United Chemical’s newly developed premium gold recovery coconut shell activated carbon series (including BC1100, AuCarb™ AC50, AC55, and AC60) is engineered specifically for global metallurgical recovery networks. Our products deliver exceptional operational stability across diverse extraction frameworks, including aggressive Carbon-in-Pulp (CIP) and Carbon-in-Leach (CIL) circuits, high-volume Carbon-in-Column (CIC) loops, as well as complex Gold Ore Heap Leaching and continuous VAT Leaching / Tank Leaching facilities. Featuring outstanding mechanical hardness, an ultra-dense sub-nanometer microporous matrix, and highly optimized gold loading kinetics, our activated Carbon effectively minimizes gold lock-up, limits carbon fines degradation, and drastically cuts soluble gold losses under the most rigorous, high-attrition mining environments worldwide.

Brand Introduction: Outstanding Gold Recovery Solutions

Shaanxi United Chemical CO., Ltd. stands proudly as China’s leading provider of gold mining chemicals and comprehensive engineering technology solutions. Our exceptional products and services have established a robust global footprint, covering over 77 countries and effectively supporting more than 200 major mining facilities worldwide.

To ensure long-term, superior performance when processing a wide variety of complex ores, we have specially engineered and developed the AuCarb™ series of premium, renewable granular microporous Activated Carbon. Exclusively tailored for highly efficient gold recovery processes (CIL & CIP), this series is strongly recommended for the initial filling of recovery circuits. It not only guarantees exceptional gold recovery rates but also significantly reduces activated carbon inventory losses.

To assist clients of varying production scales and ore grades in rapidly identifying the perfect fit, we have meticulously curated the following four core product lines: BC1100, AC50, AC55, and AC60.
