The Jones wet high intensity magnetic separator was developed in 1956.The structure of the Jones separator is shown in Figure 9.6 and consists mainly of an iron core electromagnet, a vertical shaft with two separating rings, a driving system, and feeding and product collection devices.
9.5.2 Utilization of subeconomic iron ores. As magnetic separators progress toward larger capacity, higher efficiency, and lower operating costs, some subeconomic iron ores have been utilized in recent years. For example, magnetite iron ore containing only about 4% Fe to 15% Fe and oxidized iron ore of only about 10% Fe to 20% Fe are reported to be utilized.
Suspension Permanent Magnet SMP SMP series permanent suspension magnets are powered by ceramic strontium ferrite magnets, and used for separation of Tramp Iron within non magnetic materials to protect many kinds of Hydro cone, Crusher and Press Mill and other machineries and production lines to avoid damage and depreciation of turnout any Tramp Iron parts.
When the separation interval is 4 mm, the magnetic field selector switch is placed in a strong magnetic field. When the excitation current is 2 AMPERES, the large magnetic field strength is no less than 14000 OE . Transmission structure: consists of electromagnetic vibration feeder, ore storage funnel and ore feeding cone and baffle.

Magnetic separator separates the iron ore feed material into two or more components. If the purpose is to produce a magnetic concentrated iron ore then the other component which is non magnetic is the tailings. In some cases there can also be a possibility of separating the less magnetic third component which is called middlings.
