The unique properties of ionic liquids (ILs) drive the growing number of novel applications in different industries. The main features of ILs are high thermal stability, recyclability, low flash point, and low vapor pressure. This study investigated pure chalcopyrite dissolution in the presence of the ionic liquid 1-butyl-3-methylimidazolium hydrogen sulfate, [BMIm]HSO4, and a bromide-like complexing agent. The proposed system was compared with acid leaching in sulfate media with the addition of chloride and bromide ions. The results demonstrated that the use of ionic liquid and bromide ions improved the chalcopyrite leaching performance. The best operational conditions were at a temperature of 90 °C, with an ionic liquid concentration of 20% and 100 g/L of bromide.

Carbon Core

In this paper, we report a simple solid-state method for fabricating cobalt-oxide–carbon core-shell nanostructures. With this technique, various forms of nanocarbons such as nanotubes, polyhedrons and onions can be generated via pyrolyzing cobalt–complex xerogels at 150 ~ 340°C. The thus-formed nanocarbons can be protected by cobalt-oxide matrix up to 1000°C in air atmosphere. Cobalt-oxide shelled or unshelled nanocarbons can be controlled by choosing a suitable complexing agent for the xerogel precursors. In particular, glycine has been proven to be a good complexing agent for low-temperature formation of unshelled nanocarbons and high-temperature generation of shelled nanocarbons.
