NI(II)-HYDROXOSULFATOAMMINO COMPLEXES SEPARATED BY DISSOLVED-AIR FLOTATION

The paper studies the composition and the structure of the chemical sp ecies (sublates) isolated in scum, in the process of Ni(II) ion(collig end) separation by iono-molecular flotation from diluted solutions usi ng laurylamine (LA) as collector. The chemical analysis data correlate d with molecular electrical conductivity measurements, electronic and vibrational spectra, TD analysis and X Rays spectra of sublates establ ish the coordinative nature of collector-colligend interaction The Ni( II) recovery as NiO can be done by the calcination of sublates at 500 degrees, 1/2 hour.
