    摘要： A fluid jet flotation apparatus 1 is disclosed. The apparatus 1 comprises a tank 10 containing a liquid having a relatively lower region and a relatively upper region and a conduit 2 having a liquid inlet 5 through which a particle-containing liquid is introduced to the conduit 2 as a jet. The conduit 2 also includes a gas inlet 6 through which gas is drawn into the conduit 2 by the jet, the liquid and the gas forming a foam bed that is displaced through the conduit 2 and out through an outlet 24 remote from the inlet 5. The outlet 24 is positioned to discharge the foam bed from the conduit 2 into the tank 10 in an upward direction and in a relatively upper region of the tank. This enhances the separation of value particles in the froth from waste particles in the body of liquid. Further, the reduced pressure at the outlet 24 of the conduit 2 enhances the draw and thereby the volumetric throughput through the conduit 2. In the drawing the conduit comprises a downcomer and then a riser extending up from the downcomer. The apparatus also includes a froth recovery means for recovering particle laden froth from a froth layer that forms above the liquid in the tank 10. The tank 10 has a peripheral wall 11 with an upper edge defining a top that opens to the atmosphere and the froth recovery means comprises an overflow weir 15 formed by said upper edge of the tank 10 over which the froth layer can be discharged from the tank 10.

    摘要： The present invention provides a process that employs both non-selective flotation and oxidative leaching of the resulting concentrates to recover an increased amount of copper from porphyry copper ores. The non-selective flotation step uses collectors and conditions, such as pH, that are conducive to the strong flotation of sulfide minerals generally. In the oxidative leach, the copper sulfide minerals in the concentrate fraction are oxidized to copper compounds, which are soluble in the leach solution. The oxidative leach includes the use of ammonia and sulfite under agitation leaching conditions to convert the copper sulfide minerals into ammonia soluble forms.

    摘要： A method for treating a liquid flow to be cleaned passing through a flow line into a flotation plant including passing a portion of the liquid flow to be cleaned from the flow line along a first branch line into a pump. The suction capacity of the pump is regulated to draw in a direct flow of gas so that the pump sucks the gas as a direct flow. The drawn-in direct flow of gas is then mixed with the liquid flow in the pump and passed along a discharge pipe of the pump into a mixing part wherein the discharge pipe ends in a pressure release. The remaining portion of the liquid flow to be cleaned from the flow line is then passed along a second branch line into the mixing part. A liquid flow is discharged from the pressure release, the liquid flow including gas bubbles containing dissolved gas. The remaining portion of the liquid flow to be cleaned is then mixed with the liquid flow discharged from the pressure release to obtain a resultant flow which is then passed along a mixing duct into the flow line and further into the flotation plant.

    摘要： A device for suspending solid particles in a turbulent fluid for the purpose of concentrating particles of interest such as mineral particles comprises an upright column provided with a plurality of impellers spaced along a rotatable shaft extending centrally within the column. An inlet is provided near the bottom of the column to introduce compressed gas which is dispersed by the rotating impellers to create a rising column of bubbles through a slurry of particles in a liquid so that a gas to liquid gradient is provided along the column. Disks are spaced along the shaft between the impellers, and baffles are provided longitudinally at the inner surface of the column to control the swirling of the fluid caused by the impellers.

    摘要： In deinking, the flotation of fiber suspensions is performed in a cylindrical tank 2 to which the fiber suspension is fed through a coupling means 36 as primary stream. The fiber suspension is already aerated and is withdrawn through a suction connection 33 below the coupling means 36 and fed after another aeration through a secondary connection 35 above the coupling means. The volume of the circulated secondary stream is greater than the volume of the primary stream. It is thereby assured that the fiber suspension is aerated at least twice and thus better cleaned.
