1905 1911 Chromite ore processing begins in Hudson County. With its proximity to one of America's busiest ports, Hudson County becomes a center for chrome production because most of the world's chrome reserves are located outside the United States.
In methods for treatment of in ground chromium ore processing residue contamination, ferrous sulfide is provided as a substantially insoluble material in the residue deposit. The ferrous sulfide accordingly may remain substantially in place, in the pores of the soil or residue, even over long periods of time, regardless of underground water movement or diffusion.
Chromium has a wide variety of applications in the modern world. Its major uses are in stainless steels and the plating of metals. Other important uses include alloy steel, heating elements, pigments, leather processing, catalysts, and refractories.
