BASF’s Rheomax® DR range of flocculants create a high density and more robust aggregate compared to conventional products, which are effective on a wide variety of mineral ore types.

This change in aggregate shape allows for faster consolidation, high underflow densities and low underflow yield stress.

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

The Rheomax® DR range of products produce an underflow with a lower yield stress, which is more tolerant to fluctuations in solids content and applied shear, resulting in a more consistent thickener performance over a wide range of operating parameters.

Benefits Delivered By Increased Throughput:

Economic

  • Reduced capital expenditure
  • Operate at higher feedwell solids

Operational

  • Tolerate greater feedwell fluctuations
  • Underflow solids compact faster

Benefits Delivered By Increased Underflow Density:

Economic

  • Improved recovery of leached metal
  • Improved recovery of concentrate

Operational

  • Increased CCD washing efficiency

Environmental

  • Improved recovery of water
  • Reduced volume of tails to residue
  • Reduced residue footprint
  • Reduced residue rehabilitation time

Benefits Delivered By Reduced Underflow Yield Stress:

Economic

  • Run at higher underflow densities
  • Improved leaching kinetics
  • Reduced energy consumption

Operational

  • Reduced rake torque
  • Improved thickener efficiency

BASF’s Magnafloc® range of flocculants and coagulants are used extensively whenever the extraction process uses water or lixiviants to aid mineral and metal recovery. 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.

Magnafloc® flocculants and coagulants have a broad applicability throughout the industry and are available in a wide variety of product forms, including powder, bead, solution and liquid dispersion.

BASF’s Zetag® Flocculant Technology – advanced dewatering performance For many years cationic polyacrylamide flocculants have been used in the sludge dewatering process. Optimizing the dewatered biosolids is essential to maintain the sustainability and efficiency of the process.

  • Optimized solid/liquid separation process
  • Excellent sludge dewatering results

BASF’s Burst®  A wide range of specialty surfactants used to assist in cleaning applications as wetting agents, anti-foams and emulsifier/dispersing agents.

BASF’s Antiprex®  A wide range of chelating agents,  organic acids, and anti-scalants.

BASF’s Magnasol® flocculants and coagulants can be supplied as liquids or in a solid block form and are ideally suited for remote locations where electricity is not available and hence can reduce or eliminate the use of flocculant and coagulant make-up equipment.

Innovative Solutions For Tailings Management

BASF’s RHEOMAX® ETD (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 is able to 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.

This treatment has been found to be effective in improving tailings properties from a wide cross-section of industries, including Alumina, Copper, Nickel, Gold, Iron Ore, Mineral Sands, Oil Sands and Copper.
