The K-feldspar mineral is an insoluble potassium resource with a high potassium content and the most extensive and abundant reserves. To address the insufficient supply of soluble potassium fertilizers in China, the application of appropriate processing methods to extract potassium from K-feldspar and transform it into a soluble potassium fertilizer is of great significance. To date, various techniques have been developed to extract potassium from K-feldspar and produce a soluble potassium fertilizer. This review summarizes the main methods, i.e., the hydrothermal, high-temperature pyrolysis, microbial decomposition, and low-temperature methods, for potassium extraction from K-feldspar. The mechanisms, efficiencies, impact parameters, and research progress of each potassium extraction method are comprehensively discussed. This study also compares the merits and drawbacks of the individual methods in terms of potassium extraction efficiency and practical operating conditions. The species of additives, reaction temperature, reaction time, particle size of K-feldspar, and dosage of additives significantly affected the potassium extraction efficiency. Moreover, the combination of different methods was very effective in improving the potassium extraction efficiency. This review elaborates the research prospects and potential strategies for the efficient utilization of the K-feldspar mineral as a fertilizer resource.

“…(1) Silicate minerals are the most abundant class of minerals in the Earth's crust and are composed primarily of silicon (Si) and oxygen (O) atoms combined with various cations (positively charged ions), such as aluminum (Al), iron (Fe), magnesium (Mg), and others. Silicate minerals include feldspars, quartz, micas, amphiboles, and pyroxenes [67]. (2) Carbonate minerals are characterized by the carbonate ion (CO 3 2− ) as a fundamental building block.…”

The mining industry generates vast quantities of mine tailings on an annual basis. However, due to their limited economic value, a significant portion of these tailings are deposited close to mining sites, often underwater. The principal environmental apprehensions associated with mine tailings revolve around their elevated levels of heavy metals and sulfidic minerals. The oxidation of these sulfidic minerals can lead to the formation of acid mine drainage, which in turn releases heavy metals into nearby water systems. The effective management of tailing dams requires substantial financial investments for their construction and meticulous control. Consequently, a pressing need exists for stable, sustainable, and economically viable management approaches. One promising method for addressing mine tailings is through alkali activation, a technique that serves as a stabilization process. This approach yields robust, concrete-like structures by utilizing raw materials abundant in aluminum and silicon, which conveniently constitute the primary components of mining residues. This comprehensive review outlines the research on utilizing alkali activation for mine tailings. It delves into the reactivity and chemical attributes of diverse minerals. Numerous mine tailings exhibit an inadequate level of reactivity under alkaline conditions, so various pre-treatment methodologies and their impacts on mineralogy are meticulously explored.

“…The population (88%) in Kanchanadit District engaged in agriculture, fishing and small agricultural industry. The function of minerals studied (K, Ca, Mg, Na and Mn) are related to the composition and various roles in blood cockles, such as calcium is the main substance in the formation of shells and muscle contraction [42], magnesium and manganese play roles in shell building [43] and potassium and sodium control muscle and nervous function and balance water in the cells [44]. It is related to Boonyuen et al [45] which found that blood cockle shells consisted of calcium carbonate (CaCO 3 ) (95-97%) as calcite form in the prismatic layer, which was the strongest layer.…”

Bandon Bay is a very fertile bay for coastal aquaculture, especially for blood cockles (Anadara granosa). Its structural pattern supports the flow of nutrients which directly sent from many rivers resulted the high production capacity of blood cockle at the top level in the country. Besides organic compounds present in sediment, inorganic substances are essential for growth, survival and shell development of blood cockles. A comparative study of minerals and oxide compounds which accumulated in the sediments at eight stations around the cockle culture area was conducted. These stations are located along the estuaries at Tha Thong, Tha Chang, Phum Riang, and Tapi. The proportion of oxide compounds were determinedusing X-Ray Fluorescence (XRF) technique and minerals were analyzed by Atomic Absorption Spectroscopy (AAS). Results showed that sediment characteristics, oxide composition and the amount of minerals among the stations are different from each other. The sediments of the eastern and the western coasts were characterized as crumble clay and muddy sand, respectively. Twelve types of oxide compounds, namely SiO2, Al2O3, Fe2O3, K2O, Cl, MgO, Na2O, SO3, CaO, TiO2, MnO, P2O5 were found in various quantities, with SiO2, Al2O3, and Fe2O3 were the fundamental minerals ranging from 85.64–90.82%. Tha Thong estuary in the east coast showed highly significant quantities (P<0.05) of potassium, calcium and manganese compared to the other estuaries.
