RE: US$1 billion of free cash flow per yearThe Department of Materials Science and Metallurgy at the University of Cambridge, U.K., sponsored by Amazon has invented a method for reacting verdete slate with a simple mixture of salts to form water-soluble potash. The reactions occur at moderate temperatures of 800 to 1,000 C, and most reagents are regenerated in process. The route allows for the production of potassium sulphate and muriate of potash.
The company's primary focus and immediate goal remains the development of its Cerrado Verde potash property and bringing its ThermoPotash fertilizer product into production. The company continues, in parallel, to develop a method for producing a conventional potash export commodity. The next step in the KCl and SOP product development process will be to initiate studies for a pilot plant. The current processing concept is simple and straightforward, and the company believes it can be scaled up to industrial levels.
