Effect of dissolved components of malachite and calcite on surface properties and flotation behavior

Zhihao Shen et al.

Summary: The study investigated the effect of dissolved components derived from malachite and calcite on the flotation behavior and surface characteristics of both minerals. It was found that the presence of calcite supernatant decreased the recovery of malachite, while the malachite supernatant increased the recovery of calcite. Various tests demonstrated that the Ca species in the calcite supernatant hindered the interaction of Na2S with malachite, resulting in insufficient adsorption of NaIX on the surface of malachite. On the other hand, the Cu species in the malachite supernatant provided active sites for the adsorption of Na2S and NaIX onto the calcite surface.

Speciation of Hexavalent Chromium in Aqueous Solutions Using a Magnetic Silica-Coated Amino-Modified Glycidyl Methacrylate Polymer Nanocomposite

Ljiljana Surucic et al.

Summary: A new magnetic amino-functionalized polymeric sorbent was synthesized and used for the separation of Cr(VI) oxyanions from aqueous solutions. The sorption process was found to be controlled by both intraparticle diffusion and liquid film diffusion. The equilibrium results showed that the sorption process is best described by the Freundlich model, with a maximum sorption capacity of 64 mg/g. Quantum chemical modeling revealed that the sorption sites on the sorbent surface are fragments with diethylenetriamine and aminopropyl silane groups. XPS spectra demonstrated that the chromium bound to the sorbent in the form of Cr(III), indicating its conversion to a less harmful form on the surface of the sorbent.
