Methods for preventing or reducing the formation of scale in a wet-process phosphoric acid production process by intermixing a water-soluble functional organic reagent with a phosphoric acid at one or more step of the phosphoric acid production process in an amount sufficient to prevent or reduce at least one species of scale are provided.
摘要:
A process for the beneficiation of carbonate mineral substrates by magnetic separation is defined herein wherein a phosphorus or nitrogen containing organic compound or reagent and a plurality of magnetic particles are intermixed with a carbonate containing mineral substrate, a magnetic field is applied to the mixture and a value mineral is thereby separated from a non-value mineral.
摘要:
A magnetic reagent contains magnetic microparticles and a compound of the formula (I) as defined herein. The magnetic reagent may be used in a magnetic separation process for the removal of impurities from mineral substrates.
摘要:
A structured composite pigment composed of TiO.sub.2, calcined clay and polyaluminum chloride (PAC). A novel process is disclosed for producing an aggregated composite premium pigment having superior optical, physical and dispersion characteristics for papermaking applications. The aggregated pigment is produced by chemically aggregating a mixture containing TiO.sub.2 and calcined clay with polyaluminum chloride of a basicity of 10-85% in alkaline conditions of pH 8.5-10.5.
摘要:
This invention discloses a process of making composite aggregate pigments (CAPs) having superior optical and dispersion characteristics. These pigments are produced by aggregating titanium dioxide and calcined clay with zirconium hydroxy complex chemicals in a slurry in the pH range of 6.0-10.5. Superior optical properties are obtained by heat treating the pigments after removal from the slurry. Multi-faceted pigments are obtained by including a small amount of a rod-shaped pigment, such as wollastonite, in the composite pigment.
