Sodium chlorate use in Mining: Oxidant in uranium extraction
Other uses: Oxidising agent; food preservative; soap manufacture; water softener; de-icing agent; photography; herbicide; manufacture of pulp bleaching chemicals.
Sodium chlorate is a strong oxidizer that has applications as an herbicide and in the mining industry. Sodium chlorate was traditionally the first choice oxidant in North American uranium plants. It is clear that each mole of sodium chlorate requires 3 moles of acid. In Southern Africa sodium chlorate was not considered as an oxidant due to availability of cheaper and more convenient alternatives (i.e. pyrolusite).
Sodium chlorate is added to the leach slurry as a solution. No special agitation is therefore necessary. During the reaction with sodium chlorate in the leach, chloride ions go into solution with the possible adverse effects on ion exchange loading and materials of construction.
It is also used as oxidant in PGM refining. Partial reduction leads to intermediate products, such as chlorite and hypochlorite. Sodium chlorate powder has an auto-ignition risk when in contact with organic. It therefore needs procedures and proper engineering for safe handling.
Other Sodium chlorate uses: fireworks, explosive, match and dyes.
