Parkway Minerals owns a portfolio of highly innovative brine and mineral processing technologies with the potential to significantly improve the efficiency, performance and sustainability of a range of industrial operations, particularly in conventional brine and minerals processing related applications. 

 

Whilst these exciting technologies have applications in a range of sectors, Parkway Minerals is concentrating initial efforts onproviding long-term sustainable solutions for processing complex brines, in the energy, mining and wastewater industries.

In order to protect the valuable intellectual property (IP) portfolio, Parkway Minerals has developed a Multilayered IP Protection Strategy. The IP portfolio consists of i) Trade Secrets, ii) Know-how, iii) Trademarks and iv) Patents.

aMES™ Technology

The activated Minerals Extraction System, or aMES™ is an innovative process technology that enables the treatment of concentrated brine solutions to recover a range of valuable minerals, reagents and fresh water. The technology utilises a proprietary multi-staged process incorporating novel membrane technology and is based on proprietary IP, incorporating patents, expertise and know-how acquired over more than a decade of intense process development initiatives.

 

Advantages:

  • Improvements in mineral recovery and product quality.

  • Opportunity for substantial project capex & opex savings.

  • Highly efficient use of energy and produces water as by-product. 

  • Reduced water consumption.

  • Improved project footprint and environmental sustainability.

Key Industries (Applications)

  • Mining natural brine (salt lakes)

  • Solution mining brine (potash)

  • Refinery & industrial waste brine

  • Water treatment waste brine

Target Products (Produced)

  • Potash (MOP/SOP/KMS) 

  • Lithium and magnesium salts

  • Range of byproducts (B, Br, Co, Na, Ni, NH4, Si)

  • Reagents 

  • Water

iBC™ Technology

 

The integrated Brine Causticization, or iBC™ is a patented process technology that simultaneously removes common impurities from waste brine streams and converts sodium carbonates and bicarbonates commonly found in coal seam gas (CSG) brines, into more soluble sodium hydroxide. As a result of the causticization step, the iBC™ technology produces a purified brine suitable for downstream processing, including with the aMES™ technology, for the production of various salt products and industrial-grade sodium hydroxide.

 

 

Key Industries (Applications)

  • Industrial waste brine (CSG)

  • Water treatment waste brine

Target Products (Produced)

  • Sodium hydroxide concentrate

  • Sodium chloride 

  • Byproducts (Ca, Mg, Si)

Next Steps

  • Parkway has been approached by several CSG industry participants, including operators, to explore options, as conventional approaches are inadequate.

  • As part of the acquisition of the iBC technology, a pilot plant will be relocated to Victoria University, where a detailed technology optimisation and integration program will be undertaken to support ongoing business development activities in the CSG industry and assist in the commercialisation of the technology.

K-Max® Technology

The K-Max® technology was developed by Parkway Minerals in order to process glauconite and a range of micaceous minerals. A scoping study prepared by Parkway Minerals demonstrated the potential feasibility of producing several valuable products, including sulphate of potash.

 

Advantages:

  • Efficient hydrometallurgical process with numerous potential applications.

  • Allows the production of a range of products from unconventional minerals, mainly micaceous minerals.

  • Potential to utilise the technology to produce potassium sulphate (SOP), potassium magnesium sulphate (KMS), phosphoric acid, iron oxide and aluminum sulphate.
