Abstract: This disclosure relates to systems and methods for the dissolution of metals, metallic compounds, metallic alloys, metallic solids, recyclable metal, semiconductors, and the like. Particularly disclosed, are exemplary systems, methods, and apparatus for leaching metallic solids such as blister copper, scrap copper anode, scrap copper cathode, and recycled/scrap copper. A hydrometallurgical leach process (130, 230, 730) may be provided in lieu of, or in addition to conventional electro-refining (914, 214) and fire-refining (911, 211) operations, in order to supplement and/or increase copper cathode production. Impure metallic solids are rapidly and selectively dissolved into solution via a mechano-chemical exothermic leach process, in a mechano-chemical (M-C) leach reactor. In some embodiments, impure metallic copper is rapidly and selectively dissolved into dilute sulfuric acid (e.g., 1-2 M H 2 SO 4 ); wherein the mechano-chemical dissolution process is exothermic and produces a concentrated copper sulfate electrolyte that can be used to increase existing electrorefinery output, while simultaneously eliminating the need to recycle anode scrap back to a fire refinery (911). The disclosed processes may potentially eliminate fire refining (914, 214) steps altogether, for example, by processing blister copper directly, in order to produce a copper electrolyte (113, 222, 722) for cathode (116, 225, 725) production via electrowinning.
