LiDoVa

The main objective of LiDoVa is the extraction of 2 high-grade products from LD slags, which are produced in the converter during the further processing of pig iron into steel. These are vanadium (compounds) and construction material for the building materials industry. In the project consortium, research will be carried out on three main pillars: (1) Development and upscaling of a process for the extraction of vanadium and the production of V2O5 and ferrovanadium from LD slag (2) Characterization and valorization of the slag as well as the residues produced in the process for the production of cement-free building materials based on alkali-activated materials, (3) Economic and especially ecological considerations.

In line with the implementation of this zero-waste concept, this opens up the possibility of using the processed LD slag as an alternative to the most important reactive composite materials to date, granulated blast furnace slag and coal fly ash, while at the same time recovering the vanadium, which is only available in limited quantities worldwide in the necessary quality, for use, for example, in modern energy storage systems.
