An overview of the beneficiation of iron ores via reverse cationic
Iron is one of the most common elements in Earth's crust. The primary industrial types of iron-bearing minerals include oxides and hydroxides and, to a lesser extent, carbonates: magnetite [Fe 3 O 4], hematite [Fe 2 O 3], goethite [FeO(OH)], limonite [FeO(OH) × nH 2 O] and siderite [FeCO 3].The genesis of iron ore deposits is variable, similar to numerous other ore …

Beneficiation of Iron Ores
Fig 3 Types of processing ores. The wet processing (Fig 4) is normally practiced for low / medium grade (60 % Fe to 63 % Fe) hematite iron ore. The wet process consists of multi-stage crushing followed by different stages of washing in the form of scrubbing and / or screening, and classification etc., but the advantage is only partial removal of adhered alumina and free …

Phosphate Beneficiation
Flotation separates valuable minerals (copper, lead, zinc, iron, and phosphate too) from the contaminating minerals in the ore (sand in this case). In the direct flotation process the valuable mineral is coated with a special hydrocarbon (fatty acid) that makes coated particles behave the same as a waxed car.
