How salt is made - material, used, processing, procedure .

Salt is the common name for the substance sodium chloride (NaCI), which occurs in the form of transparent cubic crystals. Although salt is most familiar as a food supplement, less than 5% of the salt produced in the United States is used for that purpose. About 70% is used in the chemical industry, mostly as a source of chlorine.

This process is known as crystallization. The chemical elements within the magma or lava combine in specific ratios to form mineral crystals of various forms. Minerals form in water as precipitates. A precipitate is an insoluble solid that separates from a liquid solution. Also, when chemical elements dissolve in hot water, they form a solution.

The Extraction of Iron - Chemistry LibreTexts

The Extraction of Iron - Chemistry LibreTexts

Removal of carbon: The still impure molten iron is mixed with scrap iron (from recycling) and oxygen is blown on to the mixture. The oxygen reacts with the remaining impurities to form various oxides. The carbon forms carbon monoxide. Since this is a gas it removes itself from the iron! This carbon monoxide can be cleaned and used as a fuel gas.
