In this article we report use of novel starch-based functional hydrogels as Cu2+ ions sorbents. Starch was functionalized by acid hydrolysis and/or oxidized by nitrogen oxides to generate carboxylic groups at C-6. Sorption of Cu2+ ions was studied as a function of hydrogel structure and environmental factors.

The CIL process The carbon-in-leach (CIL) process, illustrated in Figure 3 is a variation of the CIP process. In this process carbon is added directly to the leach circuit so that the leaching and adsorption processes proceed simultaneously. Capital cost is reduced, as only one set of agitators for both leaching and

 · An Ag–TiO2 photocatalyst with 3.5 atom % silver content, synthesized by a single step sol–gel method, possessed silver nanoparticles (AgNPs; 1–5 nm) on the TiO2 surface, but owing to the nonplasmonic nature of AgNPs and the wide band gap of TiO2, this material exhibited poor activity in a photocatalytic degradation reaction. However, this least active Ag–TiO2 catalyst showed a sudden ...

 · Different to cyanidation, the gold halide leaching in SCE2 does not have in situ gold recovery, but gold recovery is conducted after S/L separation by adsorption to silica, with reported recovery of as high as 99.98% (Lalancette et al. 2015b). According to these values, the simulation predicts 87.3% gold recovery.
