“…Malachite is a common copper oxide mineral that primarily consists of CuCO3 and Cu(OH)2, which should be sufficiently exploited to ensure the long-term viability of copper resources (Cecile et al, 1981;. The available copper sulfide resources are depleting as copper consumption and demand rise (Chen et al, 2014;.…”

In this study, ammonium phosphate ((NH4)3PO4) was employed to realize improvement by modifying the physical characteristics of the malachite surface, ensuring sustainable flotation throughout the flotation operations, and enhancing the flotation process to be more stable. Furthermore, various techniques, including X−ray photoelectron spectroscopy, were intensely used to investigate the configuration and physico-chemical surface characteristics through micro-flotation experiments, contact angle and zeta potential measurements, and XRD, ToF−SIMS, EPMA, and FTIR spectrum analyses. The FTIR findings showed that new characteristic peaks of −C(=S)−N.H. groups formed and adsorbed on the surfaces of malachite at 1636 cm-1. The −CH2 groups throughout the flotation process, further promoted the attachment of the CH3 ligand to the Cu2+ ion, and the XPS analysis confirmed this. Consequently, it can be concluded that (NH4)3PO4 played a substantial part in the improved recovery rate, as demonstrated and confirmed by the methods carried out in this study. Thus, it was used to modify the physical properties surface before adding Na2S to efficiently enhance malachite floatability and reduce the loss rate of malachite. Regarding the alterations in the physical characteristics which occurred to the malachite surface, and as a consequence of increasing the recovery results of flotation, the malachite sample treated initially with (NH4)3PO4 exhibited micro flotation results with a considerably greater flotation recovery than malachite treated initially with only Na2S ions.

A sensitive and efficient method for the determination of acidity constants of salicylaldoxime (SALO) (2-hydroxybenzaldehyde oxime), using both Raman spectroscopic and potentiometric methods, at 30 Â°C in 50 (wt/wt) of ethanol-water mixture and at the constant ionic strength I = 0.1 M is proposed. The effect of pH on the Raman spectra has also been studied. The Raman spectroscopic technique allows the identification of compounds in different molecular and molecular ionic structures. The limit of detection (LOD) was determined to be 0.05 mol dm-3 for SALO by means of Raman peak area. Â© 2010 John Wiley & Sons, Ltd
