Danakali has published product specification sheets for major fertilizer ingredients, which has helped the company to market products from its Eritrean Colluli potash project. The project is located in the Danakil region of Eritrea, East Africa, and is fully owned by the Colluli Mining Share Company (CMSC). CMSC is a 50:50 Joint Venture between Danakali Limited and the Eritrean National Mining Company (ENAMCO). The company has specifically issued technical specifications and safety data for three products within the potash strain known as potassium sulphate or sulphate of potash (SOP).
Colluli’s SOP-Standard, SOP-Granular and SOP-Soluble products have each been labeled as high-purity in nature with no safety hazard statements attached. The reports praise the production earlier this year, especially 300 kilograms of product samples grading more than 98 percent SOP, or greater than 52 percent K2O equivalent. SOP provides both potassium and sulphur in soluble forms. It is a high-quality potash fertilizer carrying a price premium over the more common potassium chloride (MOP) as it contains no chloride and hence has a much lower salt index than MOP. In case of Danakali, SOP products have been made exclusively from potash salts extracted from Colluli. They demonstrate a favorable salt combination to produce high-purity SOP.
The publication of the specs will help discussions regarding sales deals with potential offtake parties as Danakali promotes its products around the world. This marketing effort is hoped to benefit both variability in product types as well as the technical specifications delivered in the most recent specs. The potassium bearing salts at Colluli have the exceptional capability of producing a variety of potash types including SOP, MOP and sulphate of potash magnesia (SOPM or potassium magnesium sulphate).
