MINING OPERATORS
The best tonne is the one you already moved.
Selective recovery and impurity removal from process streams across mining and hydrometallurgical operations.
Mining operations move, process and manage enormous material flows. Yet valuable metals can remain dissolved in process streams, while unwanted elements continue circulating through the plant. Elmery helps recover target metals and remove problem elements from liquid streams – improving overall recovery, stabilizing downstream processes and reducing treatment complexity.
Where Elmery fits → What you gain
| Common challenges → | Impact → | What you gain with Elmery |
|---|---|---|
| Valuable metals left in leachates, process waters, raffinate or bleed streams | Lost value after the material has already been mined and processed | Targeted recovery of dissolved metals from side and process streams |
| Hazardous or unwanted elements such as arsenic, selenium or lead | Compliance risk, waste-management cost and environmental burden | Selective removal of harmful elements before they create processing or downstream problems |
| Difficulty in recovering specific metals | Value of those metals lost | Specific recovery parameters for selective extraction of challenging or low-availability metals |
| Variable stream chemistry | Unstable treatment performance and process uncertainty | Pulse-based control tuned to defined stream conditions |
| Dependence on chemical reducing agents | Higher reagent cost, sludge generation and handling complexity | Low-chemical electrochemical treatment using electricity as the main input |
Why this matters
Mining already carries the cost of extraction, transport, grinding, leaching and water management. When valuable metals remain in liquid streams, or when harmful elements keep circulating, the site pays twice: once in lost value and again in treatment complexity.
Elmery adds a selective electrochemical step to the existing hydrometallurgical circuit. It targets metals already dissolved in solution, helping recover saleable value, remove selected impurities and reduce the load on downstream operations. Laboratory and pilot work establish performance and the industrial business case before full-scale deployment.
What you get
- Higher overall recovery from material that has already been mined and processed.
- Selective separation of target metals from complex, mixed-metal solutions.
- Targeted impurity removal of harmful elements from process, side and waste streams..
- Fewer process steps and safer handling — no added chemicals.
- Modular integration into existing hydrometallurgical and electrowinning circuits.
- A controlled path to scale: sample → laboratory validation → on-site pilot → industrial service.
Chemistry contexts we handle
- Mine process waters, leachates, filtrates, raffinate and bleed and recycle streams.
- Sulphate, chloride, nitric and ammonia-based systems.
- Concentrations ranging from ppm levels to hundreds of grams per litre.
- Streams containing dissolved valuable metals, unwanted elements or both.
FAQ
- Can Elmery treat tailings directly?
Elmery recovers metals from liquid streams. If metals are locked in solids, they first need to be dissolved through a suitable leaching route. - Is this wastewater treatment?
Elmery is a selective metal recovery and impurity removal step. It can support water and waste-stream management, but it is designed around selectivity of target metals, not generic water treatment. - Can recovery be economical at low concentrations?
Yes, depending on the metal, concentration, solution volume and existing treatment costs. Laboratory testing provides the recovery and selectivity data needed to evaluate the business case, which will then be confirmed in the pilot. - Can we test this without committing to a full installation?
Yes. The typical path starts with stream data and samples, then moves to lab validation and an on-site pilot. - What if the feed varies?
Expected variation is evaluated during laboratory and pilot work. Operating parameters are validated for an agreed composition range and can be retuned if the stream changes significantly.
