Our ADR Systems promise sustainability and productivity

To get the most out of your processing plant, it is essential to have a system that maximises gold and silver recovery as efficiently as possible.

We believe it’s our responsibility to produce equipment that is both sustainable and productive, and for this reason, we proudly offer our range of ADR equipment and systems. We have engineered our ADR technology to be light on power usage without sacrificing time or recovery. 


Through FLSmidth systems, we offer the complete silver and gold recovery flowsheet including materials handling, crushing, milling, leaching, adsorption, recovery, and refining to produce gold and silver doré.


Our equipment and systems are robust and require little maintenance. As most mine sites are not located near urban areas, we design and build for longevity and trouble-free service. Our design and development teams benefit from years of in-house and field testing, and our products have been created and are continually updated to provide longstanding performance in the most demanding conditions presented in the mining industry.


We stand behind our quality products. All components, equipment and systems are covered under the FLSmidth one point of source sales warranty, eliminating the need to get warranty help from individual component suppliers.

Our equipment and systems are available with many options, making our products versatile and easier to tailor to your specific needs. Depending on your project location we can utilise our global supply chain to optimise equipment sourcing and fabrication locations to best suit your project needs and ensure we can support your operation over the entire mine life.
