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 ].

Effect of Flotation Time and Collector Dosage on Estonian

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

Flotation Mineral Processing & Metallurgy

Jan 11, 2016 Metallurgical Content The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores.

Froth flotation

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
