The solubility of carbonates … • In addition to alkali metal impurities, coal often contains substantial amounts of alkaline earth metals in the form of carbonate minerals such as calcite (CaC03) and dolomite (CaCC>3 gC03). The smaller size and the charge density increases the hydration energy of the beryllium sulphate leading to more solubility. However, carbonate of lithium, when heated, decomposes to form lithium oxide. Performance & security by Cloudflare, Please complete the security check to access.
