This was achieved with the H 2 SO 4 activation and polishing leach. In addition, once the plant is up and running, the research program on the development of the valorization of the carbon-brick fraction beneficiates. The carbon-brick fraction can be separated by flotation and could yield a high-value carbon; the brick can be used in cement kiln.
