Amine aldehyde Resins modified by processes of selective separation of solids and / or Ionic species from an aqueous medium

摘要

The processes include where froth Flotation of Minerals (Benefit includes a material selected value of phosphate, sulphate, Lime, gypsum, Synthetic gypsum, fe, PT, au, PD, Cu, ti, MO, u, CR, W, MN, mg, Pb, Zn, AG, Clay, Coal, Graphite, Nickel, Bauxite, and impurez or borax borate; Or more selected Sand, Clay, iron oxide, Titanium Oxide,Titanium Bearing Ilmenite, Iron, mica, tourmaline, Aluminum silicate, Calcite, Dolomite, Anhydrite, ferromagnesio, Feldspar, CALCIUM MAGNESIUM CARBONATE, Igneous Rock, soil, Hg, CD, Pb, as, S, N, Silicon ash and pyrite), Separation of chips Drill drilling fluids P Etroleo, Dewatering of Coal and Clay Slurry, Sewage Treatment,Processing Plant effluent of Pulp and Paper, removal of Sand and bitumen into Drinking Water Purification.The Resins comprise a Resin product of the reaction of a primary or secondary Amine and ALDEHYDE (Urea formaldehyde resin), which is modified with a Silane coupling Agent (silica, SILANE or polysiloxane substituted silicate) During or after its preparation. Is replaced with the ureido SILANE, amino, epoxy, Vinyl, metacrilo, alkyl or haloalquilo.The Resins also comprise a chelating Agent (DTPa, EDTA, HEDTA, DTPA and NTA, oxalic acid, amino acid, arginine, cysteine, Serine, alanine, caprolactam, tiosemicarbazida or diacetyl bis - (N - metiltiosemicarbazona))
