processing flow design for Zambia:
Step 1: Feeding & Washing
Feed hopper + vibrating feeder with grizzlyPurpose: Remove +150mm oversize, ensure steady feeding
Equipment: ZSW Series Vibrating Feeder
Step 2: Primary Screening & Washing
Trommel scrubber + vibrating screenPurpose: Break clay, wash off mud, classify -6mm material
Equipment: JXSC Rotary Trommel Scrubber (100TPH capacity)
Step 3: Slurry Pumping
Slurry pump transports -6mm material to concentratorsWhy: Gravity separation process requires consistent slurry density
Equipment: 4/3C-AH Slurry Pump
Step 4: Gravity Concentration
jig machines + centrifugal concentrator (optional)Purpose: Capture both coarse and fine gold
Equipment: JT Series Jig Machine (2 sets) + STLB30 Centrifugal Concentrator (1 set)
Step 5: Tailings Dewatering (optional but recommended)
Dewatering screen or hydrocyclonePurpose: Reduce water consumption, manage tailings

Note: This is FOB Xiamen/Shenzhen port price. Shipping to Zambia (via Durban or Dar es Salaam) adds approximately 30-40%. Installation and commissioning services from JXSC engineers cost extra.
Why This Flow Works for Zambia
Reason 1: High clay content handling Zambian alluvial deposits often have 10-30% clay. The trommel scrubber with high-pressure water jets effectively breaks down clay balls, preventing gold losses.
Reason 2: Fine gold recovery The combination of jig (coarse gold) + centrifugal concentrator (fine gold) achieves 90-95% recovery for -200 mesh gold. This is critical because Zambian gold is often finer than West African deposits.
Reason 3: Low operating cost Total power consumption is about 80-100kW. Jig machines use minimal water. No chemicals needed. Operating cost is approximately $1-2 per ton.
Reason 4: Easy maintenance All equipment is designed for simple maintenance. Jig screen replacement takes 30 minutes. Trommel rubber screen panels last 3-6 months.
Real Case: JXSC 100TPH Plant in Zambia
Last year, we supplied a complete 100TPH plant to a Zambian client near Ndola. Here's what they reported:
Commissioning time: 10 days (with JXSC engineer on site)Gold recovery: 92% (verified by fire assay)
Average gold grade: 0.3-0.5 g/t
Daily production: ~200-300 grams gold
Payback period: 6-8 months
Client comment: "The flow design is simple but effective. The jig machines capture everything from fine dust to nuggets. We doubled our capacity from the old 50TPH plant with no extra labor."
Common Mistakes to Avoid
Mistake 1: Skipping the scrubber Without a trommel scrubber, clay compaction causes massive gold losses. Don't try to save money here.
Mistake 2: Oversizing the concentrator 100TPH doesn't mean 100 tons going to the concentrator. After screening, only 30-50TPH (the -6mm fraction) needs processing. Oversized concentrators waste power and money.
Mistake 3: Poor water management Zambia has dry seasons. Design your water recycling system upfront. A dewatering screen alone saves 40-50% water.
Mistake 4: Ignoring security Gold processing plants attract theft. Install cameras, weigh every gold batch in front of witnesses, and keep concentrate under lock.
How JXSC Helps You Save Money
1. Modular design Our 100TPH plant comes in 3 modules: washing-classifying module, gravity concentration module, and tailings module. This reduces shipping volume and on-site installation time.
2. 1-year warranty All equipment includes free spare parts for one year: screens, rubber liners, and bearings.
3. Free flow design We don't charge for consultation. Send us your gold ore sample (2-5 kg required), and we'll design a flow with guaranteed recovery rate.
4. Remote support Even without sending engineers, our team provides video call commissioning support. Many clients save $5,000-$10,000 on travel costs.
Final Thoughts
A 100TPH alluvial gold processing plant in Zambia is a solid investment. With JXSC's proven design, you can expect:
Equipment cost: $95,000-$150,000Installation & shipping: $35,000-$60,000 (depending on location)
Production: 200-500 grams gold per day (grade-dependent)
Payback: Within 8 months under normal conditions
One piece of advice: Don't cut corners on the scrubber and concentrator. These two machines determine your recovery rate. A 5% recovery improvement can add thousands of dollars per month to your bottom line.
