## 1 Introduction  
In a 1914 U.S. Geological Survey Bulletin, [PERSON] et al. [1] presented a detailed study of the minerology and chemistry of the phosphates mined in Florida, specifically Polk and Hillsborough counties of Central Florida. From this report, it was understood that the most uneconomical ingredient in the phosphate mineral matrix was the calcium-magnesium mineral CaMg(CO\({}_{3}\))\({}_{2}\), also known as earth-abundant \"domomite\", with a purity of at least 60% occurring in combination with sand (Silica or quartz \(\sim\)30%). The mining industry routinely terminates their mining process, when they encounter the dolomites or \"dolostones\", which are the major source of magnesium and are not favorable for phosphate fertilizer processing. The gypsum (CaSO\({}_{4}\):2H\({}_{2}\)O) stack is a potential US-EPA sustainability concern for the precipitation of the CO\({}_{2}\) reaction on limestones (calcium carbonate or CaCO\({}_{3}\)) or dolostones [CaMg(CO\({}_{3}\))\({}_{2}\)] during the geological sequestration processes, as demonstrated by [PERSON] et al. [2]. The late Professor of Mineralogy and Geology at Amherst College, [PERSON], published an e-book, \"Field Book of Common Rocks and Minerals\" [3], in which he discusses systematic approaches to identifying minerals and rocks using their physical and chemical properties, including the composition of minerals, and their classifications based on metals. The phenomenon of metamorphism in rocks and minerals have been widely analyzed and discussed by [PERSON] and [PERSON] [4]. The dolomites are not only difficult to remove from the gangue (phosphatic minerals) but also pose \"environmental sustainability\" issues due to their deposition in clay settling ponds around these counties. The magnitude of this problem is considered to be multifold if the future mining processes continue growing to other counties such as Manatee, Hardee, and DeSoto in the State of Florida. The problem of dolomite sedimentation (or stockpiling) in mining plants or clay settling ponds is unavoidable, if there is a depletion of mostly wanted \"overburden\" soil or economic phosphate ones which are the main source of the phosphorous and phosphorites for the fertilizer industry. The presence of the most troublesome magnesium oxide (MgO)-containing dolomites are a major hindrance in the manufacturing of \"phosphoric acid\" for diammonium phosphate (DAP) fertilizer production. The high magnesium content increases the sulfuric acid consumption, and, therefore, causes a lower production rate and yield of phosphoric acid [5; 6]. All of these consequences could be eliminated by a process that utilized the wasted geological resource, dolomite. High-temperature thermochemical energy storage utilizes reversible reactions that store energy in the chemical potential of the system. This type of energy storage process is thought to be critical for the on-demand energy production and penetration of concentrated solar power (CSP) into the grid. Current storage systems rely on molten salts, which have an operating temperature limit of 550 \({}^{\circ}\)C and, therefore, the CSP systems operate at that temperature. However, the CSP plants do have the potential to operate at higher temperature (\(>\)600 \({}^{\circ}\)C) if an alternative to molten salt is found [7]. A recent publication by [PERSON] et al. [8] studied the characterization of surface carbonates obtained from various regions of the Qatar peninsula and have shown promising potential for applications in CO\({}_{2}\) capture and thermochemical energy storage. According to this report, dolomites have higher performance in terms of CO\({}_{2}\) sorption and storage capacity when compared to calcite, CaCO\({}_{3}\)[9; 10; 11]. In a long-term cyclic stability study, up to 27% thermal energy storage was demonstrated by [PERSON] et al. in a groundwater aquifer, which was plausibly due to the presence of minerals (dolomites) [12]. Another vital use of dolomite in producing a most wanted chemical, magnesium sulfate heptahydrate [MgSO\({}_{4}\).
