Latest Patents

Gerald Smith holds a patent for a "Method for bleaching kaolin clay." This patent describes an improved method for enhancing the brightness of clay that can be bleached using an oxidative reagent, such as Georgia gray kaolin. The process involves treating the clay, in the form of a dispersed slurry, with a combination of an inorganic condensed phosphate, sodium hypochlorite, and ozone. The method includes separate treatment steps of magnetic purification and reductive bleaching. Suitable phosphates for this process include sodium hexametaphosphate, sodium tripolyphosphate, and tetrasodium pyrophosphate. The hypochlorite is added shortly before ozonation, while the phosphate can be introduced before, simultaneously with, or after the hypochlorite.
