These three ore bodies are principally beneficiated by froth flotation. During the beneficiation of chromite hosted PGE's by froth flotation, chromite represents the principal gangue mineral. This is particularly true for the UG2 main seam.

Chrome ore is the basic material for magnesia chrome or chrome magnesite bricks and compounds in the refractory sector, but it also serves as premium moulding sand in foundries and the metallurgical industry. The repeated use of black sand in the …

All the ore mined in Maryland and the adjacent region in southeastern Pennsylvania was shipped to Baltimore, and nearly all of the chrome produced in the world between 1828 and 1850 came here. Isaac Tyson, Jr. established a chrome plant in Baltimore in 1845, and thereby gained a monopoly in the chemical use of chrome as well as in its mining.

Because chrome is a very hard metal and has a low coefficient of friction, chrome plating was also used for extending the life of parts that receive heavy wear, such as automobile cylinders, and was useful in boiler pipes to prevent build-up of scale (mineral deposits). Refractory materials are highly resistant to heat and are chemically stable.
