Tunisia is worldwide pioneer in the domain of natural phosphate and mineral derivatives. This activity of phosphate extraction and enrichment has been for more than a century. The natural phosphate of Tunisia mining bassin is of sedimentary type: a francolite (fluoroapatite carbonate) coming from deposits on marine bottom, generally formed in shallow coasty areas. The research studies conducted on TUNISIA phosphate, by the International Fertilizer Development Center (IFDC, Alabama, United States of America), were crowned by two certificates delivered by the IFDC. These documents certify that the natural TUNISIA phosphate is highly reactive and can be recommended as an efficient fertilizer for direct application. These evaluations support the results found by distinguished scientists throughout the world. To obtain a final product meeting client&＃39;s requirements, TUNISIA handles no effort to ensure the reliability of its phosphate quality.
