Recycling. Utilization of Non-Ferrous Metallurgical Slags.

Abstract

Effective utilization of slags is one of the most significant issues in the metal industries. Non-ferrous metallurgical slags are becoming widely used in these days, the usage is however far from satisfactory level. In this paper, the current situation and problems on the matter are discussed concerning about copper smelting slag, lead and zinc slag and ferro nickel slag. Simultaneously, relationship between the crystalline phases of these slags changed by cooling condition and the alkali-silica reaction is briefly discussed.
