Gold Mining
From heap leach pads to mill circuits, activated carbon is the cornerstone of precious metal recovery. R3 Carbons provides high-hardness, high-capacity reclaimed wood-based carbons designed to withstand the rigorous mechanical and chemical conditions of gold adsorption and regeneration. Our solutions help operations worldwide boost yield, extend media life, and maintain environmental responsibility—because in gold recovery, every ounce matters.
Recover Every Ounce. Refine Every Circuit.
R3 Carbons activated carbon is engineered for maximum gold recovery in Carbon-in-Column (CIC), Carbon-in-Pulp (CIP), and Carbon-in-Leach (CIL) systems—delivering consistent performance, minimal losses, and reliable reactivation cycles.
Carbon-In-Column
In Carbon-in-Column systems, gold cyanide solutions pass upward through fluidized columns packed with activated carbon. HydroSorbR™ Gold grades are optimized for fast kinetics and abrasion resistance, allowing efficient recovery even from solutions containing 2–3% solids. Ideal for heap leach operations, these carbons maintain strong mechanical integrity through multiple regeneration cycles.
R3 Carbons’ high-activity wood-based GAC provides rapid gold capture, low attrition, and high stripping efficiency. Uniform pore activation ensures predictable performance and minimal screen blinding, while our technical team supports column design, carbon handling, and carbon reactivation programs—keeping recovery continuous and dependable.
Carbon-In-Pulp
In Carbon-in-Pulp circuits, finely ground ore and cyanide leach slurry are mixed with activated carbon, allowing gold adsorption directly from pulp. R3 Carbons’ GAC grades are engineered for fast kinetics and exceptional hardness, reducing fines formation and maximizing gold recovery throughout the multi-tank process.
Our carbons maintain strong loading capacities across multiple adsorption–desorption–regeneration (ADR) cycles, ensuring consistent yield and minimal carbon losses. Optimized particle sizing prevents peg-out, while uniform pore structure promotes effective diffusion of gold cyanide complexes—making HydroSorbR™ Gold the trusted choice for high-throughput CIP operations.
Carbon-In-Leach
The Carbon-in-Leach process combines gold dissolution and adsorption in one step, allowing carbon to capture gold as it forms in solution. R3 Carbons’ high-performance grades are formulated to preferentially adsorb gold even in ores containing native carbon or organic matter, preventing “preg-robbing” and improving total metal recovery.
With excellent abrasion resistance, high activity, and fast adsorption kinetics, our carbons deliver reliable performance across intensive CIL operations. From acid washing to reactivation, R3 Carbons provides complete process guidance to help operators maintain purity, reduce carbon breakage, and optimize leach circuit efficiency.
All Metals
R3 Carbons’ expertise extends beyond gold. Our activated carbon and ion exchange technologies support recovery of copper, nickel, zinc, uranium, and other metals from ore, waste, and reclaimed streams. These systems are built on proven adsorption and separation principles that maximize yield and reduce chemical use.
Our modular systems scale from pilot to production, offering consistent, high-purity outputs while minimizing waste and downtime. R3 Carbons’ reactivation and engineering support ensure sustainable operation and lower lifecycle costs—helping producers extract more value from every resource.
Maximize Recovery. Minimize Loss.
From heap leach to high-grade mill circuits, R3 Carbons delivers the performance, durability, and technical partnership that modern gold recovery demands. Our high-hardness, reclaimed wood-based activated carbons are engineered for exceptional kinetics, long life, and sustainable reactivation—ensuring every ounce counts.
