Flotation of Smithsonite From Quartz Using Pyrophyllite ...

2021-1-1  PNPs showed good selectivity for the smithsonite/quartz flotation system. For mixed minerals, zinc concentrates with a zinc grade of 50.84% and a zinc recovery of 85.36% can be obtained using PNPs as a collector at pH 6. The flotation performance of PNPs is better than that of the NaOL or DDA collector for this mineral system.

The role of hydrolysis in sulfonate flotation of quartz

2021-1-9  quartz. As revealed in Fig. 1, no flotation could be effected at pH 2.19 at a constant sulfonate concen­ tration of 5.52 x 10-5 mole per liter and constant Fe+++ concentration of 1.83 x 10-4 mole per liter. A slight increase in flotation pH (i.e. 2.27) resulted in a recovery of 73 pet, while complete flotation was effected at pH 2.42.
