Efficiency of the comminution operations is traditionally assessed based on operating cost and energy consumption. Traditionally, the lowest operating cost was achieved by multi-stage fully autogenous grinding due to elimination of steel grinding media costs which may represent up to 50% of the grinding cost.
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.
In this research, we successfully designed and synthesized a new core-shell-structured inorganic-organic hybrid magnetic nanocatalyst via the ethylene diamine immobilized to the core-shell Fe 3 O 4 nanomagnetic particles (Fe 3 O 4 @SiO 2 @(CH 2) 3 /EDA). A variety of analyses such as fourier-transform infrared spectroscopy (FT-IR), energy-dispersive …

Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of …
