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.

Upgrading of Manganese from Waste Silicomanganese .

manganese from waste silicomanganese slag in this study. In order to feed the silicomanganese slag into the dry magnetic separator, the slag was first ground into under 500mm, and then the powder was sieved into several sizes. Figure 3 shows the relationship between the contents of manganese and iron and the percentage yield of each particle ...

In addition, depending on the smelting temperature and the acidity or basicity of the slag, silica can be reduced to silicon and enter the molten metal. High-carbon ferromanganese The primary product of the smelting process outlined above is a carbon-saturated ferroalloy containing 76 to 80 percent manganese, 12 to 15 percent iron, up to 7.5 percent carbon, and up to 1.2 percent silicon.
