Abstract:There is quite abundant resource of ludwigite ore in Liaoning Province of China. Content of MgO in the slag of pyrometallurgical separation of boron from iron is much higher than that in the ordinary slags. Through the equilibrium partition ratio of sulfur L_S between the metal and the slag in an atmosphere of CO-N₂, the acidic coefficients for B₂O₃ and the basic coefficients for MgO were estimated. The basic formulae were given for the blast furnace-type slag containing B₂O₃ and high MgO.

Key words: basic formula; blast furnace-type slag bearing B₂O₃ and MgO; equilibrium partition ratio of sulfur
