K-Max® Technology – for processing micaceous minerals
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.
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.
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.
Parkway Minerals has performed a range of studies on the potential of constructing a K-Max® plant. 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.
