Chat Online1. Introduction. Pyrophyllite is a hydrous layered aluminum silicate Al 2 Si 4 O 10 (OH) 2 with a kind of 2 1 structure consists of individual sheets of Al(O OH) 6 octahedra sandwiched between sheets of SiO 4 tetrahedra. The pyrophyllite is theoretically composed of 67 SiO 2 28 Al 2 O 3 and 5 H 2 O in which Al is likely to be replaced by Fe or some like Mg Ca Na or K .

Chat OnlineThe above flotation results may be correlated with the galvanic current data for the two- and three-electrode systems as presented in Table 1. From this correlation it is apparent that the higher the rate of the cathodic reaction at a mineral surface the stronger the adverse effect on its flotation recovery.
Chat OnlineThere 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 .
