Abstract:
    A stabilized aqueous slurry of lime and a method for preparing the same are provided. The method involves stabilizing an aqueous lime slurry of from about 20 to about 60 percent by weight lime with from about 0.05 to about 10 percent by weight based on the weight of lime of one or more polymeric anionic dispersants and salts thereof. Polymeric anionic dispersants include homopolymers, copolymers and terpolymers of acid functional monomers. Slurries prepared according to the invention remain flowable after several days.
