The optimum roasting conditions were: calcination temperature, 450°C; calcination time, 120 min; molar ratio of reactants, 2 : 1; granularity <80 µm. The … WebOct 31, 2024 · Carbonate Ores. Carbonate is basically composed of a salt of carbonic acid having a formula of H 2 C O 3. Moderately powerful bases include carbonates. Because the carbonate anion can accept a hydrogen ion from water, aqueous solutions are basic. It interacts with acids to produce water, gaseous carbon dioxide, and metal salts. the landing at herrington harbour north
