Magnetized drums collect magnetic material, so it can be further concentrated (magnetite iron minerals content). The lighter particles that were separated during the spiral gravity separation step are rolled into balls (combined with bentonite or a similar binding agent) and cooked in an induction oven. This process is known as pelletization.

The Karara Mine concentrator commenced operation in November 2012 to produce high-grade magnetite concentrate. The circuit consists of three stages of comminution plus magnetic separation at each stage for early gangue rejection. High-Pressure Grinding Rolls (HPGRs) are used for fine crushing, followed by ball mills and TowerMills in secondary and fine grinding …

In some cases, the final magnet shape is conducive to processing with a shaped diamond grinding wheel such as arcs and bread loafs. Product in approximate final shape is fed past the grinding wheel which provides the precise dimensions. For lower volume manufacturing of these complex shapes, EDM machining is commonly used.

Magnetite ore and processing. A general processing circuit for magnetite ore is initial crushing and screening of run of mine (ROM) ore to <6 mm. The ore is then milled to a specified grind size to liberate the iron minerals from the gangue, then processed further to produce a magnetite concentrate, commonly by a wet magnetic separation process.

mineral processing - mineral processing - Concentration: Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour (optical sorting), density (gravity …

Separation process of iron ore . At present, there are about 300 kinds of iron-bearing minerals found in nature. According to their chemical composition, iron ore can be divided into magnetite, hematite, limonite and siderite; The specific magnetic susceptibility of the material is different, and iron ore is divided into strong magnetic and weak magnetic minerals, which also …

11.23.2 Process Description2-5,41 Processing of taconite consists of crushing and grinding the ore to liberate iron-bearing particles, concentrating the ore by separating the particles from the waste material (gangue), and pelletizing the iron ore concentrate. A simplified flow diagram of these processing steps is shown in Figure 11.23-1.

Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.
