Potash West is working on its revolutionary glauconite-to-fertiliser Dandaragan Trough project located to the north of Perth in Western Australia. It is focussed on developing the extensive greensand beds at Dandaragan Trough where it has 2,900 km2 of exploration tenure, in an area of high quality infrastructure. The project is also located adjacent to the Western Australian Wheat Belt, a major consumer of fertiliser products.
The company reports that as a result of a significant amount of test work and investigations carried out by the company and its partners, a flowsheet has been developed that produces sulphate of potash (SOP), high magnesium SOP, single superphosphate, iron oxide and aluminium sulphate, from glauconite that is extracted from the extensive greensand deposits in the Dandaragan Trough. This has been called the K-Max process and will become a valuable asset of Potash West.
To maximise the value of this intellectual property, Potash West has applied for a patent. It has developed considerable knowledge in the processing of the greensand, with ongoing investigations continuing to enhance the value of this resource, and the application of the K-Max process to other deposits. Potash West has already been approached by other companies seeking information on this processing breakthrough.
