1. A method for separating soft-burned quicklime from hard-burned quicklime, the method comprising:
providing a quicklime particulate with a particle size smaller than 100 mesh, the quicklime particulate having a size distribution with two peaks in a bimodal distribution; and
running said quicklime particles through a classifier to separate said quicklime particles into a soft burned and a hard burned fraction separated by a dividing point, said soft burned fraction being particles smaller than said dividing point and said hard burned fraction being particles larger than said dividing point;
wherein said dividing point is between said two peaks in said bimodal distribution.
