furnaces via modified ironmaking processes. Typically, vanadium is recovered as a by-product from the ironmaking process, while the diluted titania slag is stockpiled. Fluxless smelting in a direct-current open-arc furnace is proposed as an opportunity to improve iron and vanadium recovery and potentially unlock the titanium as a slag product.

Electroslag Remelting Furnaces

In its molten state the slag is electrically conductive and acts like a resistance heating element when a high current is passed between the electrode and the mold. With the continued passage of the electric current, the slag becomes superheated. The electrode tip is immersed in this superheated slag and begins to melt.

Preparation of Synthetic Titania Slag Relevant to the …

A high titania slag that is used as a feedstock for TiO2 manufacturing is obtained by ilmenite smelting (FeO.TiO2). The composition of the slag obtained by smelting is dependent on the composition of the mineral used for slag preparation, i.e., ilmenite in our study. At the laboratory scale, ilmenite slags are mostly obtained by using ilmenite as the raw material. An …

Scalable Synthesis of a Porous Micro Si/Si-Ti Alloy Anode for …
