Zn(II) and Cu(II) Uptake from Acid Solutions with Microcapsules Containing a Non-Specific Alkyl Phosphonic Extractant
(SOCIEDAD CHILENA DE QUIMICA, 2005-12)
It is studied the uptake of Zn(II) and Cu(II) from acid aqueous solutions using microcapsules containing 2-ethylhexylphosphonic acid mono-2-ethylhexyl ester, a non-specific extractant, as an alternative method for metals ...
Recuperação de metais a partir da lama vermelha
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2015-08-25)
This paper describes an integrated process for recovering aluminum, iron, titanium, sodium and silica from red mud through a hydrometallurgical treatment sequence. The disposal of red mud, which is the largest waste produced ...
