摘要： 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.

摘要： There are disclosed method and compositions for reducing the viscosity of phosphate matrix slurries and improving consolidation characteristics of slimes resulting from the beneficiation of the slurries. An unexpectedly greater degree of viscosity reduction and clay consolidation characteristics improvement is obtained by adding the compositions to the water utilized to slurry the phosphate matrix prior to the information of the slurries. The compositions include water-soluble compounds, such as organic acids, mineral acids, monovalent inorganic salts and polyvalent inorganic salts.
