Generally, during the flotation process, silicon-adsorbed terpenic oil attached to the bubbles and floated upward into the froth layer, thus continuously leaving silicate tailings in the cell. Thus, the silicon concentrate can be recovered more efficiently from the MG-Si refined slag by using terpenic oil as the surfactant.

Metallurgical-grade silicon-refined waste slag (MGSRS) was produced during the MG-Si refining production process, which occupies huge amounts of land resources, caused the loss of nearly 110,000 tons of MG-Si every year. Therefore, it is of great significance to recover the elemental silicon from MGSRS. However, because silicon is tightly …

no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.

Froth flotation has been widely used in upgrading iron ores. Iron ore flotation can be performed in two technical routes: direct flotation of iron oxides and reverse flotation of gangue minerals with depression of iron oxides. Nowadays, reverse flotation is the most commonly used route in iron ore flotation. This review is focused …
