METHOD OF PREPARATION OF WET IRON SLUDGE metallurgical production By sintering

摘要

1. A process for the preparation of wet ferrous metallurgical sludges to agglomeration comprising mixing them with dry metallurgical production waste, characterized in that the preparation comprises screening removal of sludge fractions larger than 1.00 mm, a subsequent dewatering and thickening of sludge draining the liquid phase, recovery of the resulting suspension by magnetic separation of iron-containing fractions and subsequent removal therefrom classification hydrodynamic ballast substances and obtained by dehydration hydrochloric slurry with a high content of iron-containing fractions and iron pre-extracted fractions and mixing them with dry metallurgical production waste. ! 2. Method according to claim 1, characterized in that the dry waste metallurgical flue dust are used, and / or a suction dust Limekiln plants and / or plant dust electrostatic domain. ! 3. A method according to claim 1, characterized in that the sludge dehydration condensation is carried out until 25-30% of the solid.
