Ngemuva kokukhishwa kwe-ultrasonic kanye nokuhlukaniswa kwe-centrifuge kanye nemvula, amasampula ensimbi yensimbi ahlungwa ngekholomu ye-IC-RP, ikholomu ye-IC-Na kanye ne-0.22 um microporous filtration membrane ngokulandelanayo.Kusetshenziswa i-CIC-D120 ion chromatograph, ikholomu ye-anion ye-SH-AC-3, 3.6 mM Na2CO3+4.5 mM NaHCO3 eluent kanye nendlela ye-bipolar pulse conductance, ngaphansi kwezimo ezinconyiwe zechromatographic, i-chromatogram imi kanje.
Imikhawulo yokuthola ye-F- ne-Cl- ingu-2.1 ug/g no-3.5 ug/g.Ukutholwa kwe-F- kanye ne-Cl- kungu-96% -104%.Ingasetshenziselwa ukuhlaziya insimbi yemvelo yensimbi, i-iron ore concentrate namanye amasampula.
