2003-10-22were tested as flotation depressants of galena and chalcocite in a Hallimond cell with xanthate to make the sulfides hydrophobic. All dextrins, except prepared under hydrogen sulfide, depressed flotation of the sulfides. The cessation of flotation occurred at different doses of dextrins, usually between 2 and 20 kg per ton of the floated material.

2011-12-14The flotation cell is a modified Hallimond tube5 sufficient to hold 100 c.c. with a glass frit bottom for gas entrance. Controlled agita- species has no effect on the flotation of scheelite. A similar effect is obtained by the use of Ca NO3 2 which shows excellent flotability of scheelite in a wide pH range. In contrast to.

2011-2-24Coulometer. Flotation experiments were conducted with a 300-ml modified Hallimond tube with a 4-g sample of 147 x 300 m fluorite. In all experiments a minimum ionic strength of 0.01 M was established with KNO3, but overridden at high additions of Ca2. Contact angles were measured with air bubbles on polished specimens inverted in an optical.
