Flotation Reagents for Mineral Processing

Mining operators depend on Syensqo's AERO® and AEROFLOAT® copper flotation reagents to improve the recovery of copper from ores such as copper-nickel, copper-molybdenum and oxide copper. Syensqo also offers Transfoamer™ frothers specifically tailored to the needs of copper coarse particle recovery.  

Syensqo's versatile gold flotation reagents - such as AERO®, AEROFLOAT®, MAXGOLD® and OREPREP® - help meet the recovery challenges associated with gold-bearing ores, such as variable mineralogy, particle size and the presence of gangue.

To meet growing lithium demand for applications such as batteries, Syensqo's AERO® flotation collectors facilitate lithium recovery from hard-rock sources such as spodumene. Learn more about our lithium offer.

Syensqo's reagents are commonly employed in copper-molybdenum separations. Our AERO® reagents contribute to improved and more consistent molybdenum recovery. AERO® depressants can be used as a substitute or supplement for NaSH when separating copper from molybdenum.

Syensqo's OREPREP® and AERO® reagents facilitate nickel and cobalt recovery, and they offer improved sustainability profiles versus competing chemistries such as xanthates.

Syensqo offers a range of phosphine flotation chemistry to support activities in the phosphate value chain, including ACCO-PHOS® heavy metal removal agents, OREPREP® frothers and AERO® collectors.

Syensqo's AEROFLOAT® and AEROPHINE® reagents optimize the recovery of platinum group metals, enabling high recovery rates, especially when used in combination with other reagent chemistries.  

As challenges persist in selectively recovering value metals from polymetallic ores, polymetallic flotation reagents such as AEROFLOAT® and OREPREP® are ideal for the flotation of silver, copper, lead and zinc. 

Silver tends to concentrate with copper and lead sulfides. AEROFLOAT® and AEROPHINE® silver flotation reagents are widely used to optimize silver recovery from concentrates.
