Abstract: Calcium oxide particles are suspended in an inert, water-insoluble, organic carrier liquid. While the suspension is agitated, phosphoric acid and water are added whereby to form agglomerates consisting of dicalcium phosphate useful in animal feeds.

Abstract: An aqueous pulp or slurry containing cement copper particles is treated with conditioner and hydrophobic bridging liquid to form agglomerates of the cement copper particles, which agglomerates are then separated from the aqueous phase.

Abstract: The aqueous slime waste product of a phosphate ore beneficiation process is dewatered by agglomerating the solids thereof using a conditioner and a hydrophobic bridging liquid.

Abstract: An aqueous dispersion of a clay is dewatered and the clay solids thereof are agglomerated using a conditioner and a hydrophobic bridging liquid.

Abstract: Steel mill wastes are treated to recover the iron values thereof by a two stage agglomeration process wherein relatively small size first agglomerates are formed by agglomeration of steel mill wastes from an aqueous suspension thereof and then relatively large size second agglomerates are formed by agglomeration of said first agglomerates from a suspension thereof in a hydrophobic organic liquid and simultaneously a reactant chemical reacts with the agglomerates to provide a solid binder material formed in situ during the second agglomeration procedure.

Abstract: An aqueous dispersion of a clay is dewatered and the clay solids thereof are agglomerated using a conditioner and a hydrophobic bridging liquid, and then pellets are formed of the clay agglomerates.

Abstract: Finely divided sulfur particles in a liquid suspension are agglomerated by adding molten sulfur to the suspension and agitating the mixture to transform the particles into agglomerates wherein the finely divided sulfur particles are held together by the previously molten, now solidified sulfur, acting as a binder agent.

Abstract: Method of agglomerating solids in a liquid suspension utilizing in the bridging liquid an additive chemically active with respect to such solids. The solid to be agglomerated is suspended in a first liquid which is, or is made to be, at least relatively nonwetting with respect thereto. A second immiscible or bridging liquid is then introduced into said first liquid. Said second liquid is, or contains dissolved therein material which is, reactive to such solid material. The entire system is then agitated and the solid material thereby formed into agglomerates. The use of a chemically reactive material in the bridging liquid provides a wide range of selectability of and control over the properties, either physical or chemical, of the resulting agglomerates.

Abstract: Excellent adhesion of vitreous enamel to steel can be achieved via an intermediate layer formed on the steel by bringing it into contact with a liquid composition that contains water and a component of solute selected from the group consisting of dissolved silicates and dissolved borates and, optionally, surfactant. The modification of the steel surface achieved by treating it with silicates and/or borates is also effective for improving the adhesion of steel to other protective type coatings such as paint.
