The Formation, Extraction and Uses of Olivine - GulpMatrix

26/01/2021  Uses of Olivine. Olivine is a mineral that is not often used in industry. This mineral is used in metallurgical processes as a slag conditioner. High-magnesium olivine (forsterite) is added to blast furnaces to remove impurities from steel and to form a slag. This mineral has also been used as a refractory material. It is used to make refractory brick and used as a casting sand. Both of these ...

Olivine - Rock-Forming Minerals

Olivine is a common mineral in dark-colored igneous rocks because these rocks are rich in iron and magnesium (rocks rich in iron-bearing minerals tend to be either black or at least dark-colored). These chemical elements (Mg and Fe) are the essential components of olivine which has the following chemical formula: (Mg,Fe) 2 SiO 4. Magnesium and iron can replace each other in all proportions ...

Olivine sand and the FENOTEC binder process for the ...

Olivine sand is an ideal mineral for the production of manganese steel castings. It is however difficult to use successfully in a foundry environment for many well-known reasons. This article by Bob Simpson of Foseco UK describes how Metso Steel Foundry in Czech Republic succeeded in applying this material in combination with the FENOTEC* binder process to achieve very high sand reclamation ...

Two types of olivine mineral were tested to investigate the effect of pre-treatment on the leaching behavior: fresh olivine (GL30, Eurogrit B.V., Papendrecht, The Netherlands) and fully carbonated olivine. The fresh olivine was milled using a centrifugal mill (Retsch ZM100, 1400 rpm, 80 μm sieve mesh), resulting in a material with 86 vol % below 80 μm, and the average mean diameter (D{4,3 ...

3.3 Crystallization of Magma – Physical Geology

Of the common silicate minerals, olivine normally crystallizes first, at between 1200° and 1300°C. As the temperature drops, and assuming that some silica remains in the magma, the olivine crystals react (combine) with some of the silica in the magma (see Box 3.1) to form pyroxene. As long as there is silica remaining and the rate of cooling is slow, this process continues down the ...

Mineral Formulae Recalculation - SERC

For some minerals (pyroxenes, olivine), by making the assumption that all the cation-sites are full and the mineral has perfect charge balance, the proportion of the Fe that is Fe +3 can be calculated to satisfy that assumption. For other minerals (amphiboles, micas), upper and lower limits to the proportion of Fe that is Fe +3 can be calculated based on stoichiometric constrains. Spreadsheets ...
