Finnfix® and Celect®
CMC depressantsMining solutions for
improved performance

CMCCMCUnique advantages forthe mining industry
Not all carboxymethyl cellulose (CMC) is created equal. Our Finnfix®
and Celect® CMC mining solutions are designed to enhance thedepressant function improving the recovery and grade of valuable
mineral while reducing costs and reagent consumption.

We collaborate with you to understand therequirements of each mine, combining ourexpertise in metallurgical testing with a robust
product portfolio to deliver solutions that will
improve flotation efficiency.

Nickel recovery %In laboratory tests, the use of Finnfix® and Celect®
CMC was shown to decrease depressantconsumption by more than 50%, reducereagent cost by up to 20% and increase valuable
metal recovery by at least 10% for minesaround the world. In full-scale plant operations,
our CMC reagents have also been proven to
significantly lower the amount of depressantconsumed when compared to alternatives.

Investing in flotation innovations

Throughout the lifecycle of a mine, the changing
characteristics of ores requires cyclicalrefinement of mineral processing systems.
We collaborate closely with our customers
so we can routinely optimize and refine
depressants to ensure our CMC products
continue to deliver significant value by reducing
dosage and cost and improving performance
during flotation.

With more than 50 years of flotation application
research and development, we have built an
extensive understanding of the fundamental
chemistry and adsorption mechanisms
involved in selective flotation. Based on thedata obtained in our metallurgical testinglaboratory, we identify the best solutions foryour application.

Starting at the molecular level, we use
modeling to test and prove which factors
affect depression efficiency and selectivity.
High-confidence testing is performed by ourscientists and metallurgists to ensure datareliability and quantify the value associatedwith recovery and reagent efficiency while
minimizing trial risks. You can rely on theconsistent quality of our responsibly sourced,
bio-based Finnfix® and Celect® CMC producedin Finland – the largest CMC production plantin the world.
