In this paper, a sample from Tange-zagh iron mine was characterized by gravity and magnetic separation methods. The mineralogical studies showed that hematite and goethite are the main iron-bearing minerals with insignificant amounts of FeO. The results indicated that spiral separation yields higher separation efficiency than others.
Iron ore beneficiation can be brought about through three approaches, namely, selective dissolution, microbially induced flotation, and selective flocculation–dispersion. The bioprocesses are specially suited to treat fines, slimes, and waste tailings. 4. Potential applications include i. Dephosphorization ii. Desulfurization iii. Desiliconization

commonly used beneficiation methods for iron ores are the gravity and magnetic separation techniques [4−6]. Gravity separation is widely used in mineral bene-fication practices for its low-cost, ease of operation and easy to control, and eco-friendly nature [4, 7−9]. It is an appropriate method of concentration for size

Appropriate beneficiation process has to be advanced to reduce the waste generation in mines and for the sustainable growth of the iron ore industry some. Major reason for difficulty in beneficiation of BHJ is revealed from characterization studies which show the intergrowth of haematite and quartz.
1） Single Weak Magnetic Iron Ore Beneficiation Process It includes metamorphic, sedimentary, hydrothermal and weathered typed hematite, siderite, limonite and hematite (specularite)-siderite. This kind of ore has many kinds, and wide range of disseminated size. There are two main processes used in the beneficiation of iron ore.
Six steps to process iron ore 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.
