    Depressant function of high molecular weight polyacrylamide

    A high molecular weight polyacrylamide (PAM) was tested as a potential selective depressant in the differential flotation separation of galena and chalcopyrite using potassium ethyl xanthate (KEX) as a collector. In single mineral flotation, PAM depressed chalcopyrite while galena was floatable.

    Polyacrylamide gel electrophoresis - Wikipedia

    Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) is a method of separating molecules based on the difference of their molecular weight. At the pH at which gel electrophoresis is carried out the SDS molecules are negatively charged and bind to proteins in a set ratio, approximately one molecule of SDS for every 2 amino acids.

    Anionic and Nonionic Polyacrylamides

    Anionic high molecular weight polymers are used for flocculating negatively charged particles by interaction with suitable cationic adsorption sites e.g. Ca 2+, Mg 2+, Al 3+, Fe 2+ and Fe 3+. Nonionic polyacrylamides are very effective in mineral and textiles processing applications.

    The Use of Polyacrylamide as a Selective Depressant in the

    High molecular weight polyacrylamide (PAM) was tested as a potential selective depressant in the differential flotation separation of galena and chalcopyrite using potassium ethyl xanthate (KEX) as a collector. In single mineral flotation, PAM depressed chalcopyrite while galena was floatable. Mechanism study indicated that PAM could adsorb on galena through hydrogen bonding, and on

    Properties of Polyacrylamides

    Polyacylamides are high molecular weight water soluble or swellable polymers formed from acrylamide or its derivatives. Their glass transition temperature is well above room temperature (> 400 K). The only commercially important polyacrylamide is poly(2-propenamide) which is simply called polyacrylamide or PAM [-CH 2 CH(CONH 2)-]. It is a non
