청구항

[ I claim:] [1.] A method for recovery and use of a particulate material present in an aqueous suspension derived from an industrial waste material, said material comprising inorganic and/or organic solid fines constituting at least 0.5% by weight of the suspension, wherein the inorganic fines have an average size less than about 50 .mu.m and the organic fines have a length such that they will pass through a round hole of diameter 76 .mu.m, comprising the steps of:a) introducing into the aqueous suspension a reagent comprising a source of alkaline earth ...
