Reprocessing of tailings of Chador-Malu iron ore, Iran

摘要

During the last twelve years of exploitation and production at Chador-Malu iron mine, about 27 Mt of tailing is accumulated containing about 31% Fe. This material could be reground as a feasible reserve. The studies of this tailing showed that by regrinding and reprocessing, using high gradient magnetic separation and flotation, a concentrate of 63.31% Fe and 0.058% P, similar to actual flotation concentrate, could be produced.
