Publication number: 20060249432Abstract: The invention provides an agitator (1) is disposed to agitate slurry within a flotation tank (2). The agitator includes a rotor (6) mounted on one end of a centrally disposed drive shaft (7) extending axially downwardly into the tank and driven by a motor (8) and associated gearbox (not shown). The other end of the drive shaft includes a mounting flange (9) adapted for connection to the motor. A stator (10) is also provided around the rotor. A froth deflection cone (11) extends around the drive shaft adjacent the top of the tank. The deflection cone is oriented such that its smallest diameter is located at its lower-most end nearest the rotor (6). An auxiliary agitator (12) is connected to the drive shaft at a position substantially midway between the underside of the deflection cone (11) and the top of the rotor (6), as shown in FIG. 1 and FIG. 2. The auxiliary agitator (12) includes agitation blades (13) extending radially outwardly from diametrically opposite sides of the shaft (7).Type: ApplicationFiled: March 16, 2004Publication date: November 9, 2006Inventor: Peter Bourke

Publication number: 20060219603Abstract: The invention provides a flotation device including a series of flotation tanks (1) for processing a slurry incorporating valuable minerals for extraction. At least one of the tanks includes a side outlet (15) adapted for the withdrawal of targeted relatively fine coarse particles from the slurry. The tanks also include a bottom outlet (14) for the withdrawal of relatively dense or coarse components of the slurry. The incorporation of bottom and side outlets allows the slurry to be separated into two parallel streams, one configured for optimal recovery of the relatively coarse or dense slurry components and the other for optimal recovery of the relatively fine slurry components. In this way, outflow slurry from downstream tanks in the coarse particle stream has a higher proportion of coarser particles than was present in the inflow slurry from the upstream tanks.Type: ApplicationFiled: March 16, 2004Publication date: October 5, 2006Inventor: Peter Bourke

Patent number: 6926154Abstract: The invention relates to a flotation machine which at least contains a flotation cell having a means for feeding slurry in the flotation cell, a means for feeding air into the slurry and producing froth, a means for removing froth from the flotation cell and a means for removing tailings from the flotation cell. According to the invention the flotation cell (1,21) is provided with at least one rotating froth removal device (8,26) immersed at least partly in the froth (9,27) and so shaped that one end of the froth removal device (8,26) is extendible over the launder (12) attached to the flotation cell (1) in order to recover the froth (9,27) from the flotation cell (1,21) using the centrifugal force generated by the froth removal device (8,26).Type: GrantFiled: December 11, 2001Date of Patent: August 9, 2005Inventors: Peter Bourke, David Taylor

Patent number: 6772885Abstract: The invention relates to a rotor used in the flotation mechanism in the concentration of ores. According to the invention, upper part of the rotor chambers under the rotor cover are formed to be downward inclined from the outer edge of the chambers into the core so that they form an angle between 5 to 70 degrees with the horizontal plane. In addition the upper surface of the rotor cover can be inclined upwards raising from around the rotor shaft towards the outer edge at an angle between 5-70 degrees. With the means inside and above the rotor the slurry is directed upwards through the stator of the flotation mechanism. The developed rotor improves the suspension of coarse particles with high specific gravity within a flotation machine. The invention relates also to a method for inverting the material flow disharging from the rotor.Type: GrantFiled: September 19, 2003Date of Patent: August 10, 2004Assignee: Outokumpu OyjInventor: Peter Bourke
