Abstract
The maximum value of the profit response was obtained with the highest possible values of acid concentration (2.5â¯M) and time (2â¯h), a liquid/solid ratio of 5â¯L/kg, and the lowest possible value of temperature (40â¯Â°C). After leaching, the electrodes active material contained in the metals decreased, while it was still significant in the graphite, as observed by scanning electron microscopy-energy dispersive spectrometry and x-ray powder diffraction. Even though the performed economic evaluation was a summarized outline it can be considered suitable to compare different leaching conditions and to determine the possible best combinations of factors that can optimize the profit response.
