Abstract
Method for treating an incinerated waste material feedstock to obtain a "free-from-ash" ferrous metal product and/or a "metal-free" ash product are disclosed which provide for early separation of the initial feedstock into a predominately ash stream and predominately ferrous metal stream by stepped separation based on size of the material at different stages of the process.
