Hematite: Grounding, Focus, & Centering - Crystal Benefits

Written by Nigel Ford. Hematite is widely regarded as being a very grounding stone. While all crystals can be considered at least somewhat grounding (they do come from the ground, after all), hematite is particularly well-known for being a very grounding stone.. Hematite has a fabulous, silvery sheen that can be seen when light reflects off the stone.

In place of initially grinding 85 to 90% minus 325, the grind if coarsened to 80-85% minus 325-mesh will result in greater initial tonnage treated per mill section. Considerable advantage is to be gained by this approach. Free-Flow "Sub-A" Flotation is a solution to the effective removal of silica from magnetic taconite concentrates.

In addition, the orebodies are mantled by canga, (detrital and lateritic material). The hematite ores are interpreted to be due to hypogene enrichment of the itabirites, while the friable ores are the result of supergene leaching of silica and iron enrichment. The geological resource is stated at 1.3 Gt of hematite ore and 2.8 Gt of friable ores.
