Water Treatment & Solid / Liquid Separation

Quadra offers a range of range of flocculants and coagulants which are used extensively whenever the extraction process uses water or lixiviants to aid mineral and metal recovery.

Coagulants & Flocculants are to improve the rate of solid / liquid separation in an aqueous slurry i.e. to destabilise the slurry so that the solids settle or can be filtered more easily. Bringing together small particles or aggregates into much larger aggregations using long chain molecules which bridge between particles and bind them into a macro-structure (floc).


Flocculants increase the rate at which water can be separated from solids.


Aggregation of the solids through flocculation leads to increased permeability of the solids fraction in relation to the water phase.

Sedimentation – increase settlement rate

Filtration – increase rate of water release

Applications: clarification, centrifuges, thickeners, organic binders, filter presses, drilling mud, run off streams, geo bags, vacuum drum, tailings, tailings dust suppressant, mineral recovery, arsenic treatment.

Quadra exclusively represents the BASF portfolio of mining solutions products in Canada and Alaska. BASF’s Mining Solutions business offers a diverse range of mineral processing chemicals and technologies to improve process efficiencies and support the economic extraction of valuable resources.

Magnafloc®: Standard anionic, non-ionic & cationic flocculants:

In thickeners and clarifiers, the products are designed to enhance settling rates, improve clarities and reduce underflow volumes. When used in filtration processes, Magnafloc® reagents increase filtration rates and yields, as well as reducing cake moisture contents.


Rheomax® DR  High performance flocculant:

Our advanced the range of flocculants create a high density and more robust aggregate compared to conventional products, which are effective on a wide variety of mineral one types. This change in aggregate shape allows for faster consolidation, high underflow densities and low underflow yield stress.

Rheomax® DR advanced flocculants have demonstrated benefits to solid / liquid separation processes by enabling improvements to be made to thickener throughout, underflow density and yield stress.

Rheomax® ETD Tailings Management:

Enhanced Tailings Disposal is a method of Tailings Management in which novel technology is used to change and control the structural and drainage properties of mineral processing residues. Tailings thickeners generate high-density underflows with high yield stress, which are often pumped long distances to a final tailings impoundment area. The tailings are then deposited, dried and eventually rehabilitated.

The Rheomax® ETD process can rigidify tailings at the point of disposal by initiating instantaneous water release from the treated slurry. This accelerates the drying time of the tailings, results in a smaller tailings footprint and allows the released water to be returned to the process faster.

LIX® Solvent Extraction  

At the core of BASF’s offering is an extensive range of LIX oxime extractants and amine extractants that are widely used in the purification of copper, uranium, nickel, vanadium, molybdenum, germanium, palladium, rare earths and other precious metals from leach solutions.

LIX solvent extractants are recognized throughout the copper industry as the go to reagent for copper recovery. BASF’s broad range includes aldoxime and ketoxime extractants and incorporates blends formulated to specific customer needs / operational challenges. Our range of solvent extraction reagents are produced at our state of art facility in Cork, Ireland. These water insoluble oximes, in a high flash point hydrocarbon diluent, form water insoluble complexes with various metallic cations.
