Solucións químicas para a minería global: potenciando a extracción de ouro en máis de 77 países

At United Chemical , we do not just manufacture chemical reagents; we engineer high-recovery, cost-effective metallurgical solutions for the world's most demanding gold mining regions. With a robust export footprint spanning over Máis de 77 países e rexións , we are the trusted supply chain backbone for top-tier gold mines, from massive CIL plants to high-altitude heap leach operations.

Based on decades of international trade expertise, we understand that supply chain stability, chemical purity, and environmental compliance are the lifelines of any mining operation. That is why we secure maximum gold yield through our core product lineup:

• ⚫ AuCarb™ (High-Hardness Coconut Shell Activated Carbon): A premium series featuring four specialized product grades engineered to perfectly cover all global gold extraction methodologies—including Carbon-in-Pulp (CIP), Carbon-in-Leach (CIL), VAT Leaching, Gold ore heap leaching, and Carbon-in-Column (CIC) operations. Test samples of the high-hardness Concha de coco gold extraction activated Carbono están dispoñibles. (Free test samples available upon request).

• 🟢 AuLeach™ (Eco-Friendly Gold Leaching Agent):  Our highly efficient alternative reagent, developed for regions where cianuro use is  restricted or the End-User Certificate (EUC) processes are very complex,  is non-toxic, and its transportation and customs clearance are treated as normal chemicals. (Free test samples available upon request).

• 🟡 AuCyan™ Sodium Cyanide (98.3% Min): This is our primary reagent, produced in high-purity briquette  (solid block) form to international standards, for industrial gold leaching processes (CIP/CIL/VAT/Heap Leaching). Legal import permits and End-User Certificates (EUC) from the relevant ministries are mandatory for this product.

🗺️ Our 11 Dominant Global Supply Hubs

To provide localized support and efficient shipping routes, we have strategically mapped our global operations into 11 core dominant regions, encompassing 72 primary target countries.

1. The African Gold Engine (West, East, Southern, Central & North Africa)

Africa remains the undisputed powerhouse of global gold production. Our supply network covers the dense greenstone belts of África Occidental (Ghana, Mali, Burkina Faso, Côte d'Ivoire, Guinea), the deep-level mining and tailings retreatment hubs of África Austral (South Africa, Zimbabwe), as well as emerging and established operations across East, Central, and North Africa (including Tanzania, DR Congo, Egypt, and Sudan).

• A nosa solución: We supply thousands of tons of AuCyan™ Sodium Cyanide NaCN (≥98.3%) alongside our highly durable activated carbon.

• Loxística fiabilidade: Given the complexities of African inland transit, all our shipments are strictly managed under transparent FOB  and CIF terms . We secure your ocean freight to major African ports, allowing your local experts to handle inland logistics smoothly.

2. The Americas: Eco-Compliance & High Yields (South America, Central America & Caribbean)

Spanning from the high-grade porphyry deposits of Peru, Brazil, and Mexico to the highly regulated environmental zones of Colombia and French Guiana , the Americas demand both high efficiency and strict compliance.

• nosa Solución: For regions with stringent environmental regulations, our Axente de lixiviación de ouro ecolóxico AuLeach™ (GDA) is  the ultimate game-changer. It is a completely non perigosos  eco-friendly alternative to traditional cyanide, allowing mines to operate      smoothly without facing strict DG (Dangerous Goods) hurdles.

3. Russia, CIS & Central Asia: High-Altitude & Complex Ore Reliability

Supplying the mining giants of Russia, Kazakhstan, Uzbekistan, Tajikistan, and Kyrgyzstan requires reagents capable of handling complex, refractory, and polymetallic ores.

• nosa  Solución: We provide ultra-high-purity AuCyan™  Sodium Cyanide NaCN (≥98.3%) to significantly minimize side reactions with base metals like copper. All shipments to this region are strictly executed via secure ocean-to-road multimodal transport under FOB ou CIF condicións .

