FIELD: metallurgy.
SUBSTANCE: invention refers to metallurgy, particularly to method of chromium slag neutralisation. Method includes preparation of pellets of chromium slag, coal dust or coke fines and binding substance. In the production train of agglomeration or train of pellets production the pellet shells out of feed materials of agglomerates, or pellets, or collected dust from iron wastes of the metallurgy are made, and complex pellets are made as per method of secondary pelletization, then agglomerates or pellets are formed. High temperature during agglomeration or annealing ensures creation of the restoration atmosphere inside the pellet shells performing the chromium slag pre-treatment.
EFFECT: invention use ensures effective, economic and ecologic neutralisation of the chromium slag with disposal of the collected dust from the iron-containing metallurgical wastes.
