A field experiment was conducted to study migration of the elements from the copper smelting slag recycling waste into high-moor peat and lawn grasses. The waste was obtained by crushing the cast slag (particle size 0.05 mm) followed by flotation extraction of copper concentrate. The waste was introduced into lime-neutralized peat in the ratio of 5%, …

Fayalite is the main phase of copper slag and a type of Fe silicate glass that is composed of a polymerized network of silicate tetrahedrons, in which SiO 2 and FeO are generally considered as network formers and modifiers, respectively. The structure of fayalite is shown in Fig. 13 [107].In iron silicate glass, O 2− exists in the form of bridging and non-bridging oxygens (BOs and …
