A back plate having a stationary back electrode is secured to a substrate. The battery can be attached to and detached from the battery support in a length direction of the battery. The capacity adjustment unit may operate in association with the size adjustment guide so as to define the loading position based on the size of the printing media. The macroinstructions are rewritten as strings according to a second computer system language. In accordance with the various aspects of the present invention, metal-containing pregnant leach solutions from pressure leaching operations need not be significantly diluted to facilitate effective metal recovery using solvent extraction and electrowinning.
