Elevating Gold Extraction Efficiency in Sudan: Advanced Metallurgical Reagents
Conquering Arid Climates and Complex Ores with High-Purity AuCyan™ NaCN, AuCarb™ & AuLeach™ via Port Sudan
Sudan stands as one of Africa’s premier gold-producing nations, with expansive operations spanning from the Red Sea Hills to the Nubian Desert. Renowned sites such as the Hassai Gold Mine and Block 14 highlight the region's immense potential. However, metallurgical engineers and plant managers in Sudan operate under challenging conditions: extreme ambient temperatures, rapid water evaporation rates, and highly abrasive, saline ore slurries.
To maintain profitability and maximize yields across CIP, CIL, CIC, heap leaching, and vat leaching circuits, operations require chemical reagents of uncompromising quality and stability.
United Chemical is a global leader in providing factory-direct, premium gold mining chemicals. By strictly adhering to international maritime transport protocols (CIF/FOB), we deliver our flagship products securely to Port Sudan, ready for your inland truck freight. Please note our standard Minimum Order Quantity (MOQ) is 1x20' FCL.
Flagship Gold Extraction Solutions for Sudanese Mines
AuCyan™ Sodiwm Cyanid NaCN (≥98.3%)
The global standard for rapid gold complexation, formulated for extreme stability in arid, high-temperature processing environments.
Purdeb ≥98.3% heb ei gyfateb: Engineered to maximize active free sianid (CN-) release. This ultra-high purity prevents the accumulation of insoluble residues in vat leaching and CIL tanks, ensuring rapid gold dissolution even when processing challenging desert ores.
Heat & Evaporation Resilient: The rapid kinetics of AuCyan™ mean shorter required residence times in agitation tanks, which is critical in Sudan where process water evaporation is a significant operational cost.

Asiant Trwytholchi Aur AuLeach™ (GDA) - Heb fod yn Beryglus
The modern, non-hazardous alternative to traditional cyanide that drastically simplifies your import supply chain.
Strictly Non-Hazardous Classification: Because AuLeach™ is certified as non-hazardous, it bypasses complex dangerous goods permits. This significantly speeds up customs clearance at Port Sudan and lowers inland transportation insurance costs.
Seamless Drop-in Replacement: Ideal for Heap Leaching and Vat Leaching. No new equipment is required. Plant operators simply adjust the system to maintain a pH level between 10.5 11.5 a to achieve exceptional leaching kinetics comparable to traditional methods.
Strict Logistics Protocol & Transport Security
At United Chemical, we prioritize absolute safety and regulatory compliance in global chemical distribution:
FOB & CIF Ocean Freight Only: We execute secure maritime shipping direct to major hubs like Port Sudan. Please note we do not provide DDP or direct-to-site inland delivery; local forwarders must manage the final trucking leg.

Nifer Gorchymyn Isafswm: To ensure logistical efficiency and pricing benefits, our standard MOQ is strictly 1x20' FCL (Full Container Load).
Validate Performance on Your Unique Ores
We invite Metallurgists and Plant Managers across Sudan to run independent laboratory evaluations. To support your process optimization, we provide complimentary lab-scale samples of our safe-to-ship products.
⚠️ Important Safety Notice: Due to strict international aviation and security laws regarding highly toxic chemicals, AuCyan™ Sodium Cyanide NaCN cannot be shipped as a sample under any circumstances. Free samples are exclusively available for Carbon wedi'i Actifadu AuCarb™ ac Asiant Trwytholchi Aur AuLeach™.
Frequently Asked Questions: Mining Chemicals in Sudan
1. Can we transport AuCyan™, AuCarb™, or AuLeach™ via the railway system from Port Sudan?
No. Railway authorities strictly prohibit the transportation of these industrial and chemical goods. All inland logistics from Port Sudan to your mine site must be handled exclusively via heavy-duty road trucking.
2. What is your Minimum Order Quantity (MOQ) for clients in North Africa?
To guarantee the best factory-direct pricing and ensure maritime shipping safety, our strict Minimum Order Quantity for all commercial orders is 1x20' FCL (Full Container Load).
3. Why is AuCarb™ mandated to have ≥99% hardness?
In CIP and CIL agitation tanks, the carbon is subjected to intense grinding forces from the ore slurry. The guaranteed Caledwch ≥99% ensures the carbon granules do not fracture into fines, preventing your precious adsorbed gold from escaping into the tailings.
4. Does AuLeach™ Gold Leaching Agent require special hazardous goods permits in Sudan?
Rhif AuLeach™ is classified globally as a heb fod yn beryglus product. This classification avoids the complicated bureaucratic red tape, additional storage licensing, and high insurance premiums normally associated with hazardous imports at customs.
5. How do I order a free sample of AuCyan™ Sodium Cyanide to test?
For safety and legal reasons, we absolutely do not ship samples of AuCyan™ Sodium Cyanide. International aviation laws strictly forbid it. We only provide free testing samples for our AuCarb™Carbon wedi'i Actifadu ac AuLeach™ non-hazardous agent.
6. What are the operational parameters for utilizing AuLeach™ in Vat Leaching?
For optimal extraction rates during vat leaching or heap leaching, your metallurgists must monitor and maintain the solution's pH strictly between 10.5 11.5 a. This is easily managed using standard alkali agents like lime or sodium hydroxide.
7. Do you offer direct-to-site DDP delivery to mines in the Nubian Desert?
No, we operate strictly on FOB neu CIF terms for the African market. We ensure safe maritime delivery to Port Sudan. From the port, your designated local freight forwarder will handle customs clearance and overland trucking to the mine site.
8. Why is the ≥98.3% purity of AuCyan™ critical for high-temperature desert operations?
High evaporation rates in arid environments concentrate impurities in the process water. The ≥98.3% purdeb of AuCyan™ ensures you are not adding inactive salts or byproducts into your circuit, maintaining a clean chemical balance and maximizing the active cyanide available for gold dissolution.
