The invention relates to a 
cleaner production process for synchronously extracting 
vanadium and aluminum from aluminothermic 
vanadium iron 
slag, and belongs to the technical field of 
metallurgy. The technical scheme is that: the 
vanadium iron 
slag is subjected to 
sodium oxide roasting by using high-proportion Na2CO3 as a 
roasting transforming agent, vanadium and aluminum of a clinker obtained after 
sodium oxide roasting are synchronously dissolved out by using an 
aqueous solution, 
sodium vanadate crystals containing aluminum 
hydroxide are crystallized, the purity of the obtained Al(OH)3 is over 95 percent, the purity of vanadium 
pentoxide is over 98 percent, the co-extraction of the vanadium and the aluminum, the separation of the vanadium and the aluminum and the cyclic utilization of 
sodium salt are realized, the 
recovery rate of the vanadium is over 85 percent, the 
recovery rate of the aluminum is over 60 percent, the weight of 
tailings is reduced by 40 to 50 percent after leaching, and the 
tailings can be used for preparing an aluminum-
magnesium flocculant by an acid method. The high-efficiency extraction of the vanadium is realized, the resource reutilization of an 
aluminum element in the 
slag is also realized, 
wastewater discharge is avoided in the whole production process, CO2 gas for 
carbonation can be replaced by roasting 
flue gas, the proportion of carbon emission isreduced, and the process has remarkable economic and environmental benefits, and can be effectively applied to the treatment of the aluminothermic vanadium iron slag and related materials.
