“…Simulation results could be sensitive to the choice of secondary minerals. However, almost all possibilities of secondary carbonate and clay minerals are covered in the simulations, which are based on previous studies of modelling (Xu et al, 2005(Xu et al, , 2006Gaus et al, 2005;White et al, 2005), laboratory experiments (Wolf et al, 2004;Chen et al, 2006), and field observations (Pearce et al, 1996;Watson et al, 2004;Moore et al, 2005;Worden 2006). …”

The geological storage of CO 2 in deep saline formations is increasing seen as a viable strategy to reduce the release of greenhouse gases to the atmosphere. There are numerous sedimentary basins in China, in which a number of suitable CO 2 geologic reservoirs are potentially available. To identify the multi-phase processes, geochemical changes and mineral alteration, and CO 2 trapping mechanisms after CO 2 injection, reactive geochemical transport simulations using a simple 2D model were performed. Mineralogical composition and water chemistry from a deep saline formation of Songliao Basin were used. Results indicate that different storage forms of CO 2 vary with time. In the CO 2 injection period, a large amount of CO 2 remains as a free supercritical phase (gas trapping), and the amount dissolved in the formation water (solubility trapping) gradually increases. Later, gas trapping decreases, solubility trapping increases significantly due to migration and diffusion of the CO 2 plume, and the amount trapped by carbonate minerals increases gradually with time. The residual CO 2 gas keeps dissolving into groundwater and precipitating carbonate minerals. For the Songliao Basin sandstone, variations in the reaction rate and abundance of chlorite, and plagioclase composition affect significantly the estimates of mineral alteration and CO 2 storage in different trapping mechanisms. The effect of vertical permeability and residual gas saturation on the 2 overall storage is smaller compared to the geochemical factors. However, they can affect the spatial distribution of the injected CO 2 in the formations. The CO 2 mineral trapping capacity could be in the order of ten kilogram per cubic meter medium for the Songliao Basin sandstone, and may be higher depending on the composition of primary aluminosilicate minerals especially the content of Ca, Mg, and Fe.

“…These two effects are mutually beneficial, since as more magnesium precipitates as carbonate, more magnesium can leach from the silicate, propagating the reaction. Increasing the temperature also increases Henry's constant for the dissolution of CO2 in the water, which can have a negative impact on the carbonation [20], but this was not observed here. O'Connor et al [23] found that these counteracting temperature effects lead to an optimal olivine carbonation temperature of 185 °C.…”

“…The use of additives aims at enhancing the dissolution of magnesium, the dissociation of carbonic acid, and/or the precipitation of magnesium carbonate. Sodium chloride (NaCl) and sodium bicarbonate (NaHCO3) were tested as carbonation enhancing additives as suggested by Chen et al [20].…”

“…Chen et al [20] state that adding sodium bicarbonate reduces the concentration of magnesium ions required to exceed the solubility product for magnesium carbonate and, thus, promotes the precipitation of magnesite. They explain that this is because in solutions with a large amount of NaHCO3, the concentration of CO3 2− is inversely proportional to CO2 pressure and proportional to the square of the concentration of NaHCO3.…”

Abstract:In this work, we explore a novel mineral processing approach using carbon dioxide to promote mineral alterations that lead to improved extractability of nickel from olivine ((Mg,Fe)2SiO4). The precept is that by altering the morphology and the mineralogy of the ore via mineral carbonation, the comminution requirements and the acid consumption during hydrometallurgical processing can be reduced. Furthermore, carbonation pre-treatment can lead to mineral liberation and concentration of metals in physically separable phases. In a first processing step, olivine is fully carbonated at high CO2 partial pressures (35 bar) and optimal temperature (200 °C) with the addition of pH buffering agents. This leads to a powdery product containing high carbonate content. The main products of the carbonation OPEN ACCESSMetals 2015, 5 1621 reaction include quasi-amorphous colloidal silica, chromium-rich metallic particles, and ferro-magnesite ((Mg1−x,Fex)CO3). Carbonated olivine was subsequently leached using an array of inorganic and organic acids to test their leaching efficiency. Compared to leaching from untreated olivine, the percentage of nickel extracted from carbonated olivine by acid leaching was significantly increased. It is anticipated that the mineral carbonation pre-treatment approach may also be applicable to other ultrabasic and lateritic ores.

“…Many authors have mentioned basalts in general as potential host rocks for in-situ mineral carbonation (McGrail et al, 2006;Goldberg et al, 2008;Matter et al, 2009;Rosenbauer et al, 2012); numerous aqueous phase studies for pure minerals and CO 2 have been conducted (Wogelius and Walther, 1991;Guthrie et al, 2001;Oelkers and Gislason, 2001;Gerdemann et al, 2003;Gíslason and Oelkers, 2003;Bearat et al, 2006;Chen et al, 2006;Krevor and Lackner, 2009); and studies on thermodynamics and kinetics of mineral carbonation have been performed (Königsberger et al, 1999;Marini, 2007;Krupka et al, 2010;Aradóttir et al, 2012;Rosenbauer et al, 2012). Most of the work mentioned above is based on either specific basalts, or some kind of assumed basalt composition that is believed to be typical.…”

With international efforts to limit anthropogenic carbon in the atmosphere, various CO 2 sequestration methods have been studied by various facilities worldwide. Basalt rock in general has been referred to as potential host material for mineral carbonation by various authors, without much regard for compositional variations due to depositional environment, subsequent metamorphism, or hydrothermal alteration. Since mineral carbonation relies on the presence of certain magnesium, calcium, or iron silicates, it is necessary to study the texture, mineralogy, petrology, and geochemistry of specific basalts before implying potential for mineral carbonation. The development of a methodology for the characterization of basalts with respect to their susceptibility for mineral carbonation is proposed to be developed as part of this research. The methodology will be developed based on whole rock data, petrography and microprobe analyses for samples from the Caledonia Mine in Michigan, which is the site for a proposed small-scale demonstration project on mineral carbonation in basalt. Samples from the Keweenaw Peninsula will be used to determine general compositional trends using whole rock data and petrography. Basalts in the Keweenaw Peninsula have been subjected to zeolite and prehnite-pumpellyite facies metamorphism with concurrent native copper deposition. Alteration was likely due to the circulation of CO 2 -rich fluids at slightly elevated temperatures and pressures, which is the process that is attempted to be duplicated by mineral carbonation.4
