Polymer Beads Containing An Immobilized Extractant For Sorbing Metals From Solution
US Patent:
5279745, Jan 18, 1994
Filed:
Dec 26, 1991
Appl. No.:
7/818427
Inventors:
Thomas H. Jeffers - Salt Lake City UT
Don C. Seidel - Salt Lake City UT
Don C. Seidel - Salt Lake City UT
Assignee:

Interior - Washington DC
Interior - Washington DC
International Classification:
C02F 142, C12N 1112, C12N 1104, B01J 1302
US Classification:
210688
Abstract:
Polymer beads are prepared containing an immobilized extractant for sorbing metal contaminants at concentrations of less than 1 mg/L in dilute aqueous solutions. A preferred polymer is polysulfone and the extractant can be a biomass material or a synthetic chemical compound sorbed into activated carbon. The polymer beads are prepared by dissolving the polymer in an organic solvent to form a solution, adding the extractant to the solution to form a mixture and injecting the mixture through a nozzle into water to form the beads.
Froth Flotation Of Insoluble Slimes From Sylvinite Ores
US Patent:
4192737, Mar 11, 1980
Filed:
Sep 15, 1978
Appl. No.:
5/942833
Inventors:
Philip Thompson - Salt Lake City UT

Interior - Washington DC
International Classification:
B03D 102
US Classification:
209 5
Abstract:
Sylvinite ores are treated for removal of insoluble slimes by a froth flotation technique which includes flocculating the slimes with nonionic or polyacrylamide flocculants and thereafter utilizing a nonionic or an anionic flotation collector including a mixture of fuel oil or a fatty acid and a defoamer of the glycol ester or polyglycol ester type. The flocculated slimes may also be floated with a fatty acid collector alone at low pH conditions.
