In-Process Separation of Zinc From BOF Offgas Cleaning System Solid Wastes

摘要

BOF offgas cleaning system solid wastes often contain zinc, whose concentration is generally too high to recycle the wastes for iron through blast furnaces, but too low to economically treat them for zinc through zinc recovery facilities. In-process separation of zinc from BOF offgas solid wastes is a strategy to separate zinc from BOF offgas solid wastes by utilizing multi-level dust collectors in sequence in BOF offgas cleaning systems.
