The analysis for magnetite or 'magnetite equivalent' by means of magnetic susceptibility is more rapid, lower in cost, and, in general, as precise as other methods of analysis.'Magnetite equivalent' analysis is affected by grain size if the individual particles are less than 40 microns in diameter, by the remnant magnetization if greater than about 12 percent of saturation magnetization, and ...
Wet Grinding of VanadiumTitanium Magnetite Concentrate in ...
This paper studies the grinding behaviour of vanadiumtitanium magnetite concentrate in a ball mill. The grinding kinetics, surface morphology, lattice distortion, wettability and moisture capacity were analysed. Grinding kinetics equation was established based on population balances model with the size distribution data from a laser diffraction technique.
Mill (grinding)
To calculate the needed grinding work against the grain size changing three semiempirical models are used. These can be related to the Hukki relationship between particle size and the energy required to break the particles. In stirred mills, the Hukki relationship does not apply and instead, experimentation has to be performed to determine any relationship. Kick for d > 50 mm ...

The grain size of the magnetite and its degree of commingling with the silica groundmass determine the grind size to which the rock must be comminuted to enable efficient magnetic separation to provide a high purity magnetite concentrate. This determines the energy inputs required to run a milling operation. Mining of banded iron formations involves coarse crushing and screening, followed by ...

A process for upgrading lowgrade magnetitecontaining iron ore with minimum fine grinding. The dry ore is first comminuted to between about threefourths inch and 10 mesh particle size and magnetically separated. The dry tailing is discarded and the concentrate is ground to between about 20 and 100 mesh and again subjected to dry magnetic separation.
Grinding
Grinding equipment for mineral processing. The final fineness of the product mainly depends on the number of times the ore particles pass through the grinder. The longer the grinding, the smaller the particle size. Separate crushing and grinding steps are necessary, the ball mill can only receive the broken ore particle, and then grind to the ...
