Abstract
Abstract An inclined static deoiler and conditioner for treating ore such as coal, phosphate, and the like which combines with liquid to form a slurry prior to froth floation which includes in combination a trough having plural baffles therein which are oriented to cause turbulence in the slurry. End walls on the trough are provided having an inlet and outlet adapted to fasten to piping in which the maximum flow rate is determined by the piping diameter such that liquid entering in the trough is assured of staying substantially at or below the vertical height of the baffles. The through flow within the device is controlled by angulation of the trough which is variable, and baffle configuration.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
82 words
An inclined static deoiler and conditioner for treating ore in liquid prior to and after froth flotation comprising in combination: a trough means, first baffle means oriented to cause turbulence on the liquid/ore in said trough said first baffle means formed from two ply material provided with an interior air space between said plies, end walls on said trough having an inlet and an outlet adapted to fasten to piping, and means to angulate said trough to alter the liquid flow rate.
Claim 2
Dependent Claim
82 words
An inclined static deoiler and conditioner for treating ore in liquid prior to and after froth flotation comprising in combination: a trough means, first baffle means oriented to cause turbulence on the liquid/ore in said trough said first baffle means formed from two ply material provided with an interior air space between said plies, end walls on said trough having an inlet and an outlet adapted to fasten to piping, and means to angulate said trough to alter the liquid flow rate.
Claim 3
Dependent Claim
33 words
The device of claim 1 wherein said outlets are equally dimensioned relative to the vertical height of said baffle means so that the liquid/ore flow stays substantially at or below said vertical height.
Claim 4
Dependent Claim
15 words
The device of claim 2 wherein said first baffle means are inclined toward said inlet.
Claim 5
Dependent Claim
33 words
