FIELD: complex usage of raw materials in ferrous metallurgy, namely processing blast furnace production slimes containing iron, zinc, sulfur and other metals, possibly extraction of harmful zinc impurities preventing participation of iron-containing raw materials in metallurgical conversion from slimes of scrubbing at blast furnace production.
SUBSTANCE: zinc extraction is realized by magnetic separation method. In order to convert zinc ferrites and zincates to non-magnetic fraction, magnetic separation is performed in magnetic field with intensity up to 96 kA/m.
EFFECT: improved efficiency of zinc extraction from blast furnace production slimes due to lowered mass content of zinc in magnetic product.
