Agglomeration Skin Flotation of Coarse Phosphate Rock

Flotation was introduced in phosphate rock processing in the late twenties and since then it has been an important part of the concentration process. More than two thirds of the rock produced in Florida is upgraded by the flotation process. Since no crushing or milling steps are involved in the material preparation, the flotation plant feed is coarser than in most other mineral flotation systems.

Yes, that's the process. Is it considered as a form of beneficiation? Andy Dingley 09:31, 22 July 2015 (UTC) I've no expertise here, but beneficiation involves physical separation of ore from gangue - whereas roasting involves a chemical change of the ore mineral to an oxide or other form more easily processed to a metallic form.

Fine Particle Beneficiation through Selective ...

A high internal phase (HIP) water-in-oil emulsion was used as the binder in the selective agglomeration of fine coal from an aqueous suspension of coal and mineral particles. Traditionally, this agglomeration is achieved by a pure oil, hydrophobic, binder. However, the high cost associated with using pure oil makes the process economically unfeasible.

The most recent agglomeration process, a second immiscible phase is added to the Suspension. This wets the solid phase and binds the particles together by means of capillary forces. As a results, rounded flocs or agglomerates form with diameters up to 5 mm. Selective agglomeration can be achieved for mixtures of solids.

Mineral processing - Wikipedia

Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles.
