iron ore or slag

Iron and Steel Slag Statistics and Information

The iron ore is a mixture of iron oxides, silica, and alumina. From this and the added fluxing agents molten slag and iron are formed. The physical characteristics such as density, porosity, and particle size, are affected by the cooling rates and chemical composition.

What is Slag Glass? Price Guide and History

Aug 18, 2020  When iron ore is smelted in that process, the remaining residue is a glass-like, often glossy material that takes on different colors depending on the minerals and elements present in the iron. The visual marbling of this slag is reminiscent of slag glass, however, the presence of actual slag in slag glass pieces depends on how it was created.

Types of iron and steel slag : NIPPON SLAG ASSOCIATION

Blast furnace slag is recovered by melting separation from blast furnaces that produce molten pig iron. It consists of non-ferrous components contained in the iron ore together with limestone as an auxiliary materials and ash from coke. Approximately 290 kg of slag is generated for each ton of pig iron.

Slag - Wikipedia

Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium. Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide.
