The Golden
Triangle

Three reagents, one complete gold recovery circuit — leaching, adsorption and eco-friendly substitution across CIP, CIL, CIC, Heap and Vat leaching plants.

The Circuit

Three control points on one metallurgical flow sheet. Each product solves a different failure mode in the recovery circuit.

STAGE 01 / DISSOLUTION

Leaching

AuCyan™ Sodium Cyanide NaCN (≥98.3%)

High-purity briquettes deliver maximum free cyanide ion availability for rapid gold dissolution kinetics.

STAGE 02 / CAPTURE

Adsorption

AuCarb™ Gold Recovery Coconut Shell Activated Carbon (≥99% Hardness)

Abrasion-resistant coconut shell carbon limits attrition and the gold-bearing fines that leave with the tailings.

STAGE 03 / COMPLIANCE

Substitution

AuLeach™ Gold Leaching Agent (GDA) - Non-Hazardous

A general-cargo alternative developed for markets where cyanide permits or end-user certificate procedures are complex.

Applicable metallurgy processes

Carbon-in-Pulp (CIP)  ·  Carbon-in-Leach (CIL)  ·  Carbon-in-Column (CIC)  ·  Heap leaching  ·  Vat leaching

01 / Leaching
White sodium cyanide briquettes in bowls, sealed steel drums and wooden export crates at the United Chemical plant
Briquette form  ·  UN 1689

AuCyan™ Sodium Cyanide NaCN (≥98.3%)

White, solid briquettes with a guaranteed minimum purity of ≥98.3%. Low unreacted sodium hydroxide limits scale formation in high-hardness process water, while low insoluble content protects pumps and nozzles. Supplied in UN-certified export packaging under full maritime DG Class 6.1 protocols.

02 / Adsorption
AuCarb coconut shell activated carbon: black granules, macro texture, branded black and gold cartons, and sample jars of carbon
Four dedicated grades

AuCarb™ Gold Recovery Coconut Shell Activated Carbon (≥99% Hardness)

Coconut shell granular carbon in four dedicated grades — BC1100, AC50, AC55 and AC60 — built for high-shear agitation circuits. A controlled micropore-to-mesopore ratio gives fast uptake of gold-cyanide complexes, while ≥99% ball-pan hardness resists the breakdown that carries loaded gold into tailings.

Solid powder  ·  General cargo

AuLeach™ Gold Leaching Agent (GDA) - Non-Hazardous

A solid-powder leaching reagent with 30% active concentration and an operating pH of 10.5–12. Developed for operations where cyanide storage compliance, import licensing or EUC lead times are the constraint. Compatible with existing CIP / CIL equipment, and shipped as general cargo.
