Soluções integradas para extração de ouro no setor de mineração do Níger

Niger's gold mining industry is rapidly expanding, driven by rich deposits in the Liptako region (Téra department) and the remote Djado Plateau. As operations scale up from artisanal activities to industrial CIL (Carbon-in-Leach) and heap leaching plants, the demand for highly efficient, stable, and compliant metallurgical reagents is critical.

United Chemical is a premier international partner for Nigerien gold producers. We deliver a comprehensive portfolio of high-purity gold recovery chemicals, backed by flexible global shipping terms designed to seamlessly navigate the logistical realities of landlocked West Africa.

Our Flagship Reagents for Nigerien Gold Circuits

1. AuCyan™ NaCN Sodium Cyanide ≥98.3%

For industrial-scale cyanidation plants processing oxidized ores from the Liptako greenstone belts, AuCyan™ NaCN Cianeto de Sódio ≥98.3% remains the industry standard. Manufactured to yield virtually zero insoluble impurities, it guarantees aggressive dissolution kinetics. This ensures plant metallurgists can maintain precise dosing control, reduce overall chemical consumption, and maximize extraction rates across continuous operating cycles.

2. AuCarb™ Gold Recovery Coconut Waterfall Activated Carvão

In demanding CIL/CIP environments, the physical durability of your activated Carbono directly impacts your profitability. AuCarb™ Gold Recovery Carvão Ativado de Casca de Coco is engineered with an independently verified ball-pan hardness of ≥ 99% . This ultra-high attrition resistance prevents carbon breakdown during intense mechanical agitation, ensuring that adsorbed gold remains locked in the pores and is not lost to the tailings stream.

3. AuLeach™ - Agente de Lixiviação de Ouro Ecológico (GDA)

For landlocked nations like Niger, importing highly toxic chemicals involves complex transit permits through neighboring countries. AuLeach™ - Agente de Lixiviação de Ouro Ecológico (GDA) offers a strategic advantage. As a non-hazardous, cianeto-free replacement, it delivers equivalent leaching kinetics while completely bypassing the stringent Dangerous Goods (DG) transit restrictions, accelerating cross-border logistics and eliminating cyanide toxicity from mine tailings.

Strategic West African Logistics: FOB & CIF Expertise

We understand that securing a reliable chemical supply chain into Niger requires specialized international logistics, as cargo must transit through major West African coastal gateways.

United Chemical offers flexible Incoterms to align with your procurement strategy:

• FOB (Main China Ports): We handle all domestic regulatory approvals, DG inspections, and container loading  at major Chinese export hubs, providing you with complete documentation for your nominated freight forwarders.

• CIF (Gateway Ports for Niger): We manage ocean freight and marine insurance directly to the primary transit ports for Niger—specifically the Port of Cotonou (Benin) e Port  of Lomé (Togo) . From there, your local logistics partners can arrange final overland transit to mine sites in Niamey or Téra.

• IMDG-Compliant Packaging: AuCyan™ NaCN Sodium Cyanide ≥98.3% is packaged in UN-certified steel drums or heavy-duty wooden      boxes housed in sealed marine containers, ensuring compliance with      international maritime safety codes.

Perguntas frequentes

Q1: What are the primary shipping routes for United Chemical products to Niger?

Because Niger is landlocked, we rely on standard West African maritime gateways. Under our CIF terms, we ship primarily to the Port of Cotonou (Benin) ou de Porto de Lomé (Togo) . Upon arrival, we provide full commercial and hazardous goods documentation (MSDS, COA) so buyers can smoothly clear customs and execute overland trucking to their facilities in Niger.

Q2: Why is AuLeach™ GDA highly recommended for landlocked countries like Niger?

Transporting traditional Cianeto de sódio across international borders (eg, from Benin into Niger) requires extensive Dangerous Goods (DG) transit permits, armed escorts, and specialized trucking, which causes delays and spikes costs. AuLeach™ - Agente de Lixiviação de Ouro Ecológico (GDA) is non-hazardous. It avoids these regulatory bottlenecks entirely, resulting in faster import times, lower freight costs, and safer handling at the mine site.

Q3: How does AuCarb™ Activated Carbon perform in high-agitation circuits?

Extremely well. To prevent soluble gold from escaping into the tailings, the carbon must withstand the aggressive shear forces of mechanical impellers in CIL/CIP tanks. AuCarb™ Gold Recovery Carvão Ativado de Casca de Coco boasts an industry-leading hardness of ≥ 99% , significantly reducing attrition rates and ensuring your final gold yield is securely retained throughout the elution cycle.
