Evaluation of Estonian phosphate rock by flotation

Estonia holds the largest unexploited sedimentary phosphate rock reserves in the EU. Compared to other sedimentary and also igneous phosphate rocks the Estonian phosphorite is particularly outstanding by its remarkably low Cd (1–5 ppm) and trace U content (~50 ppm) and also contains valuable elements such as rare earth elements (REEs), which could be used in important high-technologies in

Effect of Flotation Time and Collector Dosage on Estonian

Reverse flotation was found to be the most efficient processes to upgrade the phosphate level in Estonian phosphorite which is applied in this study. Phosphate concentration that is needed in wet process should contain more than 30% P 2 O 5,less than 1% MgO, and 1.6 CaO/P 2 O 5 ratio and between 2–3% of Al 2 O 3 and Fe 2 O 3 [ 3 ].

Phosphorus is an essential and non-substitutable element for the cellular processes of all living organisms. The main source of phosphorus in the biosphere is phosphate rock. With more than 700 Mt phosphate rock, Estonia holds the largest sedimentary phosphate rock deposits in the European Union. Estonian phosphate rock is particularly outstanding due to its remarkably low content of hazardous
