iron ore beneficiation flotation

The company carried out a test campaign with its own Hybrid Flotation cell in the laboratory. An iron ore concentrate containing 67 % Fe and 1.3 % S was used as the feed material. The target of the test campaign was to reduce the sulfur content to below 0.4 % in the final concentrate. The required iron recovery was at least 95 %.
