Concurrent grinding is shown to result in a significant increase in magnesite yields for non-heat activated feedstock, prepared such that fines (<20 µm particles) were excluded from the feed. We assert that concurrent grinding may be a suitable technique for the processing of feedstocks such as those containing significant proportions of forsterite and pyroxene, minerals which are unresponsive to thermal activation for use in aqueous mineral carbonation. This study also investigates the effect of different grinding media particle size on reducing the particle size distribution (PSD) of the feed. Optimum ratio of grinding media size to feed particle size, optimum grinding media and slurry concentrations, optimum time for grinding and optimum impeller designs are determined for the system under study. The quantitative effect of grinding media concentration, slurry concentration, pressure and temperature on magnesite yield has been investigated.]]> Wed 10 May 2023 14:51:12 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:20098 −1, to minimise secondary CO₂ emissions generated from the thermal activation of serpentinite. A CO₂ penalty of about 7% yields 0.93 net tonne of available active serpentine per tonne of serpentinite feedstock. The cost for serpentinite heat activation for this practical heating strategy amounts to A$ 1.25 per tonne of available active serpentine.]]> Sat 24 Mar 2018 08:00:07 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30332 Sat 24 Mar 2018 07:31:49 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:43059 Mon 12 Sep 2022 15:12:49 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:35170 Fri 28 Jun 2019 17:14:42 AEST ]]>
