With increasingly strict environmental legislation, shortage of raw material supply and high metal prices, the implementation of dedicated processes for treating metallurgical residues and recovering their valuable contents becomes more and more relevant. Lhoist engineers, in association with other partners, work on innovative processes to destroy hydrocarbons contained in various sludge and the recovery of certain metals, ready to be re-used in the plant.
For example, oily sludge and scales are part of metallurgical residues. Today it is possible to recover their iron content in an efficient way without impeding the main iron-steel flowsheet.
