The reactions of oxide and sulfide minerals with acids are among the most straight-forward of chemical reactions. Despite this, there are still aspects which are not fully understood or explained. The rate of dissolution of these minerals is remarkable, in the sense...

The kinetics of the dissolution of silicates, aluminosilicates and quartz is described by a novel theory of dissolu- tion. The experimental data for the rate of dissolution of these minerals shows a remarkable pattern: for many of these minerals, the order of reaction...

A new theory for the description of the kinetics of non-oxidative dissolution reactions is proposed. The theory ac- counts for the breaking of bonds between the constituents of a solid, which results in charged species, and the simultaneous transfer of these charged...

Pyrite is an abundant mineral, and its dissolution is important in the formation of acid mine drainage and the extraction of metals. It has also been considered as a candidate material for electrochemical solar cells. We studied the anodic processes on pyrite in...
