摘要： A process for obtaining vanadium component in the form of vanadium oxide from gasifier slag is disclosed. The process comprises pulverizing the slag to obtain pulverized slag, which is blended with water and an alkali salt to obtain a slurry. The slurry is dried and then roasted in the presence of air to obtain a roasted slag. The roasted slag is leached to obtain a first filtrate comprising the vanadium component. The first filtrate is reacted with a magnesium salt to remove a silica component in the form of a precipitate. The silica free second filtrate is reacted with an ammonium salt to obtain ammonium metavanadate, which is further calcined to obtain the significant amount of vanadium pentoxide (V2O5).

The first plant part is provided with crushing and separation means configured to extract ferrous materials, non-ferrous metals and plastic materials from the residues from crushing. The separation means are provided with a granulator system configured to reduce, in dry mode and without pre-screening stages, the residues from crushing into a stream of granular material. The second plant part is provided with means to treat and size the plastic materials configured to transform the plastic materials into additive material to be used, in particular, in iron and steel plants such as blast furnaces, electric arc furnaces or suchlike. The means to treat and size the plastic materials includes a dry system for cutting and/or grinding the plastic materials.
