Activated Carbon for Gold Recovery in Tanzania — Supplier
Factory-direct coconut shell activated carbon for Tanzanian gold mines. CIP/CIL-grade specs, notes on Lake Victoria preg-robbing ores, shipping to Dar es Salaam, and 2026 pricing.
Quick answer: For Tanzanian gold recovery, use coconut shell activated carbon with iodine ≥1050 mg/g, ball-pan hardness ≥97%, and 6×12 mesh. Because many Lake Victoria–zone ores are preg-robbing, CIL with high-activity carbon protects recovery. We ship to Dar es Salaam in 30–40 days, FOB from $3,200/ton, MOQ 1 container (5-ton trials available).
| Parameter | CIP / CIL Spec | Why It Matters in Tanzania |
|---|---|---|
| Iodine Number | ≥1050 mg/g | High gold loading capacity for preg-robbing Lake Victoria ores |
| Ball-Pan Hardness | ≥97% | Survives abrasive CIL circuits, low fines and gold-room losses |
| Particle Size | 6×12 mesh (CIP), 6×16 (CIL) | Screens cleanly; finer mesh boosts CIL adsorption kinetics |
| CTC Activity | ≥55% | Confirms developed pore structure for fast gold pickup |
| Moisture | <5% | You pay for carbon, not water — we ship at 3–5% |
| Ash Content | <3% | Cleaner elution and gold smelting downstream |
Tanzania's Gold Belt and What It Means for Carbon
Tanzania is one of Africa's top gold producers, with output concentrated in the Lake Victoria Greenstone Belt — Geita, Bulyanhulu, North Mara, and the Shinyanga–Mwanza corridor. These deposits keep the country among the continent's largest producers, and nearly every operation relies on activated carbon for gold adsorption.
The key characteristic here: many Lake Victoria–zone ores contain organic carbon and carbonaceous material that can cause preg-robbing — where native carbon in the ore steals dissolved gold from solution before your recovery carbon can adsorb it. This makes CIL (Carbon-in-Leach) the preferred process over straight CIP, because leaching and adsorption happen simultaneously and the added carbon out-competes the ore's natural carbon.
For preg-robbing circuits, carbon activity and hardness matter even more. Low-grade carbon loses the competition for gold and breaks down faster under the extended residence times of CIL.

Recommended Carbon for Tanzanian CIP/CIL
We recommend our coconut shell activated carbon for Tanzanian gold recovery. It outperforms coal-based carbon in hardness, gold loading, and elution efficiency — the differences that decide profitability in a preg-robbing CIL circuit. See our 6×12 gold carbon specifications guide for a full breakdown of what each COA line means, and the coconut shell gold extraction guide for process fit.
Shipping to Tanzania: Ports, Lead Time & Logistics
Dar es Salaam is the primary gateway for Tanzanian mines. From our factory to port, expect the following:
- • Sea transit (Ningbo/Shanghai → Dar es Salaam): 20–25 days
- • Total lead time (production + docs + shipping): 30–40 days
- • Inland trucking to Geita, Mwanza, or Shinyanga: 2–4 days from port
- • Packaging: 500 kg jumbo bags (forklift-friendly) or 1 MT super sacks, PE-lined and moisture-proof
Pro tip: Order 60–90 days ahead of your carbon change-out schedule. We keep safety stock allocated for African mining customers to prevent supply gaps, and we handle transit documentation for customs clearance at Dar es Salaam.
2026 Pricing & MOQ for Tanzania
Pricing Guide (FOB Ningbo/Shanghai)
- • Gold recovery coconut shell (6×12, iodine 1050+): $3,200–$3,800/ton
- • Gold recovery coconut shell (6×16, iodine 1000+): $3,200–$3,600/ton
- • Mine water treatment coal-based GAC (8×30): $800–$1,400/ton
CIF Dar es Salaam adds roughly $60–$120/ton over FOB.
MOQ: 1 container (18–20 tons) for standard specs. 5-ton trial orders available for new customers benchmarking our carbon.
Payment: T/T (30% deposit + 70% against B/L) or irrevocable L/C at sight. Every shipment includes a COA tested in our lab, with SGS or Bureau Veritas verification on request.
Delivery Track Record in East Africa
We've supplied gold recovery carbon across East Africa for over a decade, including a Tanzanian CIL operation in the Lake Victoria zone that switched to us in 2019 for preg-robbing ore. Recent regional shipments show our export reliability:
- • 56 tons of gold recovery carbon shipped to Ethiopia — loading inspection case study
- • 28 tons of gold recovery carbon shipped to Egypt
- • Africa-wide mining sourcing guide — specs, ports, and logistics across the continent

Frequently Asked Questions
What activated carbon spec is best for Tanzanian gold CIL circuits?
Coconut shell activated carbon with iodine number ≥1050 mg/g, ball-pan hardness ≥97%, 6×12 mesh, and moisture <5%. Many Tanzanian ores around Lake Victoria carry organic carbon with preg-robbing potential, so CIL with high-activity carbon protects gold recovery.
How long does shipping activated carbon to Tanzania take?
Sea transit from Ningbo/Shanghai to Dar es Salaam runs 20–25 days, with a total lead time of 30–40 days including production and documentation. Inland delivery to Geita, Mwanza, or Shinyanga mine sites adds a few days of trucking.
What is the minimum order for Tanzania gold mines?
MOQ is 1 container (18–20 tons) for standard specs. We offer 5-ton trial orders for new customers who want to benchmark our coconut shell carbon against their current supplier before committing to quarterly replenishment.
