This paper reviews the applications of time of flight secondary ion mass spectrometry (TOF-
SIMS) used for surface chemical analysis of mineral in the context of froth flotation. A wide …

The history of development of Process Mineralogy is reviewed, and updated. Specifically,
the approach taken by Xstrata Process Support is discussed. It is shown that across the …

With the increased exposure to progressively complex ores, there is growing concern over
the effects of phyllosilicate gangue minerals. These minerals present challenges during ore …

The paper presents the outcomes of exploratory research relating to the atmospheric
pressure and ambient temperature leaching of nickel and cobalt from a Western Australian …

The effect of various calcium ionic concentration on the adsorption of carboxymethyl
cellulose (CMC) onto talc surface has been investigated using flotation tests, adsorption …

Zinc sulfate is a commonly used selective depressant for zinc sulfide minerals, and a mixture
of ZnSO 4 and Na 2 CO 3 is an effective combined inhibitor for talc. This study indicated that …

During the recovery of the valuable platinum group minerals and base metal sulphides in
the Merensky Reef ore by flotation, a certain amount of naturally floatable gangue (NFG) is …

The extraction of nickel (Ni) from sulfide resources commences with flotation to produce a
concentrate which is then smelted to produce a nickel-enriched phase called matte, and …

In spite of numerous studies on PGM behaviour in flotation, there remains much discrepancy
regarding PGM speciation and its impact on floatability, as PGMs are routinely considered …

For processing low grade complex ores there is a need to improve operation efficiency to
maintain profitability. This may be done by introducing more efficient equipment or improving …
