The process of the present invention relates to a simplified method for the removal of halogen containing catalytic residues from olefin polymerization products. More specifically, the present invention employs as a treating agent, a quaternary ammonium salt, to facilitate removal of greater than 95% of catalytic residues in a single caustic or water wash with less than 15 minutes of settling time required after the wash.

Process for the removal of catalyst residues from olefin polymerization

There is disclosed a method of producing water-based phosphate matrix slurries wherein the as-mined phosphate matrix is dried prior to the formation of the slurry. Drying the matrix decreases the viscosity of the slurry and improves the clay consolidation characteristics of the by-product slimes produced during the phosphate slurry beneficiation process steps.

Treatment of phosphate ore used in preparing phosphate matrix slurries

The invention provides a new and improved process for beneficiating ores which comprises a single cationic float using an etherdiamine as the cationic collector following washing the feed with aqueous alkali metal silicate.
