A hydrometallurgical process for recovering vanadium from slag, a byproduct of steelmaking, has been significantly scaled up. Previously deployed at minipilot and bench scales, the process, developed by Neometals Ltd., has now been expanded by a factor of 25, to process 14 tons of slag (corresponding to a throughput of around 25 kg/h) from three different steel mills operated by SSAB. In this ...

The technological factors required to improve the operational properties of granulated metallurgical slags demanded in the building industry have been analyzed. In order to satisfy these factors, a new technology for hydrovacuum granulation of slag melts (HVG) has been developed. It is shown that the main advantage of the proposed HVG process is the provision of forced highspeed vortex ...

Initially, at a steel mill, iron ore, flux, and fuel (coke) are added into an oxygen blast furnace. The materials combine and react to form liquid hot metal, gasses, and blast furnace (ironmaking) slag. Blast furnace slags typically contain % iron (NSA, 2000) and are commonly used for applications such as industrial aggregates, cement ...

Ferrous slag forms as a dominantly calcium silicate melt that floats on top of the molten crude iron or steel; the slag is then removed from the liquid metal. For typical iron ore grades (60 to 66 percent iron), blast furnace slag output will be about to metric tons of slag per ton of crude iron produced.

Abstract. An integrated steel plant generates 200250 kg of steel making slag for every tonne of steel produced. These slags contain nonuniformly distributed iron in metallic form, inevitably carried into the slag pot during deslagging. The steel slag is subjected to crushing/magnetic separation to generate different sizes of slag products ...
