摘要

The olivine crystals and borate containing slag were effectively separated from the CaO-SiO_2-B_2O_3-MgO-Al_2O_3 system at an optimum precipitating temperature of olivine by utilizing super-gravity. The borate containing slag melt went through the filter, whereas the olivine crystals with a larger size of 300 μm-2 500 μm were intercepted by the filter. Consequently, after super-gravity separation with G=900 at 1 463 K for 5 minutes, the mass fraction of B_2O_3 in separated borate containing slag was 30.17 wt%, while that of the separated olivine was only 0.009 wt%, and the recovery ratio of boron in separated borate containing slag thus was up to 99.97%.
