Maximize Recovery Rates in Arid Environments with AuCyan™, AuCarb™, and AuLeach™
United Chemical supplies guaranteed purity AuCyan™ Sodium Cyanide NaCN (≥98.3%), AuCarb™ Gold Recovery Coconut Shell Activated Carbon (≥99% hardness), and non-hazardous AuLeach™ Gold Leaching Agent (GDA) for Heap and Vat leaching across the North African mineral belt.
1. Overcoming Metallurgical Challenges in North Africa
Gold mining operations across North Africa—from Egypt’s massive Sukari complex to Sudan's Hassai mine and Morocco’s polymetallic deposits—face unique metallurgical hurdles. High ambient temperatures, reliance on highly saline groundwater, and the presence of complex refractory ores (often high in copper or clay) severely impact leaching kinetics and Karbon adsorption.
United Chemical engineers tailored solutions to combat these exact pain points. By integrating factory-direct pricing with rigorous supply chain compliance, we ensure uninterrupted operations for Plant Managers and Metallurgists.
2. Guaranteed Purity & Ultimate Gold Recovery Solutions
Our flagship portfolio is designed to thrive under extreme operational stresses, supporting all primary extraction methods: Carbon-in-Pulp (CIP), Carbon-in-Leach (CIL), Karbon-sa-Haligi (CIC), Heap leaching, at Vat leaching.

We gladly provide free test samples of AuCarb™ Activated Carbon and AuLeach™ Gold Leaching Agent so your metallurgists can run independent bottle roll or column leach tests.
Ores in regions like Morocco often contain copper, which acts as a cyanicide. Our AuCyan™ guarantees ≥98.3% purity, ensuring aggressive leaching kinetics and minimizing the overall dosage required to overcome copper interference compared to lower-grade cyanides.
For remote sites where handling highly toxic chemicals poses extreme logistical risks, AuLeach™ GDA is the optimal choice. It provides excellent recovery rates for vat leaching while eliminating the severe security and environmental liabilities of traditional cyanide.
Carbon fines mean lost gold. AuCarb™ is manufactured from premium Baos with a strict hardness rating of ≥99% and undergoes intensive pre-attrition. This ensures maximum resistance to abrasion during the rigorous agitation of the CIP process.
