Carbon-in-Leach (CIL) Systems
Simultaneous cyanidation leaching and activated carbon adsorption engineered for high-recovery processing of preg-robbing, organic carbon, and clay-rich gold ores.
Why standard off-the-shelf solutions fail in mining.
Ores containing naturally occurring organic carbon or reactive clays suffer from severe preg-robbing if leaching occurs prior to carbon contact, irreversibly locking dissolved gold in tailings.
Our Engineering & Delivery Approach
We combine analytical process modeling with hands-on site metallurgy to achieve verified operational results.
Simultaneous cyanide dissolution and carbon adsorption to outcompete natural mineral preg-robbers instantly.
Optimize counter-current carbon concentration profiles across tanks (12 to 20 g/L) to maximize gold loading kinetics.
Automated dissolved oxygen sparging and cyanide dosing controls to maintain steady cyanide leach kinetics.
Turnkey mechanical and electrical installation with robust HSE cyanide containment protocols.
