Latest Patents

Hal G Smith holds a patent for a process titled "Treatment of mineral materials." This invention involves a method where material comprising an aqueous liquid with dispersed particulate solids is pumped as a fluid. The process allows the material to stand and rigidify, improving the rigidification while retaining the pumpability by combining polymeric particles with the material during or prior to pumping. The polymeric particles used are water-soluble polymers with an intrinsic viscosity of at least 3 dl/g. This invention is particularly effective in minimizing the area taken up by a stack of material of a given volume while maintaining its pumpability. It is especially suited for materials that include red mud from the Bayer alumina process.
