The Effect Of Grinding On Pyrophyllite Flotation

The formation of zeolite Na-X and Na-A was depended on the degree of activation caused by grinding; i.e., grinding accelerated the dissolution of loosely bonded Si substances rather than Al ones of the ground pyrophyllite particles leading the Si/Al molar ratio close to 1.2, which is favorable for the formation of zeolite Na-X.

Effect of microwave pretreatment on grinding and flotation ...

The present work initially studies the kinetics of microwave-assisted grinding and flotation in a porphyry copper deposit. The kinetics tests were carried out on the untreated and microwave irradiated samples by varying the exposure time from 15-150 sec. Optical microscopy, energy-dispersive X-ray spectroscopy and scanning electron microscopy were used for determining the mineral liberation ...

EFFECTS OF DRY GRINDING ON PYROPHYLLITE

Hayashi et al. (1962) studied the continued grinding of pyrophyllite and its effect on toxicity of the cell. Juh/tsz (1977) suggested that destruction of this mineral during mechanochemical activation (intensive dry grinding) may be accelerated by cations and adsorbed water. Pyrophyllite solid solutions have been synthesized by Rosenberg ...

How Particle Size Affects Flotation

There is a marked particle size effect on both R and K. Table V gives an example of increasingly finer grinds in flotation with a different sulfide ore blend. Within the times of grind indicated, there is a tendency for both the over-all R and K values to increase with finer grind [see also Table III of reference]. This trend continues until sufficient fine material is produced (e.g., note the ...
