Flow, dissolution, and precipitation in dolomite

dissolution of dolomite is a (slow) reaction rate limited process at room temperature [Lund et al., 1973]. The main aim of the current experimental research is to understand the evolution of hydraulic conductivity and flow patterns, caused by concurrent dissolution of dolomite and precipi-tation of calcium carbonate, in porous dolomite rocks. In

Dolomite - an overview | ScienceDirect Topics

Dolomite is a magnesium ore with the general formula MgCO 3 ·CaCO 3. The use of dolomite as a catalyst in biomass gasification has attracted much attention (Xu, Donald, Byambajav, & Ohtsuka, 2010). The chemical composition of dolomite varies from source to source, but it generally contains 30 wt.% CaO, 21 wt.% MgO, and 45 wt.% CO 2.
