Mercury Recovery Technology for Small Scale Mining

What governments, funders, and operators should look for when evaluating mercury recovery technology for small scale mining.

Quick answer: Mercury recovery technology for small scale mining has to work in difficult field conditions. The best systems are portable, verifiable, safe for workers, realistic for local operators, and connected to a plan for tailings, water, and long-term site management.

The technology problem is not only technical

Artisanal and small scale gold mining sites are often remote, under-capitalized, and lightly regulated. A technology that works in a controlled demonstration may fail if it needs constant specialized maintenance, expensive consumables, or a power supply the site does not have.

That is why mercury recovery technology should be evaluated as an operating system, not only as a machine. The question is whether the system can be deployed, maintained, measured, and trusted in the field.

What recovery technology needs to do

A credible system should reduce mercury exposure during processing, capture recoverable mercury from contaminated material, and prevent contaminated tailings from moving into soil and water.

For active mining areas, this can include safer handling, controlled processing, retorts, closed capture, training, and better separation practices. For legacy tailings, it may include screening, concentration, recovery, stabilization, and water controls.

Verification matters

Technology claims are only useful when they can be measured. Funders should ask for baseline data, post-treatment data, chain of custody for recovered material, and third-party lab verification where possible.

The strongest projects also track adoption. If miners do not use the system after the demonstration team leaves, mercury reduction will not last.

Why water belongs in the same platform

Mercury recovery work often happens near streams, shallow wells, floodplains, or informal settlement areas. If water movement is not controlled, a project can disturb contaminated material and increase exposure.

Water security should be part of the project design. That includes drainage control, source protection, potable water planning, and ongoing monitoring.

Questions before funding

Before funding a mercury recovery technology, ask:

What forms of mercury can the system address?
What site conditions limit performance?
How is recovery measured?
What happens to recovered mercury?
Who maintains the system locally?
How are water pathways protected?
What is the plan for tailings after recovery?

A platform view

Global Mercury Recovery & Water Security is positioned around this broader operating view. Recovery technology is important, but the durable value comes from connecting recovery to water infrastructure, tailings transformation, land regeneration, and grant-ready documentation.
