Leaching Chalcopyrite with High MnO2 and Chloride Concentrations
Most copper minerals are found as sulfides, with chalcopyrite being the most abundant. However; this ore is refractory to conventional hydrometallurgical methods, so it has been historically exploited through froth flotation, followed by smelting ...

Quantifying susceptibility of marine invertebrate biocomposites to dissolution in reduced pH [PDF]
Ocean acidification threatens many ecologically and economically important marine calcifiers. The increase in shell dissolution under the resulting reduced pH is an important and increasingly recognized threat.

Liquisolid technique for dissolution rate enhancement of a high dose water-insoluble drug (carbamazepine) [PDF]
Different liquisolid formulations of carbamazepine were accomplished by dissolving the drug in the non-toxic hydrophilic liquids, and adsorbing the solution onto the surface of silica.

Dual-barrel conductance micropipet as a new approach to the study of ionic crystal dissolution kinetics [PDF]
A new approach to the study of ionic crystal dissolution kinetics is described, based on the use of a dual-barrel theta conductance micropipet. The solution in the pipet is undersaturated with respect to the crystal of interest, and when the meniscus at ...

Experimental determination of plagioclase dissolution rates as a function of its composition and pH at 22°C. [PDF]
The steady-state, far-from-equilibrium dissolution rates of nine distinct plagioclases ranging in composition from An2 to An89 were measured in mixed flow reactors at 22 ± 2 C and pH from 2 to 11.
