Electromagnetic separation of silicon from metallurgical-grade silicon refined slag during the remelting process

Competitive crystallization, in situ separation and solidification mechanism of Cr-spinel crystal from Cr-bearing slag

“…24 In the last few decades, some outfield enhancement methods, including electromagnetic and microwave, have been introduced in the high-temperature metallurgical process to enhance the separation efficiency of various phases. 25,26 In particular, the supergravity methods and effective separation via high-speed centrifugal methods can achieve the in situ separation of heterogeneous phases from the multicomponent systems 27 and have been used to achieve the efficient recovery of heterogeneous phases from various slags. 28,29 Therefore, the in situ separation of Crspinel crystals from Cr-bearing slag by supergravity was proposed to efficiently recover Cr from the slag.…”
