Iron and Chromite

Our hematite is a high-density weighting agent that can be used alone in high-pressure situations or in combination with barite to reduce the total solids content in the drilling fluid at any given mud weight. Vibrantz supplies both low and ultra-low abrasive weighting agent options for customers to reduce wear and tear on their equipment.

These high-quality products are valued for their sulfur content and can be used in a variety of industrial applications.

Our hematite, chromite and pyrite-based products are used for coloration and as performance additives in container glass, flat glass and automotive glass. Densfil is used in commercial building glass cladding to impart solar control and aesthetics and  add color and ultraviolet protection to tinted windshields, back-lights, quarter-lights, and sunroofs for the heavy and light vehicle automotive markets. Additionally, Densfil, Pyritemax and Chromox are used in the production of container glass to achieve green and amber color bottles in the furnace. Relatively small additions color the glass but do not affect the basic properties of the glass except for changes in the lower solar light and energy transmission.

We provide chromite sands and powders used by leading foundries to eliminate casting defects and provide durable color solutions. Our high-purity ChromeCast^® chromite sand provides excellent chill properties for castings with heavy metal sections as well as castings with intricate details. ChromeCast is typically used as a sand media when casting dredge cutters, medium and heavy-duty truck parts, mill rolls, oil pumps and valves and pressure parts.

RedCast^® and BlackCast^® are proven anti-veining agents for foundry castings. RedCast, used in core sand and no-bake molds, eliminates or greatly reduces nitrogen gas defects and reduces expansion defects in low sand to metal ratio casting. It is used in cast iron, nodular iron, and steel foundry applications. BlackCast, also used in core sand and no-bake molds, eliminates or greatly reduces veining for cast iron, nodular iron, and steel foundry applications.

MagnaFloat^® is a ferromagnetic mineral product used for magnetic separation in the coal washing process. MagnaFloat’s high density, greater than 4.9, and superior magnetic content enables excellent efficiency in use through exceedingly high recovery rates. Customers enjoy a lower cost per unit of raw coal.

ChromOx^® is used in both the commercial and residential construction markets to color buff-color ceramic bodies to a cool gray or to color medium-iron bodies to a gray-brown. ChromOx can also be supplied as a slurry grade product and you can “just add water” to develop a stable slurry for liquid dosing for addition to red- or buff-burning bodies.

We are the global leading supplier of red iron oxides for a wide range of coloration applications. Our extensive product library includes  high-quality natural, regenerated and synthetic iron oxides.  As through-the-body brick colorants for the commercial and residential construction markets, red iron oxides enhance red tones when added to red and buff-burning ceramic bodies. Available in powder form, the oxides can be used as dry additives or customers can “just add water”™ to form a stable slurry for liquid dosing.
