Chromite Ore - an overview ScienceDirect Topics

Chromite was initially used as a refractory in France, and bricks of solid chromite cut straight from the mine were used without further refinement or processing up until the 1890s. As a cost-saving measure, manufacturers developed refractory bricks made of crushed chromite and resins that were shaped into bricks. The use of chromium as a refractory material declined in the late 1900s as other ...

Uses of Chromium Supply, Demand, Production, Resources

Chromite, the only ore of chromium, was first discovered in the United States sometime about 1808 on the farm of Isaac Tyson, Jr., just north of Baltimore, Md. Scattered deposits of chromium minerals in an area of northeastern Maryland and southeastern Pennsylvania were the source of nearly all of the chromium products in the world between 1828 and 1850. Currently, the only domestic commercial ...

What is Chromite Used For? Occurrence and Uses of

An important use of chromite is in the manufacture of refractories, largely in the form of chromite brick. Raw chromite ore is used directly for this purpose. The ore is ground, mixed with a binder, and pressed into bricks under a pressure of 10,000 to 15,000 psi (about 700-1,000 kg per sq cm). Chromite refractories, being chemically neutral, are used in lining parts of furnaces for ...
