Abstract: Toxic substances such as heavy metals are extracted from a medium using a sorbent composition. The sorbent composition is derived by sulfidation of red mud, which contains hydrated ferric oxides derived from the Bayer processing of bauxite ores. Exemplary sulfidizing compounds are H2S, Na2S, K2S, (NH4)2S, and CaSx. The sulfur content typically is from about 0.2 to about 10% above the residual sulfur in the red mud. Sulfidized red mud is an improved sorbent compared to red mud for most of the heavy metals tested (Hg, Cr, Pb, Cu, Zn, Cd, Se, Th, and U). Unlike red mud, sulfidized red mud does not leach naturally contained metals. Sulfidized red mud also prevents leaching of metals when mixed with red mud. Mixtures of sulfidized red mud and red mud are more effective for sorbing other ions, such as As, Co, Mn, and Sr, than sulfidized red mud alone.

Abstract: A method and composition for controlling an exothermic reaction between a powerful oxidizing agent such as the permanganate salts, and reducing agents such as polyhydroxy organic compounds, comprises non-charged, relatively hydrophobic pigments which can be slurried at relatively high solids. The pigment may be calcium carbonate, diatomaceous earth (diatomite), talc, or blends thereof. The pigments are not flocculated in permanganate slurries and can be dispersed at high solids contents. The dispersions can be spray dried or pelletized with controllable moisture contents from about 0.1 to 10%. The resulting composition yields effective control of the exothermic reaction with more uniform and reproducible results.
