Mining and mineral processing

High-performance coagulants & flocculants for mine water and mineral processing

Our OptiFlox® range of coagulants and flocculants is specifically designed for a wide variety of applications relating to mining and mineral processing. This range is available in both powder and liquid form and in a variety of molecular weights and charge densities tailored for the following applications:

  • Clarification of mine water for re-use
  • Clarification of surface water runoff
  • Solid liquid separation in for tailngs thickeners and process thickeners
  • Sludge or slurry dewatering via filtration or centrifugation
  • Ore washing and flotation

OptiFlox® system – An exciting new story

We have developed the OptiFlox® system, a new patent-pending technology and chemistry that has applications for:
  • Minimising losses in productivity and revenue via enhancing tailings thickener performance to produce consistent and reliable clarified water for return to the plant
  • Improving the recovery of valuable mineral resources

Application for coal mining

Shut down of tailings thickeners

It is well known that from time to time mines are confronted with the issue of very turbid water flowing from their tailings thickener. The clarity of this water from the thickener can deteriorate to an unacceptable level, resulting in the wash plant shutting down and production ceasing. Substantial losses in productivity and revenue can result.

Product Losses from Coal Thickeners

At times, coal mines are also challenged with the issue of product losses flowing from coal fines thickeners. Sometimes referred to as “rafting”, less than optimal surface charge conditions prevent coal fines from being totally captured, and valuable product is lost.

OptiFlox® is a proprietary system that addresses these operational issues. It is a new technology that continuously measures the particle characteristics of coal slurry in order to maintain optimal flocculation conditions through automatic, real-time control of coagulant dosing. A provisional patent application has been filed in Australia relating to the technology.
