Goethite Mineral Physical - Optical Properties, Uses ...

Goethite can also occur in stalactitic or massive forms and in tufts and drusy coatings. Goethite is an iron oxide hydroxide, although manganese can substitute for up to 5 percent of the iron. It forms as a weathering product in the oxidation zones of veins of iron minerals, such as pyrite, magnetite and siderite. Goethite may occur with these minerals in the gossan, or iron hat, which is the weathered capping of an iron ore

Understanding the effects of goethitic iron ore – Process ...

18/04/2017  Iron ore composition. Compared with hematite and magnetite, goethite has a much more diverse range of textural forms and occurrences, and its influence on iron ore processing is less understood. Currently, most analysis of the effects of goethite on mine performance considers only the chemistry of the ore and not its textural components. Through improved textural classification of goethitic ores we can reframe the perceptions the industry has of goethite

mindat - Goethite

Goethite is found as an supergene oxidizing (weathering) product of many iron minerals. In the near surface, it was an important iron ore mineral developed over banded iron formations. It is found in sedimentary rocks as concretions and was mined from bog ore deposits. It is a component of limonite and is found in the weathered gossans of sulfide rich ore deposits and was used as a prospecting ...

Goethite - Buy Goethite Mineral Specimens - UK Shop

Goethite is typically used simply as an Iron ore. It is smelted to produce Iron, which is then usually converted to Steel. It is likely that Goethite has been smelted for a long time, as it is commonly found as ‘bog Iron’. Bog Iron was used by the Norse Vikings to make their excellent quality swords, which were made of some of the purest quality Iron in the world at the time.
