Aug 09, 2021Present flotation practice uses a reagent schedule which typically includes fatty acid or hydroxamic acid as a collector. In this research, it was found that better bastnaesite flotation is achieved at a low level of lauryl phosphate addition when compared to the use of octyl hydroxamate as a collector.

Selective flotation of Mount Weld phosphate ore

Oct 30, 2021This report describes the use of flotation as a method of upgrading Mt Weld phosphate ore. The QEM SEM technique was used to help understand the flotation behaviour of the various minerals, particles and composite particles in the ore. A key feature of the flotation was the use of sodium silicate as a selective depressant for the iron oxides.

Flotation separation of strontium via phosphate

Mar 02, 2021Flotation separation of strontium (Sr) from wastewater via phosphate precipitation was investigated. While 37.33% of Sr precipitated at highly alkaline pH in the absence of PO 4 3−, it completely precipitated as Sr 3 (PO 4) 2 at a molar ratio ([PO 4 3−]:[Sr 2+]) of 0.62 at a lower pH value.The presence of Ca 2+ hindered Sr precipitation, yet it could be overcome by increasing the PO

Evaluation of the Influence of Process Variables on

Froth flotation is an adsorptive-bubble separation method based on the selective attachment of particles on the surfaces of gas bubbles passing through a suspension. Reagents as collectors, frothers and pH modifiers are added to perform specific roles to facilitate and to improve the separation. In the present work the process of apatite flotation in column has been investigated experimentally.

Abstract Flotation has been used in industry for more than a half century as the primary technique for upgrading phosphate. While the flotation of phosphate was inefficient when oleic acid was used alone as a collector, therefore a mixed collector of oleic acid (HOl), linoleic acid (LA) and linolenic acid (LNA) was employed to improve the recovery of phosphate flotation.
