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.
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.
2014-8-25based processes to remove non-combustible minerals and to lower the concentration of pollutants such as sulfur. This paper summarizes the washability study conducted under the coal quality evaluation and beneficiation project of Azad Kashmir Pakistan coalfield. The aim of the study was to investigate and interpret
Abstract. The physical and chemical forms of sulfide mineral surfaces are reviewed. The initial surfaces and oxidation products have been studied by Scanning Auger Microscopy SAM, X-ray Photoelectron Spectroscopy XPS, Scanning Tunneling Microscopy STM, Atomic Force Microscopy AFM, Scanning Electron Microscopy SEM and Time-of-Flight Secondary Ion Mass Spectrometry ToF-SIMS.

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.
Rapid estimation of floatability components in industrial flotation plants Rapid estimation of floatability components in industrial flotation plants Alexander, D.J. Morrison, R.D. 1998-02-01 000000 In the analysis of industrial flotation plant data, it is advantageous to build a reliable computer based flotation model to be used in optimisation and design.
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 ...

This discoloration is the result of oxidation and is caused primarily by two things contact with sulfur compounds, and moisture. Technically hydrogen sulfide causes the reaction, and its found in lots of everyday objects like wool, rubber, and foods like eggs and onions. ... you should avoid cleaning the non-metal pieces with silver-specific ...
