Non-cyanide gold leaching and stripping chemistry
Selective non-cyanide gold chemistry for industrial recovery operators.
A complete gold-recovery stack. Stripping uses an electrolytic process to recover gold in solid form straight from waste — no precipitation step. Non-cyanide leaching dissolves gold from complex feedstocks for downstream precipitation. Both leave the base metal intact, so refining is cleaner and cheaper.
Products in this family
Selectively strips gold layers from base-metal substrates using an eco-friendly electrolytic process — no cyanide, recovers gold directly in solid form with no precipitation step required.
Dissolves gold from complex feedstocks into solution for downstream precipitation. Non-cyanide formulation — easier permitting and effluent handling.

Frequently asked
No. Our flagship gold-leaching chemistry is a non-cyanide formulation engineered to give comparable yield without the regulatory and effluent burden of cyanide.
Stripping recovers gold in solid form directly from the substrate using an electrolytic process — no precipitation step. Leaching dissolves gold into solution using non-cyanide chemistry for downstream precipitation. Operators run one or both depending on feedstock.

For operators evaluating a move away from cyanide, our non-cyanide gold leaching guide covers the real operational trade-offs: speed, selectivity, effluent classification and feed preparation requirements.
Feed chemistry varies significantly between PCB, bonding wire and jewellery scrap. PolyGO can run a bench-scale feasibility trial on your feedstock before you commit to a chemistry — at no cost.
