Carbon Specifications for Sudan Gold Mining
Sudan’s distinctive mix of CIL, heap leach, and tailings retreatment demands carbon with exceptional mechanical strength and high gold-loading capacity. Below are the specs we ship to Sudanese operations.
| Parameter | Value | Why It Matters |
|---|---|---|
| Iodine Number | ≥1100 mg/g | High gold loading from dilute heap-leach solutions |
| Ball-Pan Hardness | ≥98% | Survives hard cycling in tailings-retreatment circuits |
| Mesh Size | 6×12 (CIL) / 6×16 (heap leach) | Coarser for pulp pumping; finer for percolation columns |
| CTC Activity | ≥55% | Fast kinetics for pregnant leach solution |
| Ash Content | <3% | Cleaner elution with Sudan's hard, saline process water |
| Moisture | <5% | Shipped at 3–5% — you pay for carbon, not water |

Gold Recovery Applications in Sudan
Sudan is one of Africa’s top-three gold producers, with almost all output from the Neoproterozoic Nubian Shield along the Red Sea Hills. From flagship CIL plants to artisanal tailings dumps being reprocessed through carbon columns — we match the right grade to each circuit.
CIL Gold Plants
Carbon-in-leach circuits processing oxide ore from the Red Sea Hills and Nubian Shield. Our 6×12 coconut carbon delivers high gold loading and minimal attrition in agitated tanks.
Heap Leach & CIC Columns
Tall carbon columns treating pregnant solution from large-tonnage heap-leach pads. Hardness ≥98% keeps head loss low and prevents channelling from fines.
Tailings Retreatment
Reprocessing decades of artisanal mining dumps through CIP/CIL — where carbon cycles fast through smaller, high-turnover circuits that punish weak carbon.
Mine Process Water
Coal-based GAC for treating mine water and camp potable supply — removes organics, residual cyanide, and turbidity.

Sudan’s Real Carbon Challenge
Reprocessing Artisanal Mercury-Amalgamation Tailings
Sudan is one of Africa’s largest gold producers, and a huge share of its output comes from artisanal and small-scale mining (ASGM). For years that gold was won by mercury amalgamation, leaving behind vast tailings dumps that still hold most of their gold. Those dumps are now being cyanide-leached through CIP/CIL and carbon-in-column plants — and that reprocessed feed attacks carbon in ways a fresh hard-rock ore never would. This is the differentiator for Sudan: the carbon has to survive fast-turnover tailings circuits carrying residual mercury, fine clay, and carbonate.
How Artisanal-Tailings Feed Tests the Carbon
| Factor | Effect on the Carbon Circuit | How We Address It |
|---|---|---|
| Residual mercury in tailings | Mercury co-adsorbs onto the carbon alongside gold, competing for sites and complicating elution and thermal reactivation | High-activity coconut carbon (iodine ≥1050) preserves gold loading despite mercury competition; low ash keeps regeneration cleaner |
| Fast-turnover retreatment circuits | Reprocessing plants cycle carbon 2–3× faster than conventional CIL, so weak carbon sheds fines and gold to tailings quickly | Ball-pan hardness ≥98% and A.A.R.L. attrition ≤2% hold mass through many more load-strip-reactivate cycles |
| Fine clay & slimes in old dumps | Clay fouls and blinds carbon surface, cutting effective loading between changeouts | Hard, low-fines granules resist blinding and screen cleanly; correct 6×12 mesh keeps interstage screening efficient |
| Carbonate / hard process water | Calcium carbonate scales the carbon and blinds pore mouths, dragging down loading capacity over the season | Low-ash (<4%) carbon plus acid-wash ahead of reactivation strips scale and restores activity |

Why Hardness Is Everything in Sudan
Decades of artisanal mining created enormous tailings dumps now being reprocessed through CIP/CIL. These smaller, high-turnover circuits cycle carbon 2–3× faster than conventional CIL — punishing any carbon below 98% hardness with excessive attrition and fines loss.
Our coconut shell 6×12 maintains structural integrity across 20+ elution cycles, keeping your make-up carbon cost low and your screens clear.

Sudan Gold Recovery Carbon FAQ
What carbon spec works for Sudan CIL and heap-leach gold recovery?
Coconut shell activated carbon with iodine ≥1100 mg/g, ball-pan hardness ≥98%, 6×12 mesh for CIL, and 6×16 for heap-leach carbon columns (CIC). Sudan's mix of oxide ore CIL and large-tonnage heap leach rewards hard, low-fines carbon.
Why is residual mercury a concern when reprocessing artisanal tailings in Sudan?
Decades of mercury amalgamation across Sudan's artisanal sector left tailings containing free mercury and mercury-gold amalgam residues. When those tailings are cyanide-leached in a CIP/CIL plant, mercury dissolves alongside gold and co-adsorbs onto the carbon, occupying active sites and complicating thermal reactivation (mercury must be retorted off before the carbon enters the kiln). High-activity coconut carbon (iodine ≥1100) preserves enough spare adsorption capacity to hold gold loading despite mercury competition.
How long does shipping to Port Sudan take from China?
Sea transit from Ningbo/Shanghai to Port Sudan on the Red Sea is 22–30 days via the Bab-el-Mandeb strait, with total lead time of 35–50 days including production and Red Sea routing contingencies.
Do you supply artisanal tailings-retreatment plants in Sudan?
Yes. Beyond large CIL plants, we supply CIP/CIC plants reprocessing artisanal tailings. Consistent hardness matters most because carbon cycles hard through smaller, high-turnover circuits. 5-ton trial orders are available.
What is the pricing for gold recovery carbon shipped to Sudan?
FOB Ningbo: $3,200–$3,800/ton for coconut shell 6×12 (iodine 1100+). CIF Port Sudan adds roughly $90–$170/ton depending on Red Sea routing at time of booking. Payment via T/T or L/C at sight.
What packaging do you use for Sudan shipments?
500 kg jumbo bags or 1 MT super sacks, PE-lined and heat-sealed against Red Sea humidity and desert dust during the Port Sudan–to–mine haul.
