%X This study investigated the conversion of monohydrocalcite (MHC)</span></span><span><span><span style=\"font-family:&quot;\"> </span></span></span><span><span><span style=\"font-family:&quot;\">to anhydrous
calcium carbonate. The primary material, MHC, was produced from waste brines
containing Ca and Mg ions, reacted with sodium carbonate, which may serve in
the carbon capture and mineralisation approach. Two different approaches to the
conversion were studied: </span></span></span><span><span><span style=\"font-family:&quot;\">1</span></span></span><span><span><span style=\"font-family:&quot;\">) the conversion of MHC conversion to anhydrous calcium carbonates in air
(under ambient conditions)</span></span></span><span><span><span style=\"font-family:&quot;\">;</span></span></span><span><span><span style=\"font-family:&quot;\"> </span></span></span><span><span><span style=\"font-family:&quot;\">2</span></span></span><span><span><span style=\"font-family:&quot;\">) the identification of conversion conditions which could be adapted for
potential industrial application. The former focused on the effects of the
synthesis system conditions of the primary material on the aragonite conversion
process and the resulting aragonite morphology, whereas the latter covered the
factors that accelerate conversion and influence the resulting morphology. The
paper also discusses instances where MHC converts to the more stable polymorph</span></span></span><span><span><span style=\"font-family:&quot;\">, </span></span></span><span><span><span style=\"font-family:&quot;\">calcite.
It was found that conditions leading to the polymorphic and morphological selection
of converted minerals were temperature and humidity dependant.
