Surface Forces Apparatus Measurements of Interactions between Rough and Reactive Calcite Surfaces. [PDF]
Langmuir, 2018 nm-Range forces acting between calcite surfaces in water affect macroscopic properties of carbonate rocks and calcite-based granular materials and are significantly influenced by calcite surface recrystallization. We suggest that the repulsive mechanical

Effect of calcium concentration on calcite flotation from apatite using carbonic gas
REM: International Engineering Journal, 2020 The flotation process currently considered for apatite concentration from the Santa Quitéria phosphate deposit (Brazil), involves bulk flotation of apatite and calcite with anionic collector at pH=10 followed by calcite flotation at pH=5.5, adjusted with

Mg/Ca ratios in freshwater microbial carbonates: Thermodynamic, kinetic and vital effects [PDF]
, 2014 The ratio of magnesium to calcium (Mg/Ca) in carbonate minerals in an abiotic setting is conventionally assumed to be predominantly controlled by (Mg/Ca)solution and a temperature dependant partition coefficient. This temperature dependence suggests that

The influence of normal stress and sliding velocity on the frictional behaviour of calcite at room temperature. Insights from laboratory experiments and microstructural observations [PDF]
, 2016 The presence of calcite in and near faults, as the dominant material, cement, or vein fill, indicates that the mechanical behaviour of carbonate-dominated material likely plays an important role in shallow- and mid-crustal faulting. To better understand

Water Orientation at the Calcite-Water Interface [PDF]
The Journal of Physical Chemistry Letters, 2021 Mineral-water interfaces play an important role in many natural as well as technological fields. Fundamental properties of these interfaces are governed by the presence of the interfacial water and its specific structure at the surface. Calcite is particularly interesting as a dominant rock-forming mineral in the earth's crust.

Effect of Temperature, pH, and Reaction Duration on Microbially Induced Calcite Precipitation
Applied Sciences, 2018 In this study, the amount of calcite precipitate resulting from microbially induced calcite precipitation (MICP) was estimated in order to determine the optimal conditions for precipitation.
