Mining
 
The Mixaerator has proven itself as a valuable asset for the mining industry with outstanding results in a number of studies being undertaken at different locations by independent third parties.
 

  • Improves gold recovery process.
  • Eliminates the need for liquid oxygen.
  • Significantly improves cyanide reactant times.
  • Treats onsite wastewater

The Mixaerator technology has already produced outstanding results in acid mine water treatment.
 
CASE STUDY – A decommissioned tin mine, Australia
To comply with EPA requirements, the acid mine water at the tin mine required neutralization and the removal of heavy metals prior to release from the storage dam. The volume of silica/alumina based powdered material (red mud) required for heavy metal decontamination and pH adjustment made this process cost prohibitive.
 
A Mixaerator field unit was installed and the following results were determined by the NATA certified SCU Mineralogy Laboratory.

  • The Mixaerator mixed the additive material virtually instantaneously and achieved an outstanding reduction in reactant of 50% to just 10 grams per litre of red mud.
  • Effluent discharge quality significantly improved with the Mixaerator and mixing time was reduced by 75%.
  • The Mixaerator achieved a cost reduction of 85% based on the reduced volume of red mud required, plus the savings associated with halving the corresponding transport costs and application labour costs.
  • The Mixaerator eliminated the mine’s use of complex and labour intensive alternative treatments.

 

 Proven Results
The Mixaerator has proven itself as the most cost effective solution for Acid Mine Drainage and Acid Sulphate treatments using a product which is essentially the “red mud” byproduct material from alumina smelting operations.
 
The “red mud” is recognised worldwide as a resource/waste stream capable of neutralizing acid water and safely removing virtually all known metals contamination leaving water at a “pure drinking water” standard.
 
Tests conducted by Southern Cross University in Lismore prove that the Mixaerator technology dramatically improves the efficiency of this material and reduces application costs by nearly 80%.
