US6889844B1 - Collectorless flotation - Google Patents

The present invention relates to a process for improving the recovery of valuable sulphide minerals. The process involves determining an Eh range within which the valuable sulphide mineral may be recovered by flotation without the need of a collector. The slurry is then subjected to flotation in a pneumatic cell 50 at such a speed that the slurry remains within the Eh range during flotation.

Effect of different reagent regime on the kinetic

Gilsonite is a natural fossil resource, similar to an oil asphalt high in asphaltenes. To determine the effect of reagent regime on the kinetic order and rate of flotation for a gilsonite sample, experiments were carried out in both rougher and cleaner flotation process.

Microwave Assisted Liberation of High Phosphorus

2014-9-26The influence of microwave treatment on the liberation of iron ore from the high phosphorus oolitic iron ore from Aswan region, Egypt was studied. The effect of microwave power, exposure time and grain size on the liberation of iron ore was investigated. The microfractures and cracks of the samples were characterized before and after microwave treatments.

Oxidation of Synthetic and Natural Samples of

2019-5-26The surface oxidation of synthetic and natural samples of enargite and tennantite has been monitored by X-ray photoelectron spectroscopy, XPS. The minerals were conditioned at pH 11.0 in an aqueous solution purged with nitrogen gas for 20 min or with oxygen gas for 60 min. The XPS results show that the oxidation layer on the mineral surface is thin. The surface oxidation products comprise ...
