✦ Synopsis

Control of heteroflocculation using a lower molecular weight fraction of the flocculant as a site blocking agent is demonstrated in the apatite-dolomite-polyethylene oxide system. The most effective SBA (site blocking agent) was determined to be the highest molecular weight fraction of the focculant itself which was not capable of flocculating any of the components of the mixture. In the presence of the SBA, flocculant adsorption decreased significantly on apatite particles, thereby inhibiting coflocculation. 1993 Academic Press. Inc.
