Recovery of manganese from silicomanganese slag by means ...

01/12/2015  A hydrometallurgical process is proposed in this paper to recover manganese from silicomanganese slag. The paper reports the digestion–leaching experiments and precipitation and electrowinning assays to recover Mn from this residue. Silicomanganese slag was first treated with sulfuric acid in a furnace at 200 °C.

RECYCLING THE RECOVERY OF MANGANESE AND GENERATION

1. INTRODUCTION Ferromanganese (and silicomanganese) production lead to the formation of slags, which contain considerable amounts of unreduced manganese, and are typically discarded on slag heaps. Approximately 20 million tons have accumulated on slag dumps in South Africa and a further 0.5 million tons are added every year.

Recycling steelmaking slag in ironmaking processes is an efficient method to decrease the amount of generated steelmaking slag1. However, since phosphorus and manganese can easily accumulate in hot metal under ironmaking conditions, the selective recovery of phosphorus and manganese is necessary. Steelmaking slag contains around 4 wt% of phosphorus and 6 wt% of manganese. Both phosphorus
