Removal of boron from aqueous solution using cryptocrystalline magnesite

Journal of Water Reuse and Desalination, 2017
The present study aimed to evaluate the efficiency of using cryptocrystalline magnesite to remove boron ions from aqueous systems. Batch experimental protocols were used to evaluate the adsorption capacity of magnesite for boron.

Rheology of magnesite [PDF]

Journal of Geophysical Research: Solid Earth, 2014
AbstractWe deformed two natural magnesite aggregates (grain sizes of 1 versus 100 µm) over a wide range of temperatures (400–1000°C) and strain rates (10−7–10−4/s) in order to determine the deformation mechanisms of magnesite and their respective flow laws.

The dissolution study of a South African magnesium-based material from different sources using a pH-stat [PDF]

, 2011
One of the main steps in the wet flue gas desulphurization (WFGD) process is the dissolution of either magnesite or limestone. Evaluating the magnesite dissolution rate is vital for the design and efficient operation of wet FGD plants.

Mineral reconnaissance at the Highland boundary with special reference to the Loch Lomond and Aberfoyle areas [PDF]

, 1983
Serpentinite bodies at the Highland Boundary in the Loch Lomond and Aberfoyle areas are extensively altered to magnesite-quartz and ferroan-dolomite-quartz rocks. Silicification was probably initiated before conversion to carbonate.
