Flotation of graphite - ScienceDirect

Jan 01, 1991  In graphite flotation, a variety of nonpolar oils such as kerosene and fuel oil are generally used in combination with frothers such as pine oil or higher alcohol. In many respects, graphite responds to flotation in a similar way to coal or molybdenite. The pH of the pulp is usually adjusted to about pH 8.

Graphite flotation - GIESSEREILEXIKON.COM

Graphite flotation. Graphite diffusing from cast iron melts rising to the top of the melt. In metallographic specimen floating graphite is very clearly identifiable even with low degree of magnification. At broken or machined surfaces, the diffused and floated spherolites can be identified as dark spots even with the unaided eye ( Figures 1 to 3 ).

A Possible Mechanism for the Formation of Exploded ...

In hypereutectic nodular cast irons, primary precipitation of graphite may lead to graphite flotation in thick section castings. Graphite degeneracy such as so-called exploded graphite is then often associated with this flotation phenomenon and it appears as precipitates where the nodular form is replaced by star-like or flower-like shape. It has been reported that exploded graphite develops ...

Molybdenum - Wikipedia

Molybdenum is a chemical element with the symbol Mo and atomic number 42. The name is from Neo-Latin molybdaenum, which is based on Ancient Greek Μόλυβδος molybdos, meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new entity from the mineral salts of ...
