MDAG Case Study 23
Also, simple oxidation and weathering, followed by larger-volume secondary-mineral precipitation, can force grains from rock surfaces (Jerz and Rimstidt, 2003) and thus increase slaking. Â ...

MDAG Case Study 28
The transient intermediate pH values can tell us much about the complex precipitation-dissolution of minerals during the spatial and temporal migration of ARD through initially ... sand aquifer initially containing calcite. These steps were called “sub-regions†of distinct mineral precipitation-dissolution (Figures 7 to 9, and Table 1), reflecting transient equilibrium conditions (Morin ...
