than 1 4-inch particle size fine slag. Fine slag dust can be a potential health risk when inhaled. Slag including fine slag may have migrated off the railroad bed into the surrounding right of way as a result of over 100 years of transportation activities. This work plan addresses consolidation of slag
The majority of TiO 2 is used in paints and coatings, plastics, and paper. There are few suitable pigment substitutes to TiO 2 due to its optical properties. Other uses for TiO 2 include food, pharma, cosmetics, textiles, electronics, ceramics, and construction materials. Titanium dioxide is also used as a feedstock

May 04, 2021 Pig iron is produced as a co-product of the smelting process. A roast-leach process is used to produce vanadium pentoxide V2O5 from vanadium slag. Vanadium pentoxide is then fed into an aluminothermic reduction to produce the final product, ferrovanadium FeV80. Possible by-products include sodium sulphate, TiO2 slag and Ca-Al Slag.
Another possibility is to smelt the ilmenite in electrical furnace to produce cast iron of special quality and TiO 2-slag. This treatment is well known as Sorel Process. One plant in Canada and another in South Africa use this process successfully. A plant of similar process is under construction in Norway.
Jul 13, 2010 Titanium dioxide is a photocatalytic material that grabs airborne nitrogen oxides and converts it to harmless nitrates with the help of the sun, and it is washed away by the rain. In addition, the mixed material breaks down dirt and algae, so it is sure to stay clean.
