The ECO REFRACTORY SOLUTIONS INC. hydrometallurgical process is expected to provide numerous benefits. Capital and operating costs are projected to be significantly lower than other methods. The process is in large part a closed system regenerating and recycling the principal reagents. In addition, problems related to the release of arsenic into the environment and acid mine drainage are solved by the transformation of the arsenic and the oxidation of sulphides into environmentally stable forms.
