Precious Metal Refineries

Profit loves predictability.

Selective PGM and precious metal recovery that holds when feeds vary.

Stabilize recovery where it’s most volatile: side/waste/bleed streams, anode-slime circuits, and mixed PGM feeds. Elmery’s pulse-based electrochemistry delivers fast and selective recovery with fewer chemicals and fewer steps, built for real-plant variability.

Where Elmery fits → What you gain

Common challenges →	Impact →	What you gain with Elmery
Valuable metals left in waste/side/bleed streams	Direct value lost	Increased value with selective precious metal recovery
Slow metal recovery and needlessly long process loops	Operational bottlenecks & increased lease rate costs	Fast, targeted electrochemical recovery that shortens cycles and improves process efficiency
Suboptimal metal recovery or purity	Lost value with a lower product quality	High-purity metal recovery with precise, controllable selectivity
Multiple unit operations required	Increased maintenance & complexity	One integrated recovery step that reduces unit operations
Heavy use of chemical reagents	Safety risks & higher operating cost	Chemical-free recovery using only electricity

Why this matters

Valuable metal left in side streams is value down the drain— often at the highest prices in your process. Variable composition makes purity and yield swing, creating uncertainty in both output and planning. Slow or inefficient recovery ties up capital in inventory, increases lease rate costs, and creates operational bottlenecks. Chemical spend adds operating cost, safety burden, and supply-risk exposure.

Elmery targets the low-concentration losses, tunes for stability, and cuts chemical demand by design so your downstream stays predictable.

What you get

Consistent selectivity, even with variable compositions (PGMs / Au / Ag / others as scoped).
Chemical-free recovery, reducing cost, handling, and compliance load.
Fast kinetics that shorten circulation times and reduce tied-up inventory.
High-purity recovery that increases product value and simplifies downstream refining.

Chemistry contexts we handle

Chloride, ammonia systems (PGM operations)
Sulphate, nitric contexts common in anode slime treatment

FAQ

Will it handle ppm ranges?
Yes. Built for dilute, mixed feeds.
Do we need to rip and replace?
No. Elmery can operate with our own recovery cell or seamlessly integrate into your existing electrowinning setup. Your current cell, cathodes and anodes can be reused — all that’s needed is a new power source.
Pilot timeline?
Typically weeks, stream-dependent.
