File:Hematite (iron ore) (weathered zone in the Biwabik ...Summary. Early mining operations exploited highgrade iron ore in the form of earthy hematite and limonite in the weathered zone in the surface and nearsurface portions of the Biwabik IronFormation. The weathered zone formed as groundwater leached out silica from taconite rocks, resulting in a deposit rich in iron oxide and low in quartz.

ReProcessing Gold Tailings in South Africaform of hematite (50 75%), followed by basic iron sulphate (20 to 30%), with only about 10% in solution as ferric sulphate. The data suggested that ~90% of the basic iron sulphate decomposed to ferric sulphate in solution during hot curing, and there was no change in the amount of hematite (after correction for mass loss in hot curing).
