    摘要: A medical imaging support includes a substantially flat radiotransparent platform, a plurality of radiotransparent flaps, and closure mechanisms. The platform has a longitudinal direction between a top edge and a bottom edge. The plurality of sets of radiotransparent flaps have a first set of the radiotransparent flaps positioned closer to the top edge in the longitudinal direction than the second set of radiotransparent flaps, and at least one set of flaps includes a first flap and a second flap where the first flap is fixed to the platform proximate a first side edge and the second flap is fixed to the platform proximate a second side edge. The closure mechanisms are positioned on the first flap or second flap of each set of radiotransparent flaps, wherein the closure mechanism selectively fixes the first flap to the second flap of each set of radiotransparent flaps.

    摘要: Methods for recovering metals from metal-containing materials are provided. The metal-containing material comprises either Co and Li (e.g., an electrode material from a spent lithium ion battery) or Fe and Al (e.g., bauxite). The metal-containing material is exposed to a leaching solution comprising ammonium hydrogen oxalate, oxalic acid, or both, to provide a solid composed of either cobalt oxalate or iron oxalate, and a solution of either lithium oxalate or aluminum oxalate. The solid is processed to provide either cobalt oxide or iron oxide; the solution is processed to provide either a lithium precipitate or an aluminum precipitate, and a filtrate comprising an oxalate; and the filtrate comprising the oxalate is processed to recover ammonium hydrogen oxalate, oxalic acid, or both. The method further comprises repeating the digestion step with the recovered ammonium hydrogen oxalate, the recovered oxalic acid, or both.
