Low turbidity chromite sand is chromium-based casting sand. It works as molding sand for lost casting, V-method casting, no-back sand casting, etc. Chromite sand used for casting is clean and of few silica impurities. By water washing and magnetic removal process, we remove harmful silica minerals from the sand.
