Abstract: A method of recovering metal compounds from solid oxide fuel cell scrap includes processing the solid oxide fuel cell scrap to form a powder, digesting the processed scrap, extracting lanthanum oxide and cerium oxide from a solution containing the digested processed scrap, extracting a zirconium compound from the solution after extracting the lanthanum oxide and cerium oxide, and extracting scandium compound from the solution extracting the zirconium compound from the solution.

Abstract: A method of selectively removing impurities from a scandium-containing feed solution includes contacting an aqueous scandium-containing solution with an organic solvent stream containing an extractant, thereby forming a loaded organic solvent stream containing the impurity or impurities while leaving the scandium in the raffinate. The aqueous stream containing the scandium is washed, diluted and has inorganic salts added before being contacted with a second organic solvent stream to extract the scandium selectively, and followed by stripping the scandium from the scandium-containing loaded organic extractant stream by adding oxalic acid to the loaded organic extractant stream to form scandium oxalate.

Abstract: A vehicle truck box assembly including a tailgate, a hinge-on-box bracket, a puck component, a hinge post, and a plastic shim is provided. The tailgate is pivotally mounted to a truck bed. The hinge-on-box bracket includes a cup extension. The puck component is secured to the cup extension. The hinge post is for securing to the puck component and to a hinge-on-gate bracket and the hinge post defines a cavity. The plastic shim is received in the cavity for contacting the cup extension. The plastic shim may include an upper angle portion extending from a base portion. The upper angle portion may extend between the cup extension and the puck component that are arranged to snugly receive the hinge post. The upper angle portion may extend from the base portion at an angle value between five and fifteen degrees.

Abstract: A method of selectively removing scandium from a scandium and fluoride-containing feed material includes providing the scandium-containing feed material, acid leaching the scandium-containing feed material with at least one acid in a presence of at least one of an aluminum or iron containing salt to form a scandium containing stream, and purifying the scandium containing stream to form a scandium compound end product.

Abstract: A method of selectively removing impurities from a scandium-containing feed solution includes contacting an aqueous scandium-containing solution with an organic solvent stream containing an extractant, thereby forming a loaded organic solvent stream containing the impurity or impurities while leaving the scandium in the raffinate. The aqueous stream containing the scandium is washed, diluted and has inorganic salts added before being contacted with a second organic solvent stream to extract the scandium selectively, and followed by stripping the scandium from the scandium-containing loaded organic extractant stream by adding oxalic acid to the loaded organic extractant stream to form scandium oxalate.

Abstract: A method for selectively removing scandium from a scandium-containing feed solution includes contacting the scandium-containing feed solution with a solvent stream in plural stages using cross current extraction, in which the solvent is loaded with at least a portion of the scandium from the feed solution, and/or ion exchange, and separating the loaded solvent from remaining scandium-containing feed solution.
