Selective Crystallization and Separation of B in B-Bearing Slag

It reports the selective crystallization and separation of B in B-bearing slag. The competitive crystallization behavior of B, Si, and Mg in B-bearing slag is reported in Sect. 3.1. The study on two-stage separation of olivine and suanite, the selective separation of last precipitated suanite, and the crystalline phase transformation and one-step separation of suanite in molten B-bearing slag are included in Sect. 3.2, 3.3, and 3.4, respectively.
