Cu(II) separation from diluted aqueous solutions by flotation with atypical collectors anti and syn 2–hydroxy–3,5–di–tert–butyl–benzaldoxime
The paper is a contribution to the development of the flotation separation area, concerning in the proposal of new atypical collectors (anti and sin 2–hydroxy–3,5–di–tert–butyl–benzaldoxime) for the metallic ions separation from diluted aqueous systems. A case study (R%) was studied and the optimal parameters were established. The insoluble species of Cu(II), isolated by flotation were characterised by physical–chemical methods, for establishing the Cu(II)–collector interaction. The experimental results showed the efficiency of both collectors for Cu(II) removal (%R∼100). This systematic research based on structure–properties–floatability correlation, allow to these atypical collectors to be also tested for other metallic ions.
