ORC presently has three primary minerals that are marketable products; chromite, garnet and zircon.
Chromite
The

In all steel casting, a variety of minerals and sands are used to coat the molds, which affect the cooling process and finish of the steel. Chromite has superior thermal qualities slowing the cooling process which reduces cracks in the mold, giving the finished product more strength and a smoother finish.
Water jet machines use very small volumes of water mixed with an abrasive (garnet, in most applications) and use specialized pumps that can generate pressure up to 50,000 pounds per square inch. It produces a laser like stream of high pressure material that can cut through steel, aluminum, etc.
The use of garnet in precision water jet cutting is increasing and the domestic
Zircon
Zircon is used in refractory bricks and as foundry sand due to its superior heat resistant characteristics (high melting point). It is typically used in specialized applications such as glass making; aluminum engine block casting and investment casting, e.g. golf club heads. Zircon is also suited for ceramic tile glazing. Its use as a molding sand for high-grade castings in the auto and aircraft industries continues to expand and the
High Iron / Ilmenite
Based on testing by a leading manufacturer of foundry products, the ORC High Iron Ilmenite product has been determined to have excellent properties in use as an additive for certain foundry applications due to its unique chemical and sizing grain structure. This ORC mineral can be a substitute for other minerals that are used in foundry applications.