4. Southeast Asia: Tropical Climate & High-Clay Ores

Operating in tropical archipelagos like Indonesia, the Philippines, Myanmar, and Laos involves processing highly viscous clay ores where soft Carbón activado easily degrades, causing catastrophic gold loss.

• nosa  Solución: nosa AuCarb™ Gold Recovery coconut shell activated carbon boasts a rigorous ball-pan hardness of ≥% 99 , effectively resisting severe abrasion in vigorous CIP/CIL circuits.

5. Middle East & West Asia: The New Mining Frontiers

Backed by significant investments and modern infrastructure, countries like Saudi Arabia, Türkiye, and Iran are rapidly expanding their gold extraction capabilities. We support these state-of-the-art facilities with premium, high-purity chemical reagents tailored for large-scale heap leaching and CIL processes.

💡 Frequently Asked Questions (Global Procurement & Technical Support)

As a global procurement manager, certainty is your top priority. Here are the most frequently asked questions regarding our international chemical supply:

Q1: How many countries does United Chemical actively export to? We currently export to and service Máis de 77 países e rexións globally. Our core operations are strategically focused across 11 dominant regions, deeply covering the African continent, the Americas, Central/Southeast Asia, and the Middle East.

Q2: What are your standard shipping and trade terms for complex regions like Africa and Russia? To ensure the highest level of safety, transparency, and cost-effectiveness, all our international shipments (especially to Africa, Russia, and Central Asia) are conducted strictly under FOB (Free On Board) or CIF (Cost, Insurance, and Freight) terms via ocean freight. (Please note: Due to strict international dangerous goods regulations, we do not utilize railway transport for our chemical products. Ocean freight ensures maximum safety and compliance).

Q3: What makes your Sodium Cyanide stand out for complex polymetallic gold ores? nosa AuCyan™ Sodium Cyanide NaCN (≥98.3%) guarantees an exceptionally high baseline purity. This is critical when leaching polymetallic ores (containing high levels of copper or zinc). Higher purity significantly reduces wasteful side reactions, thereby lowering your overall reagent consumption per ton of ore.

Q4: My country has strict bans on Sodium Cyanide. Do you have a compliant alternative? Absolutely. For regions with stringent environmental laws (such as Colombia or parts of Europe), we supply the Axente de lixiviación de ouro ecolóxico AuLeach™ (GDA) . It is a completely non perigosos , eco-friendly alternative to Cianuro de sodio. It simplifies your import process, eliminates the need for complex DG permits, and protects the local environment without sacrificing your gold recovery rates.

Q5: How does your Activated Carbon perform in high-attrition CIP/CIL tanks? Carbon abrasion leads directly to unrecoverable gold loss in tailings. Our AuCarb™ Gold Recovery Carbón activado de casca de coco is engineered with a strict ball-pan hardness of ≥% 99 . This exceptional structural integrity prevents carbon breakdown and "pinning" even in the most vigorous agitation tanks or clay-heavy ore environments.

Q6: How do you ensure the safe international shipping of chemical reagents? Safety is non-negotiable. We strictly adhere to the International Maritime Dangerous Goods (IMDG) regulations. Our products are packed in UN-certified robust packaging—such as 50kg steel drums or 1,000kg wooden boxes with high-density inner liners—ensuring zero leakage during long-haul sea transit.

Q7: What is the Minimum Order Quantity (MOQ) for international procurement? To optimize your ocean freight costs and ensure safe container stuffing, our standard MOQ is one 20-foot Full Container Load (FCL). Depending on the specific product, this ranges from approximately 10 to 18 Metric Tons per container.

P8: Pode United Chemical assist with export documentation and customs clearance support? Yes. Our international trade department provides a comprehensive suite of export documents required for your CIF/FOB shipments. This includes the Certificate of Origin (COO), Commercial Invoices, Packing Lists, Safety Data Sheets (MSDS), and relevant third-party inspection reports to expedite your local port clearance.
