FROTH FLOTATION RECENT TRENDS IIME, JAMSHEDPUR, 1998 pp. 18-41 Flotation of Sulphide Ores - HZL Experience V.P. KOHAD Hindustan Zinc Ltd., Zawar Mines, Udaipur - 313 901 ABSTRACT Flotation process, patented in the year 1906, was originally developed for mineral industry to recover values from high grade tailings of gravity separation plants.
The flotation rate depends on the size of the spherolites, the flotation distance on the travel speed and the time available for flotation, and time in turn is a function of wall thickness. In thick-walled castings made of hypereutectic nodular graphite cast iron large spherolites are formed which have plenty of time for flotation due to the ...
Normally the flotation process is what is used to separate the graphite from the clay, if this is not happening you may need to adjust your reagents. Alternatively, if the clay is finely disseminated, classification will work after flotation. Do you have the quality specifications - physical e.g., sizing and chemical impurities, etc.

Graphite ore is mostly beneficiated using flotation separation techniques.
Multi-stage grinding amp multi-stage flotation. Xinhai usually applying multi-stage grinding process to protect graphite flake from damaged. Applying multiple grinding and separation to meet the customers needs. Hydrocyclone can be used at the thickening stage,which keep the grinding density at 40 to 50 for better grinding efficiency.
Overview of Graphite Flotation Process. Graphite Ore. Graphite ore is one of four forms of crystalline carbon the others are carbon nanotubes, diamonds, and fullerenes. Graphite occurs naturally in metamorphic rocks, such as gneiss, marble, and schist. It is a soft mineral also known by the names black lead, mineral carbon, and plumbago.
Graphite is a natural floater. Flotation has become the accepted method of beneficiation of graphite Crawford and Ralston, 2008. Flake graphite from disseminated deposits is difficult to concentrate, therefore, a number of processes have been evolved by different countries.

Graphite flotation must not be mistaken for kish graphite q. v. occurring in flake graphite cast iron. Flotation of graphite influences expansion and contraction of the cast iron during eutectic solidification and thus also interferes with seal feeding. Irregular distribution of the graphite results in inconsistent properties throughout the casting. The densiti difference between liquid iron and graphite is around
