 · Grinding the magnetite minimally increased the pellet wet drop and dry crush strength values. However, the ground-magnetite strengths did not increase to be equal to the hematite pellet strengths. It was concluded that factors other than particle size were the dominant contributors to higher hematite pellet strengths.

Magnetite

Conversely, fine-grained magnetite ores require fine grinding, often to below 30 μm, to liberate the magnetite from the silica matrix, incurring greater costs and energy consumption. The comminution energy consumption could be over 30 kWh/t, an order of magnitude higher than for hematite ores.

OverGrinding in grinding circuits

In grinding circuits, energy is wasted when particles are ground to a size finer than is necessary. Such overgrinding can be caused when particles are retained in the circuit for too long and continue to be ground even after they have reached the target product size of the circuit.

 · The effect of microwave treatment on the grinding and dissociation characteristics of vanadium titano-magnetite (VTM) ore were investigated using scanning electron microscopy (SEM), nitrogen absorption measurements, particle size distribution measurements, X-ray diffraction (XRD) analysis, Fourier transform infrared (FT-IR) spectroscopic analysis, and magnetic separation. SEM …

On the effect of grinding upon the magnetic properties of …

The dependence of the coercive force of magnetite upon grinding is investigated. The results of annealing experiments lead to the conclusion that the coercive force in this case is caused by stresses in the particles. This conclusion is supported by the results of similar experiments on ferrites having different combinations of crystalline anisotropy and magnetostriction. A semi-quantitative ...
