Savings in calcareous materials and coke and greater regularity in the operation of blast furnaces are additional advantages. Moreover, it makes an indirect contribution to purifying the smoke. Calcium chloride reduces the corrosion of the refractory linings caused by the acidity of the molten slag in the blast furnaces. For non-ferrous metals Calcium chloride is used as a chemical intermediary for the production of titanium oxide, as well as zinc and tungsten. In addition, mixed with sodium chloride, it lowers the melting point of non-ferrous ores.
Sodium carbonate is used in the precipitation of cobalt carbonate.
Various oxidants are used. It is also highly appreciated for the selective separation and purification of uranium salts. Sodium chlorate can also be used as a chemical oxidizing agent. Caro's acid makes it possible to purify cobalt by oxidizing it in an acid environment and separating it from other metallic ions, notably those of nickel and manganese. Foundry Sodium carbonate is used to produce bentonites, which in turn are used in foundries as an additive to the molding sands.
