Ore pelletizing compositions, devices, systems, and methods using automotive paint sludge as a binder

Abstract

Disclosed herein are methods and compositions useful in recycling automotive paint sludge in the formation of ore pellets. In many embodiments, the pellets are iron ore pellets comprising magnetite ore, and one or more of limestone and bentonite. The automotive paint sludge may be water based or other solvent based. In many embodiments, the disclosed methods and compositions may result in pelletized ore with performance characteristics (hardness, resistance to breakage, porosity, reduction, etc.) that are similar or superior to pelletized ore lacking paint sludge.
