Dry Magnetic Separation of Iron Ore of the Bakchar Deposit
As noted above, a Bakchar iron ore relates to the high-grade ores containing in natural form up to 43.9% of iron. But chemical analysis indicated that before the magnetic separation that ore had already contained 46.2% of iron. Probably, this is explained by centralization of the ferruginous particles in a selected fraction (–0.63 +0.5 mm). A
