1. A process for the treatment of a waste material containing a first species having a high alkalinity and/or pH, comprising the steps of (a) contacting the waste material with an amount of a first treatment material sufficient to cause at least some of the said first species to be inactivated, thereby resulting in a treated waste material;

  • (b) separating the solid and liquid phases in the mixture of waste material and treating material; and

    (c) thereafter contacting the separated liquid phase with a sufficient amount of a second treatment material having a low pH, so as to cause the pH of the waste material to be reduced to an environmentally acceptable level.
