chromite, which is the only ore for chromium, and they are the primary source for both high-chromium, low-aluminum ore, used in metallurgical applications, and high-aluminum, low-chromium ore, used in refractories (Thayer, 1946; Thayer, 1963; Dickey, 1975). Concentrations of chromite as

Beer's Law Definition and Equation - thoughtco.com

Beer's Law is an equation that relates the attenuation of light to properties of a material. The law states the concentration of a chemical is directly proportional to the absorbance of a solution.The relation may be used to determine the concentration of a chemical species in a solution using a colorimeter or spectrophotometer. The relation is most often used in UV-visible absorption ...

How Is Chromite Used? | Reference.com

Chromite, a mineral ore that is mined from crystallized magma, is used in the production of steel as a pigment and as a catalyst in many chemical reactions. It is also an important component of the leather tanning process. Chromite is also used to anodize aluminum for use in jet engines.

Chromium Compounds - US EPA

Chromium compounds, in either the chromium (III) or chromium (VI) forms, are used for chrome plating, the manufacture of dyes and pigments, leather and wood preservation, and treatment of cooling tower water. Smaller amounts are used in drilling muds, textiles, and toner for copying machines. (1) Sources and Potential Exposure

Mineral Processing Introduction - MetSolve Labs

Most rock deposits contain metals or minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or gangue material. Within an ore body, valuable minerals are surrounded by gangue and it is the primary function of mineral processing, to liberate and concentrate those valuable minerals.
