Quartz is the dominant gangue mineral in siliceous phosphate ore. To obtain efficient concentration of phosphate minerals, the flotation separation of quartz and collophane using AY as a collector was studied in this paper.
The computer based method of solution of the set of equations gives an access to obtain the effective non linear stiffnesses of 4th order. The measurements and computer solutions are performed on different Y cuts resonators, both for quartz and gallium phosphate resonators, vibrating in fundamental thickness shear mode.
See the answer. An industrial mining process uses electrostatic forces to separate small particles of quartz from small particles of phosphate. Both particle types are preprocessed so that they are clean, dry, have diameters of approximately 2.5e 01 mm , and have charge to mass ratios of approximately Q/m = 1e 05 C/kg. They fall from a vibrating hopper through a constant electrostatic field of E = 1e+05 ûx V/m, generated by an applied voltage potential of V.
Homogenates were prepared by using a mortar and sterile quartz to grind the tissue samples. The homogenates were then diluted in phosphate buffered saline, and tissue debris was removed by low speed centrifugation.
Phosphate ν 4 P O vibrations were located at 565 and 598cm 1 , which appear in the SB/RB+PSB+Pb treatments. The CO 32 rocking deformation peak was due to cerussite/hydrocerussite formed on RB+Pb and SB+Pb after Pb 2+ adsorption .

The present invention concerns itself with crystallographically doubly rotated quartz orientations vibrating in the transverse c mode with turnover temperatures which are considerably less sensitive to angular misorientation than the comparable well known AT or BT cuts.
Crushed Florida phosphate ore consists of particles of quartz mixed with particles of phosphate rock. Vibrating the mix ture results in positively charged phosphate and negatively charged quartz components. Pouring the mixture through a horizontally directed electric eld allows the phosphate to be separated out. Over what minimum distance must ...
