Developing capabilities in gold and silver recovery

At FLSmidth, we can claim that we have the most complete flowsheets of gold and silver extraction in the industry. The FLSmidth Minerals Research and Development group focuses its efforts on improving existing process and unit operations technologies, as well as developing ideas and proving concepts that will take your operation into new technological areas.

Through our close work with the Gold Technology Group at Curtin University via the AMIRA P420 Project, we are working to create numerous innovative solutions to issues often faced by miners, and to find ways to optimise processes and equipment.

We are having successes such as our global award-winning Top 100 R&D Rapid Oxidative Leach (ROL) processing technology.


Greater yield with energy efficient products

It is our responsibility to bring you equipment that is sustainable and has low environmental impact.


For gravity recoverable gold, our gravity separation equipment has the highest throughput technology on the market and is able to process at a higher solids ratio than our competitors.


For carbon ADR, our patented split-strip process will maximise your carbon throughput while minimizing energy input, equipment size and quantity, and layout footprint.


We promise greater yield with smaller impact.


Our customer service promise

With our Total Life Cycle support program, we aim to assist you through installation assistance, commissioning advice, troubleshooting, optimisation or general consulting services. No matter where you are located in the world, we will be here for you.
