The potassium bearing salts within the Colluli Resource have the unique capability of producing a diverse range of potash types including sulphate of potash (SOP or potassium sulphate), muriate of potash (MOP or potassium chloride) and sulphate of potash magnesia (SOPM or potassium magnesium sulphate).
Substantial upside for the project exists from the exploitation of other contained products within the resource such as high purity rock salt and magnesium chloride and other identified minerals within the project license such as gypsum (Calcium Sulphate).
The product, detailed below, have been generated exclusively from potash salts extracted from the Colluli Resource in Eritrea, East Africa and demonstrates Colluli’s favourable salt combination to simply and economically produce high purity SOP.
Approximately 4 tonnes of Colluli drill core material have been processed at the Saskatchewan Research Council (SRC) in Canada for specific bench testing and pilot plant trials to produce SOP, which was delivered in soluble, standard and granular forms. Over 100kg of Colluli product was tested at Ludman Industries in the USA for product compaction behaviour. Materials handling trials have also been completed to determine the anti-caking requirements for the final SOP product. These repeated tests have produced the following product type specifications:
