Study of the Processes of Metal Recovery from Steel Slags

Nickel recovery from electric arc furnace slag by magnetic separation

“…Slags from pyrometallurgical treatment of ores sometimes contain valuable metal in increased concentration because of the inefficient separation of metal phase from slag. Hence, they are actually considered as a secondary resource of metals rather than an end-waste and have been applied as a resource material in many areas [9][10][11][12][13][14][15][16]. According to the origin and characteristics, the principal slags can be classified into ferrous and nonferrous.…”

Separation of the magnetic fraction from the slags originated during steel production

“…Thus, complete separation of the slag from the metal is not possible [9]. The magnetic part does not necessarily mean metallic only but it contains unseparated slag and magnetic oxide as well [10]. The recycling of the slag components has made important progress in the recent years [11].…”
