Abstract

The present report documents the results of industrial-scale utilization of ultra-fine iron ore stored in tailing ponds during previous years of productions. The tailings were studied and technically evaluated in pilot plant scale by high intensity magnetic separation with the aim to segregate quartz from hematite. The declared aim of the project was the recovery of a concentrate product with the SiO2 content limited to a maximum of 3.0 % and a grain size range dictated by the process. The philosophy of the company was to effectuate the idea of utilizing technically and economically the available raw material by an environmentally sound method.
