| Abstract: | Serpentine was preprocessed by ball milling and calcinating processes to destroy its crystal structure and improve its physical and chemical properties. After that, the ore sample was leached by different kinds of inorganic acid. Through the experiment, the optimum operating conditions of the main process are established, that is, the ore sample is ground for 1h by ball mill, calcined at 700 ℃ for 1 h, and then mixed with 3 mol/L H2SO4 and stirred at normal temperature. The solid/liquid ratio is 1∶15. Under the optimum operating conditions, the leaching ratio of magnesium oxide in serpentine is up to 93%. |
