The salt field operation at Walvis Bay comprises two companies, Salt & Chemicals (Pty) Ltd and Walvis Bay Salt Refiners (Pty) Ltd.

Salt & Chemicals produces the raw salt whilst Walvis Bay Salt Refiners further processes and markets the salt.

Both S&C and WBSR are Namibian registered companies and are wholly owned subsidiaries of Walvis Bay Salt Holdings (Pty) Ltd, which in turn is a wholly owned subsidiary of Chlor-Alkali Holdings (Pty) Ltd.

The salt field operation at Walvis Bay was established in 1964 and is one of the largest solar evaporation facilities in Africa, processing 24 million tons of sea water to produce in excess of 650 000 tons of high-quality salt per annum.

The bulk of the salt produced by Walvis Bay Salt Refiners is exported to markets in Southern and West Africa, where it is used mainly by the chlor alkali industry for the production of chlorine and caustic soda, by the agricultural sector as a feed supplement, as well as a feedstock for refined table salt for human consumption.
