Preliminary experiments to assess the effectiveness of magnetite powder
To our knowledge, magnetite powder is close to an ideal tracer among existing erosion tracer. The magnetite powder is pure black powder, commonly used as auxiliary material in the process of coal mining or as pigment. The powder belongs to low-cost minerals commonly processed as silt-sized particles.

Fluidized magnetization roasting of refractory siderite
We systematically studied and proposed the fluidized preoxidation-low-temperature reduction magnetization roasting process for siderite. We found that the maghemite generated during the air oxidation roasting of siderite would be further reduced into wüstite at 500 and 550°C due to the unstable intermediate product magnetite …

Mechanisms in oxidation and sintering of magnetite iron …
Thermal volume changes and oxidation mechanisms in magnetite iron ore green pellets balled with 0.5% bentonite binder, as a function of raw material fineness and pellet porosity, are shown. When a pellet starts to oxidize, a shell of hematite is formed around the pellet while the core still is magnetite. Dilatation curves were measured under …

Iron ore magnetite processing
Iron ore magnetite processing (LIMS, MIMS, WHIMS, Davis Tubes) The increased worldwide demand for steel in recent decades has led to an increase in the exploitation of magnetite iron ore deposits as an alternative to hematite DSO ores. Magnetite concentrate is a higher-grade product than hematite and very desirable as a smelter feed.
