“…Since almost three decades ago when mineral carbonation was introduced and subsequently studied as a process to sequester CO 2 [4], much research have been carried out in laboratory and pilot scales [1][2][3][4][5][6][7] focusing on selection, preparation, and activation of feedstock as well as proposing various approaches and optimizing process parameters. However, only a limited number of studies have been conducted with regard to the applications of by-products mainly generated from indirect (two-stage) mineral carbonation process [8][9][10][11][12][13].…”

In this experimental work we synthesized, characterized, and investigated the reactivity of silica‐enriched residue materials produced from low pressure, low temperature dissolution applicable to a two stage mineral carbonation process. XRF and XRD analysis indicated that 66 wt % of silica‐enriched residue (SER) produced from dissolution of heat activated lizardite comprised amorphous silica. We also treated SER with nitric acid to produce amorphous acid treated silica‐enriched residue (ATSER) with over 88 wt % silica. Dissolving these synthesized materials in highly alkaline solution with pH similar to cement paste pore solution for 28 days showed that all synthesized materials displayed some level of Si solubility. ATSER showed the most rapid rate of Si extraction, higher than silica fume (a commercial pozzolanic cement substitute), followed by silica‐enriched residue (SER) which had a faster rate of Si extraction compared with Portland cement as a standard. © 2018 American Institute of Chemical Engineers Environ Prog, 38:e13066, 2019

“…Their research and technical facilities are centred at the University of Newcastle, Australia. MCi's suite of projects includes fundamental theoretical and laboratory research [66,[95][96][97][98][99][100] as well as one of the world's first mineral carbonation pilot plant facilities [101,102]. MCi's project has primarily been studying the carbonation of serpentine, which as mentioned above is an abundant mineral in New South Wales (NSW), Australia and globally [102].…”

Carbon capture, utilisation and storage (CCUS) via mineral carbonation is an effective method for long-term storage of carbon dioxide and combating climate change. Implemented at a large-scale, it provides a viable solution to harvesting and storing the modern crisis of GHGs emissions. To date, technological and economic barriers have inhibited broad-scale utilisation of mineral carbonation at industrial scales. This paper outlines the mineral carbonation process; discusses drivers and barriers of mineral carbonation deployment in Australian mining; and, finally, proposes a unique approach to commercially viable CCUS within the Australian mining industry by integrating mine waste management with mine site rehabilitation, and leveraging relationships with local coal-fired power station. This paper discusses using alkaline mine and coal-fired power station waste (fly ash, red mud, and ultramafic mine tailings, i.e., nickel, diamond, PGE (platinum group elements), and legacy asbestos mine tailings) as the feedstock for CCUS to produce environmentally benign materials, which can be used in mine reclamation. Geographical proximity of mining operations, mining waste storage facilities and coal-fired power stations in Australia are identified; and possible synergies between them are discussed. This paper demonstrates that large-scale alkaline waste production and mine site reclamation can become integrated to mechanise CCUS. Furthermore, financial liabilities associated with such waste management and site reclamation could overcome many of the current economic setbacks of retrofitting CCUS in the mining industry. An improved approach to commercially viable climate change mitigation strategies available to the mining industry is reviewed in this paper.

“…Reduction in greenhouse gases deemed necessary as their concentration rise sharply from 280 ppm to 419 ppm . Mineral carbonation [1][2][3][4][5][6][7][8][9][10][11][12][13][14], geological storage, oceanic storage and biomineralization as well as chemicals production especially fuels are basic technologies in use. Mineral carbonation is a Short Communication permanent fixation of CO2.…”

In education pedagogy, its necessary to prioritize tasks and jobs. Learn operating the reactor or required apparatus but most important first. Regarding measuring techniques (PSD measurement, pH measurement, XRD, SEM/EDS), learn more basic and fundamental techniques first followed by complimentary techniques. Regarding mineral carbonation, operation of reactor is a basic need followed by particle size measurement using Malvern Mastersizer and powders samples XRD analysis and identifying the phases and verifying those phases through TGA analysis. This article illustrates author personal research of 4 initial 4 months duration. Month wise progress is presented in this article in an interesting way.
