“…Studies on the use of mechanical activation on ultramafic rocks are constantly expanding. They have focused on comparing individual mineral (e.g., olivine or serpentine) [36,43] responses to the grinding energy input [44,45] and milling instruments (e.g., planetary mills, vibration mills, attrition mills, or tumbling mills) [34,40], as well as milling atmosphere (e.g., N 2 , CO 2 or air) [46], solutions (e.g., water, alcohol or acid) [43,47], and temperatures [48].…”

Recently, integrated mineral carbonation for CO 2 sequestration has received significant attention due to the high potential for commercialization towards mitigating climate change. This review compiles the work conducted by various researchers over the last few years on integrated mineral carbonation processes in the mining industry, which use ultramafic mine wastes as feedstock for mineral carbonation. Here, we introduce the basic concepts of mineral carbonation including a brief description of the process routes and pre-treatment techniques. We discuss the scope of integrated mineral carbonation process application, and critically review the integrated mineral carbonation process in the mining industry including modified passive carbonation techniques in tailing storage facilities, and ex-situ carbonation routes using fresh tailings. The focus of the discussions is the role of reaction condition on the carbonation efficiency of mine waste with various mineralogical compositions, and the benefits and drawbacks of each integrated mineral carbonation process. All discussions lead to suggestions for the technological improvement of integrated mineral carbonation. Finally, we review the techno-economic assessments on existing integrated mineral carbonation technologies. Research to date indicates that value-added by-products will play an important role in the commercialization of an integrated mineral carbonation process.

“…The increasing fuel consumption results in the high level of CO 2 in the atmosphere [1,2]. It is also widely accepted that the emitted CO 2 gas is the main reason for global climate change, which causes many natural disasters: such as flood, droughts, hurricanes, wide spread melting of ice and snow.…”

Corrosion behavior of low‐alloy steel used for pipeline at vapor‐saturated CO₂ and CO₂‐saturated brine conditions

Immersion experiment was carried out to investigate the CO 2 corrosion behavior of low-alloy steel used for pipeline at vapor-saturated CO 2 and CO 2 -saturated brine conditions by revealing microstructure, corrosion rate, corrosion phases, surface/cross-section morphology, and elements distribution. The results demonstrate that mass losses at both conditions are approximately linear to corrosion time with log scale, and the corrosion rate at vaporsaturated CO 2 condition is greatly lower than that at CO 2 -saturated brine condition. The main corrosion phases consisting of inner layer and outer layer are Cr-rich compounds and FeCO 3 crystals, respectively. Corrosion products on the coupon surface produced at vapor-saturated CO 2 condition are formed locally, while the ones produced at CO 2 -saturated brine condition deposit on the coupons surface homogeneously. That distinction is caused by the difference of formation process of corrosive solution. According to the experimental results, corrosion mechanisms of low-alloy steel at both conditions are discussed to illustrate CO 2 corrosion behavior.
