Abstract: A method for leaching a metal-bearing material is provided. The method includes leaching a metal-bearing material, comprising leaching the metal-bearing material with a leaching solution to produce a pregnant leaching solution, wherein the leaching solution comprises a raffinate and a sulfinate compound, wherein the sulfinate compound produces a decomposition product, and wherein the decomposition product interacts with a passivating material at a surface of the metal-bearing material, improving recovery of a metal value from the metal-bearing material.

Abstract: A method for leaching a metal-bearing material. The method comprises leaching the metal-bearing material with a leaching solution to produce a pregnant leaching solution, wherein the leaching solution comprises a raffinate and an alkyl thiosulfonate compound, wherein the alkyl thiosulfonate compound undergoes decomposition in the leaching system, and wherein the decomposition of the alkyl thiosulfonate compound lowers oxidation-reduction potential of the leaching system, improving recovery of a metal value from the metal-bearing material.

Abstract: An apparatus and method for cutting blocks of frozen food into irregular shapes comprises a slicer unit carrying a cutting blade and chutes for feeding logs of frozen food to said blade. The chute extends from a chute inlet to a chute outlet, having a central longitudinal axis extending from the center of the chute inlet to center of chute outlet. The cutting blade is positioned below the chute outlets wherein said elongate blocks of processed food are fed into said chute inlet through the chute to the chute outlet, to said blade, said blade sectioning the blocks into smaller pieces. The chutes are angled greater than 15 degrees and less than 90 degrees from the plane of the cutting blade and the chute is rotated about its longitudinal axis between 0 to 180 degrees from a square orientation to the plane of the blade.
