The collected scrap metal must be sorted to separate ferrous metals from non-ferrous metals and other materials. This is typically done using magnetic separators, which easily attract ferrous metals like iron and steel. Preparation and Cleaning: After sorting, the ferrous metals are cleaned to remove contaminants such as paint, plastic, and rubber.

General properties. Ferrous and non-ferrous smelting processes produce different slags. The smelting of copper, lead and bauxite in non-ferrous smelting, for instance, is designed to remove the iron and silica that often occurs with those ores, and separates them as iron-silicate-based slags. Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron …
