K-Max® Technology

K-Max® Technology – for processing micaceous minerals

The K-Max® technology was developed by Parkway Minerals in order to process glauconite (such as can be found at the Dandaragan Trough Project) 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.

What is K-Max®?

  • A patented hydrometallurgical process with applications in extracting potassium and other elements to make a range of products.

  • The process utilises hot sulphuric acid to leach a range of amenable feedstocks.

  • In addition to processing glauconite, the process is also applicable to other mica-like minerals, such as phlogopite.

 

 

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. 

 

 

Technology Application

Parkway Minerals has performed a range of studies on the potential of constructing a K-Max® plant for the Dandaragan Trough Project. The primary flowsheet involves the leaching of recovered glauconite with sulphuric acid and the subsequent processing in order to produce a sulphate of potash (SOP) and potassium magnesium sulphate (KMS) product.
