REVALUATION OF INDUSTRIAL-WASTE MATERIALS - PERSPECTIVES FOR STEELWORKS FLUFF

Within the framework of industrial waste revaluation a preliminary stu dy was carried out in order to consider the real possibilities of usin g Puff from steelworks as a power source or for heavy metal recovery. Fluff is a waste material prevalently arising from crushing of the scr apped motor cars employed as raw material in steel production; it is a very heterogeneous material whose dumping is at the moment its expens ive disposal, but which on well defined conditions could have a lawful use as a power source. Besides, the presence of heavy metals, some of them commercially interesting, makes their recovery useful. In this c ontext some simple types of treatment (i.e. screening, flotation, magn etic separation) were carried out on a sample of fluff and some of the m resulted important as preliminar operations for a more profitable ut ilizzation of this waste material.
