Chemplex Corporation entered the Zimbabwean scene in 1924 when AE&CI, a South African company then owned in equal shares by De Beers Consolidated Mines Limited and Nobel Industries Limited, opened a Sales and Distribution office in Bulawayo to supply the mining industry with explosives, sulphuric acid, and hydrochloric acid among other products. In those days Nobel used to make hydrochloric acid by mixing sulphuric acid with salt. AE&CI had a solid reputation for maintaining a Chemical Services Department, staffed by qualified and experienced industrial chemists, to provide free technical advice and assistance in connection with the chemicals sold by the Company. Chemplex Corporation has proudly nurtured this reputation throughout the years. In 1990 AECI sold Chemplex Corporation a wholly owned Zimbabwean company.Chemplex Corporation has five main operating divisions - Dorowa Minerals, Zimbabwe Phosphate Industries Limited (ZimPhos), Chemplex Marketing, Chemplex Animal and Public Health (CAPH), and G. D. Haulage. ZimPhos is the country\'s sole producer of sulphuric acid, aluminium sulphate (used in municipal water treatment), and superphosphates (used in the manufacture of phosphatic fertilisers)
