Goethite are excellent stones to use to help you if you have lost a loved one. They have a strong vibration that aids you to heal grief and will help you to open yourself up to love and compassion. They aid emotional healing and at the same time helps you to release past life feelings and energy that no longer benefit you.

Limonite (/ ˈ l aɪ. m ə ˌ n aɪ t /) is an iron ore consisting of a mixture of hydrated iron(III) oxide-hydroxides in varying composition. The generic formula is frequently written as FeO(OH)· n H 2 O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely. Limonite is one of the three principal iron ores, the others being hematite and magnetite ...

limonite, one of the major iron minerals, hydrated ferric oxide (FeO(OH)· n H 2 O). It was originally considered one of a series of such oxides; later it was thought to be the amorphous equivalent of goethite and lepidocrocite, but X-ray studies have shown that most so-called limonite is actually goethite.. The name limonite properly should be restricted to impure hydrated iron oxide (with ...

Limonite type laterites (or oxide type) are highly enriched in iron due to very strong leaching of magnesium and silica. They consist largely of goethite and contain 1-2% nickel incorporated in goethite. Absence of the limonite zone in the ore deposits is due to erosion. Silicate type (or saprolite type) nickel ore formed beneath the limonite ...

The difference between magnesium and silicon oxide in lateritic nickel ore plays an important role in the selective reduction process. Therefore, in this work, the selective reduction of saprolite and limonite was carried out to reveal the effect of lateritic nickel ore basicity (MgO/SiO 2 ratio) on phase transformation and microstructure of ...

Thanks for the correction, I had a wrong idea in my head! And you're right about the crystal form being the most helpful, but in the beginning of this thread, there was made the remark that the only difference between hematite and goethite is the crystal system, so I tried to correct that.
