chrome ore sand and its uses

ICDA - Uses of chrome - Foundry sandRefractory chromite in granular form (chromite sand) is widely used in the foundry industry for both ferrous and non-ferrous castings, particularly in the automotive, shipbuilding and heavy-engineering sectors. The merits of chromite foundry sands include high refractoriness, good chemical stability, low thermal expansion.chrome ore sand and its uses,LKAB - Chromite Sand - Spinel - for the foundry industryChromite Sand. Chromite Sand is a naturally occurring spinel consisting primarily of the oxides of chrome and iron. It is a by-product of ferro-chrome production and is mainly used in foundry applications and in glass production.

chromite sand and flour - Steel Founders' Society of America1.1 Chromite sand. 1.1.1 Primarily for use as either a molding sand or as a core sand in the production of steel castings. 1.1.2 Foundry grade chromite sand is derived from naturally occurring chrome ore deposits. The grains are irregularly shaped, angular and commonly with somewhat curved faces. The color is jet black.chrome ore sand and its uses,Chromite - WikipediaChromite is an iron chromium oxide: FeCr2O4. It is an oxide mineral belonging to the spinel group. Magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr2O4); substitution of aluminium occurs leading to hercynite (FeAl2O4). It is by far the most industrially important.
