Abstract
Abstract Apparatus for treating ore pulp in a treatment cell attendant to recovery of minerals therefrom, the apparatus having a rotatable shaft with an attached impeller. A stabilizer device is joined to the cell adjacent the impeller so that a shear zone is developed in the ore pulp, the stabilizer device being configurated to maximize turbulence in the shear zone and minimize surging and boiling of the ore pulp at the surface thereof.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
133 words
A device for use in a mineral recovery flotation cell comprising: vat means into which mineral-bearing pulp and treatment material are placed; circulation means comprising rotatable, shaft means extending generally vertically into the interior of the vat, and impeller means non-rotatably attached to the shaft means within the interior of the vat and rotatable with the shaft means to cause continuous suspension of mineral in the pulp; stationary stabilizer means horizontally spaced from and circumferentially disposed around the impeller means within the interior of the vat, the stabilizer means comprising a plurality of spaced blades each having radially and vertically disposed edges and at least one curved surface the axis of curvature being generally horizontal against which the pulp and air within the pulp are displaced by the impeller to improve mineral recovery.
Claim 2
Independent Claim
133 words
A device for use in a mineral recovery flotation cell comprising: vat means into which mineral-bearing pulp and treatment material are placed; circulation means comprising rotatable, shaft means extending generally vertically into the interior of the vat, and impeller means non-rotatably attached to the shaft means within the interior of the vat and rotatable with the shaft means to cause continuous suspension of mineral in the pulp; stationary stabilizer means horizontally spaced from and circumferentially disposed around the impeller means within the interior of the vat, the stabilizer means comprising a plurality of spaced blades each having radially and vertically disposed edges and at least one curved surface the axis of curvature being generally horizontal against which the pulp and air within the pulp are displaced by the impeller to improve mineral recovery.
Claim 3
Dependent Claim
37 words
The device of claim 1 wherein the stabilizer blades each have two opposed concave surfaces the axis of curvature extending in a generally horizontal direction thereby accommodating improved agitation upon rotation of the impeller in either direction.
Claim 4
Dependent Claim
20 words
The device of claim 1 wherein at least one stabilizer blade comprises an inner metal core disposed within resilient material.
