A study of flotation characteristics of monazite,

2017-1-10  The floatability of monazite was generally higher than that of hematite. The flotation recovery of quartz is dependent on the collector type used. Quartz flotation was not achieved with sodium oleate. Under conditions where flotation of quartz was observed, the floatability was poor in comparison to monazite and hematite.

Mechanisms of Dodecylamine Flotation of Quartz:

2018-6-13  Primary monoamines have been long used and studied as flotation collectors for quartz. In the past several mechanisms have been proposed to explain the manner in which the amines adsorb onto and render the mineral hydrophobic and, thus, floatable.

Flotation Of Quartz And Hematite: Adsorption

It was observed that hematite flotation recovery is maximum at acidic pH with sodium dodecyl sulphate (SDS), neutral pH with oleate, and at basic pH about 9.5 with C12 amine. Flotation results with both quartz and hematite indicate an increased adsorption of cationic collector in the presence of anionic collector apart from its own co-adsorption.

Evaluation of hematite and quartz flotation kinetics

The flotation results showed that the biosurfactant produced by Rhodococcus erythropolis had more selectivity for hematite than quartz and can act as a collector reagent for hematite. The maximum floatability values of hematite and quartz were 99.98% and 17.53%, respectively.

Selective Separation of Hematite from Quartz by

This study investigates the dual function of a temperature responsive anionic co-polymer of poly (N-isopropyl acrylamide) (PNIPAM) as a selective flocculant/flotation collector. PNIPAM is used for separating hematite from 50:50 mixtures of hematite and quartz, at a variety of particle sizes. The performance of PNIPAM in this system is compared to that of conventional flotation collectors ...
