Apatite And Calcite Separation By Flotation

The separation of limonite from calcite by flotation is a problem to be solved, and it was investigated systematically in this paper. Flotation tests show that the recoveries of limonite and calcite are close to 95% within the pH range of – using 3 × 10 −4 mol/L sodium oleate as collector. However, the flotation of limonite was ...

Improved Flotation Separation of Apatite from Calcite with. Apatite (Ca 10 (PO 4) 6 F 2) is the most important phosphate mineral, and flotation is the main beneficiation method to separate apatite from its major gangue mineral calcite (CaCO 3). Cited by: 3 Improved Flotation Separation of Apatite from Calcite with . Apatite (Ca10(PO4)6F2) is the most important phosphate mineral, and flotation ...

The flotation separation of salt type calcium minerals is problematic, due to the similarities in their same active Ca 2+ related site for interaction with anionic collectors and similar physicochemical characteristics such as solubility, zeropoint charge, surface speciation and Casite density. The work was performed to achieve effective and selective separation of the calciumminerals using ...

Flotation has been the most widely adopted technique for the separation of dolomite from apatite for this kind of magnesium (calcium) phosphate ore, and an anionic collector, such as sodium oleate, is usually used in the acidic pulp for reverse flotation [1–3]. Flotation is a separation method based on the di erence of physical and chemical properties between valuable minerals and gangue ...

Predictions for flotation separation based on single mineral tests often fail in these systems mainly owing to the interactions between dissolved mineral species. The effect of dissolved mineral species of the calciteapatite system is investigated in this study using the electrokinetic technique. The electrochemical, dissolution and spectroscopic properties of each mineral were markedly ...

Abstract. The flotation process currently considered for apatite concentration from the Santa Quitéria phosphate deposit (Brazil), involves bulk flotation of apatite and calcite with anionic collector at pH=10 followed by calcite flotation at pH=, adjusted with H 3 PO this concept is efficient from the point of view of separation between apatite and calcite, the intensive use of ...

Abstract The separation between calcium minerals such as apatite and calcite by flotation relies on the use of long chain fatty acid collectors. Oleic acid, and its salt, is the main fatty acid collector and many studies have reported on the mechanisms of its interaction with calcium at the mineral surface and in solution, and on the oleic acid species present at the mineral surface.

 · ABSTRACT. Apatite (Ca 10 (PO 4) 6 F 2) is the most important phosphate mineral, and flotation is the main beneficiation method to separate apatite from its major gangue mineral calcite (CaCO 3).Till date, fatty acids and their salts have been widely used as collectors in the apatite/calcite flotation separation due to their low cost and strong collecting ability, but their selectivity is limited.
