Chemical grade chromite
Chemical grade chromite is not only used in leather tanning, metal finishing and wood preservatives but also in the production of light-stable and corrosion inhibiting pigments in addition to paints, colored glass and ceramic glazes. Common chromium chemicals: Potassium dichromate, sodium dichromate , Chromium trioxide and chromium oxide green.
The chemical grade chromite ores are used extensively for the production of sodium chromate. The mineralogical properties, which pose a major limitation in utilising a wide variety of chemical grade chromite ores from different origins, determine the yield of sodium chromate in the soda-ash roasting process.
SICHENG focus is on supplying chemical grades chromite of South African origin with the following characteristics:
– Cr2O3 min. 45 % or min. 46 %
– SiO2 max. 1.2 % or max. 1.0 %
– Sizing typ. 95 % < 1.0 mm
– wet or dry
Chemical grades chromite can be shipped loose in bulk or packed in big bags, in both FCL’s and bulk carrier loads, depending on customer’s requirements.
