DOI: 10.1016/j.colsurfa.2020.125460
Abstract: Abstract The dissolved components of calcium-bearing gangue minerals that are adsorbed on the surface of magnesite can make it difficult to effectively separate magnesite from dolomite. In this study, ethylene glycol–bis(β–aminoethyl ether)–N,N,N′,N′–tetraacetic acid (EGTA) is… read more here.
