METALLURGICAL DUST RECYCLE METHOD Russian patent published in 2019 - IPC C22B7/02 B09B3/00 C08K3/10 

FIELD: metallurgy.

SUBSTANCE: invention relates to use (recycling) of metallurgical dust formed during production of ferrous metals from raw material of ore deposits and trapped by electrostatic precipitators of air purification systems with particles of nanometer size containing, besides iron oxides, copper, chrome, considerable amount of zinc oxides (up to 20 %). Collected metallurgical dust is packed in metal containers. Then, it is cooled and dust is sieved through sieve of 63 mcm. Further, the obtained dust is used as an activator of vulcanisation accelerators by adding together rubber with a rubber mixture in amount of 2 to 6 weight parts by 100 weight parts rubber.

EFFECT: method widens spheres of application of metallurgical dust.
