High salinity can impact adsorption kinetics. However, AuCarb™ is engineered with a highly developed microporous structure and ≥99% hardness, maintaining superior gold loading capacity and resisting fouling even in brackish water common in Saharan operations.
Yes. AuLeach™ is specifically formulated for Heap Leaching and Vat Leaching. It acts as a direct, non-hazardous replacement for NaCN, utilizing the same spray systems while drastically reducing environmental monitoring and transportation costs.
We manage full end-to-end compliance. AuCyan™ is shipped in UN-certified packaging (plywood boxes or steel drums) via strictly vetted shipping lines. We handle all MSDS, dangerous goods declarations, and export permits. MOQ is 1x20' FCL.
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 sianida.
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 Shell kelapas 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.
