Abstract:
This disclosure describes systems, methods, and apparatus for counter-current solids leaching. A multi-stage countercurrent leaching chamber can include a top and bottom end, a barren liquor input, two or more regions for countercurrent mixing, and a barren solids output. The input can be configured to receive barren liquor. The two or more regions for countercurrent mixing and separation can be configured to mix and separate liquid and solid phases. The barren solids output can be configured to collect and discharge barren solids from the bottom end of the multi-stage countercurrent leaching chamber. A fluidized bed chamber and clarifier chamber can also be included, where the fluidized bed receives a fluidizable slurry of pregnant solids and the clarifier chamber aids in separating liquids from solids passing from a top of the fluidized bed chamber to the top end of the multi-stage countercurrent leaching chamber.

Claim (Index 11):
A method for leaching fine solids, the method comprising:\n receiving barren liquor and pregnant solids near a bottom of a fluidized bed to form a mixture; fluidizing the mixture to form a fluidized mixture that moves toward a top of the fluidized bed; the fluidized mixture entering a region near a top of the fluidized bed that is shared with a top of a multi-stage countercurrent leaching chamber, the region having a larger cross section than a cross section of either the fluidized bed or the multi-stage countercurrent leaching chamber alone; receiving a leach or wash solution near a bottom of the multi-stage countercurrent leaching chamber; allowing the pregnant solids to descend within the multi-stage countercurrent leaching chamber via the force of gravity; separating solids and liquids via multiple mixing and separating stages of the multi-stage countercurrent leaching chamber; collecting and discharging barren solids from a bottom of the multi-stage countercurrent leaching chamber; and collecting and discharging pregnant liquor from a clarifier arranged atop both the fluidized bed and the multi-stage countercurrent leaching chamber.
