The effects of cracks on the movement of Ca+2 within gold refining residue [PDF]

, 1997
Gold refining residue is alkaline (pH> 9), saline (EC1:5: 800- 1100 mS/m) and sodic (ESP>60) (Ho et al., 1998). These chemical properties have a detrimental effect on residue physical properties (hydraulic conductivity, bulk density, porosity).

An Elasto–Plastic Hydro–Mechanical Model for Analyzing the Swelling Behavior of Heterogeneous Clay–Sulfate Rocks

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Swelling of clay‐sulfate rocks is a concern in geotechnical engineering that can damage infrastructure. In the historic town of Staufen in southwest Germany, geothermal drilling into a swellable anhydrite‐bearing clay formation resulted in water inflow and subsequent swelling, triggering ground heave and damage to more than 250 houses.
