Traditionally, gold extraction relied on mercury amalgamation—a hazardous and highly pollutive method that posed environmental and health risks. The introduction of Carbon-in-Pulp (CIP) and Carbon-in-Leach (CIL) processes in the 1970s revolutionized gold recovery, making the process safer, more efficient, and environmentally sustainable. Haycarb was among the pioneering suppliers of activated carbon for this breakthrough technology, setting industry standards with our high-performance solutions. Our technically superior activated carbon products are specifically designed to meet the rigorous demands of modern gold recovery operations while offering exceptional adsorption kinetics, superior hardness, and minimal carbon losses.
Beyond our advanced manufacturing capabilities, Haycarb provides a comprehensive suite of technical services through our multidisciplinary team of chemists, process engineers, and metallurgists. Our fully equipped laboratories conduct in-depth tests and assays on activated carbon, ensuring optimal performance for every application. We also offer specialized technical support, including routine testing, process troubleshooting, activated carbon plant audits, and operator training to help customers achieve maximum efficiency in carbon selection and management. With over 50 years of expertise in activated carbon manufacturing, Haycarb has become a dominant and preferred supplier in the gold extraction industry.

CIP/CIL/CIC/Heap Leach
Manufactured under strictly controlled conditions and using environmentally sustainable technology, Haycarb’s activated carbons feature a consistent particle size distribution with minimal flaky or platelet content, an optimal pore network for maximum gold adsorption performance, and long working life in the gold carbon circuit.
Haycarb offers a variety of activated carbons made from coconut shell charcoal, engineered for carbon-in-pulp (CIP), carbon-in-leach (CIL), carbon-in-circuit (CIC), and heap leach processes. Our coconut shell-based activated carbons provide superior hardness and attrition resistance, ensuring that the carbon remains intact during the intense agitation phases in these circuits, thereby preventing gold loss due to the breakage of the loaded activated carbon that is depleted from the circuit. The optimal particle size distribution of our carbons enhances the rate of gold adsorption (R-value) and its optimal pore volume and geometry ensures maximum gold loading capacity (K-value). The high strength of the activated carbon ensures a greater number of regeneration cycles before it needs to be replaced, leading to cost-effective operations.
As a preferred supplier to the world’s leading mines, Haycarb is committed to providing total quality assurance, tailored solutions, and advancing the gold recovery process technology.
