“…From the view point of process modification, two-stage carbonation processes (indirect carbonation) have also been investigated in recent years to optimize the efficiency of the dissolution and carbonation processes, as well as to achieve a pure precipitate product for specific industrial applications (Eloneva et al, 2008a, b;Kodama et al, 2008;Teir et al, 2009). Kodama et al (2008) developed a process using the pH-swing of a weak base -strong acid solution, with the finest particle size (< 63 μm) at 80°C, in which the maximum calcium extraction yield and carbonation conversion achieved were 60% and 70%, respectively.…”

The results indicate that a maximum conversion of 86% was achieved under a CO 2 concentration of 10% vol.…”

CO 2 capture, utilization, and storage (CCUS) is a promising technology wherein CO 2 is captured and stored in solid form for further utilization instead of being released into the atmosphere in high concentrations. Under this framework, a new process called accelerated carbonation has been widely researched and developed. In this process, alkaline materials are reacted with high-purity CO 2 in the presence of moisture to accelerate the reaction to a timescale of a few minutes or hours. The feedstock for accelerated carbonation includes natural silicate-minerals (e.g., wollastonite, serpentine, and olivine) and industrial residues (e.g., steelmaking slag, municipal solid waste incinerator (MSWI) ash, and air pollution control (APC) residues). This research article focuses on carbonation technologies that use industrial alkaline wastes, such as steelmaking slags and metalworking wastewater. The carbonation of alkaline solid waste has been shown to be an effective way to capture CO 2 and to eliminate the contents of Ca(OH) 2 in solid residues, thus improving the durability of concrete blended with the carbonated residues. However, the operating conditions must be further studied for both the economic viability of the technology and the optimal conditions for CO 2 reaction.

“…A method for the conversion of serpentine (Mg 3 Si 2 O 5 (OH) 4 ) into hydromagnesite has been investigated [26] as a way of trapping carbon dioxide and preventing its accumulation in the atmosphere. The process involves production of magnesium chloride from serpentine through the following reaction.…”

Naturally occurring mixtures of hydromagnesite and huntite are important industrial minerals. Their endothermic decomposition over a specific temperature range, releasing water and carbon dioxide, has lead to such mixtures being successfully used as fire retardants, often replacing aluminium hydroxide or magnesium hydroxide. The current understanding of the structure and thermal decomposition mechanism of both minerals and their combination in natural mixtures is reviewed. The crystalline structure of both minerals has been fully characterised. The thermal decomposition of huntite has been characterised and is relatively simple. However, the thermal decomposition mechanism of hydromagnesite is sensitive to many factors including rate of heating and the composition of the atmosphere. The partial pressure of carbon dioxide significantly affects the decomposition mechanism of hydromagnesite causing magnesium carbonate to crystallise and decompose at a higher temperature instead of decomposing directly to magnesium oxide.Keywords: hydromagnesite, huntite, fire, flame, retardant, mineral This review critically examines the sometimes conflicting reports in the published literature. It draws together current knowledge of the structure and thermal decomposition of hydromagnesite and huntite, in order to provide an insight into the thermal behaviour of mixtures of these minerals and to optimise their selection and applications. Industrial use of Mineral Fillers as Fire Retardant AdditivesThe largest group of mineral fire retardants are metal hydroxides. Their endothermic decomposition and associated release of inert gasses or water vapour, above the processing temperature but below the thermal decomposition temperature of polymers suppresses the ignition, while the accumulation of a solid inert residue on the surface of the burning polymer reduces the heat release rate. Aluminium hydroxide (ATH) and magnesium hydroxide are the most widely used [1]. Globally aluminium hydroxide is the highest tonnage fire retardant [2,3]. It decomposes according to the following reaction:The endothermic loss of water resulting from the thermal decomposition of ATH has been variously reported [3][4][5] between 1170 and 1300 Jg Magnesium hydroxide is used less widely than ATH. It decomposes through a similar endothermic mechanism to ATH, giving off water. Mg(OH) 2(s) → MgO (s) + H 2 O (g)The endotherm for this reaction is quoted at values between 1244 to 1450 Jg -1 by various authors [3,[5][6][7]. It starts to decompose at about 300 -330°C giving off water [5]. L.A. Hollingbery, T.R. Hull / Thermochimica Acta 509 (2010) 1-112 Although ATH and magnesium hydroxide are the most well known mineral fire retardants, Rothon [5] has identified a number of minerals (Table 1) that could be of potential benefit in polymers. Each decomposes endothermically with the evolution of either carbon dioxide, water or both. Of these minerals, hydromagnesite is the one that has probably seen most commercial interest. Hydromagnesite is naturally occurring...

“…The theoretical consideration of CCUM is based on the so-called "accelerated carbonation" process, whereby the gaseous CO 2 is reacted with alkalineearth metal-oxide (e.g., CaO and MgO) and converted into carbonate precipitates in the presence of aqueous environments. Appropriate feedstock sources for carbonation reaction include (1) natural ores such as serpentine and wollastonite and (2) alkaline solid wastes such as iron-and steelmaking slag and municipal solid waste incineration fly ash (MSWI-FA) (Eloneva et al, 2012;Teir et al, 2009;Huntzinger et al, 2009;Renforth et al, 2011;Sanna et al, 2012a;Nduagu et al, 2013;Olajire, 2013;Said et al, 2013;Pan et al, 2014). However, accelerated carbonation using natural ores creates its own environmental legacy because of the massive mineral requirements and associated scale of mining (Gerdemann et al, 2007).…”

Carbon dioxide (CO 2 ) emission reduction in industry should be a portfolio option; for example, the carbon capture and utilization by mineralization (CCUM) process is a feasible and proven technology where both CO 2 capture and alkaline waste treatment occur simultaneously through an integrated approach. In this study, the challengeable barriers and significant breakthroughs of CCUM via ex-situ carbonation were reviewed from both theoretical and practical perspectives. Recent progress on the performance of various carbonation processes for different types of alkaline solid wastes was also evaluated based on CO 2 capture capacity and carbonation efficiency. Moreover, several process intensification concepts such as reactor integration and co-utilization with wastewater or brine solution were reviewed and summarized. In addition, the utilization of carbonated products from CCUM as green materials including cement, aggregate and precipitate calcium carbonate were investigated. Furthermore, the current status of worldwide CCUM demonstration projects within the ironand steelmaking industries was illustrated. The energy consumption and cost analyses of CCUM were also evaluated.
