MAGNETIC SEPARATIONPRINCIPLES AND APPLICATION
Magnetic Separation is one of the physical concentration processes that utilizes the differences in magnetic properties of various minerals present in the ore body The magnetic fraction may be valuable or gangue depending upon its end use in a particular process and so also the nonmagnetic fraction, eg, separation of magnetite (magnetic) from quartz (nonmagnetic), separation of tin Magnetic separator and permanent magnet The magnetic separator uses the magnetic difference between minerals for sorting, plays the role of improving the grade of ore, purifying solidliquid materials, and recycling waste It is the most widely used and highly versatile machine in the industry One Magnetic separators are widely used in Magnetic separator and permanent magnet OsencAbstract: In this research, the efficiency of magnetic separation methods for processing of a lowgrade iron pigments ore (red ochre) has been studied Based on the mineralogical analyses (XRD), thin section and polish studies, the reserve is an ironInvestigation of Efficiency of Magnetic Separation
Hematite Ore, Hematite Mineral, Hematite Beneficiation
The magnetic separation can separate regular coarse concentrates and tailings in time, which fits the principle of early recovery and early discarding as possible It also reduces the flotation workload and costs Strong magnetic separation can recover the fine particle iron ore It has double effects of desliming and discarding tailings Effective separation of iron values from iron ore slimes using a wet magnetic separator and selective magnetic coating is reported The selectivity of coating for enhancing the magnetic response of iron particles was achieved by controlling the surface properties of the particles, ie, electrokinetics potential, through pH adjustment and use of sodium hexametaphosphates as the dispersantRecovery of Iron Values from Iron Ore Slimes by Selective
