  • Process for cold briquetting and pelletization of ferrous or non-ferrous ores or mineral fines by iron bearing hydraulic mineral binder
    Patent number: 6921427
    Abstract: The present invention provides a process for cold briquetting and pelletization of ferrous or non-ferrous or mineral fines using iron bearing hydraulic mineral binders for metallurgical applications, said process consisting the steps of: mixing 80-95% by Wt. of a metallurgical/mineral/carbonaceous/oil contaminated dust/fines/sludge with 3-10% by Wt. of an iron bearing hydraulic mineral binder and optionally with 2-6% by Wt. water and 0.05 to 0.20% by Wt. of a surface active agent to form a homogenized dry mix/slurry, pelletizing/compacting the dry mix/slurry to form an agglomerated mass, and curing the agglomerated mass for 3-20 days by exposing the agglomerated mass to atmospheric air for 10-14 hours followed by moisture treatment.
