Abstract:
A method and apparatus for the recovery of hydrophobic particles from a slurry comprised of water, the hydrophobic particles, and a hydrophilic component. Slurry is exposed to a gas stream to permit bubbles to adhere to the hydrophobic particles. The slurry generally flows vertically through a vessel at a velocity that maintains gas hold-up at least between 30 and 70% to maintain a bubbly flow without a slurry froth interface so that a portion of the water of the slurry, together with entrained gas bubbles attached to hydrophobic particles, flows out of the vessel with a portion of the water of the slurry and the hydrophilic component remaining in the vessel. Water from the slurry and gas bubbles attached to hydrophobic particles flowing through the vessel is discharged and collected for processing. A portion of the hydrophilic component is extracted as tailings for disposal or subsequent processing.

Claim (Index 19):
The apparatus as claimed in  claim 10  wherein the direct flotation vessel comprises,\n (i) a first conical section having a first end of a diameter larger than a second end, said first end of said first conical section comprising said intake end of said direct flotation vessel and in fluid communication with the bubble engagement tank, \n (ii) a first pipe section of a generally constant diameter approximating the diameter of said second end of said first conical section, said first pipe section having an upstream end in fluid communication with said second end of said first conical section \n (iii) a second conical section having an upstream end of a diameter larger than a downstream end, the diameter of said upstream end of said second conical section approximating the diameter of said first pipe section, said upstream end of said second conical section in fluid communication with a downstream end of said first pipe section, and \n (iv) a second pipe section having a first end, in fluid communication with said downstream end of said second conical section, and having a second end comprising said discharge end, \n said control valve operatively connected to said second end of said second pipe section.
