Processing of high alumina iron ore slimes using classification and flotation

► Recovering iron values from high alumina iron ore slimes from Joda, India ► Classification using two stage hydrocyclone to remove ultra fine particles and to upgrade iron values ► Studies on the effect of hydrocyclone design variables on grade and recovery ► Flotation of hydrocyclone underflow with amines and fatty acid ► Investigation on the effect of percent solids and depressant dosage on flotation performance
