Sallies was incorporated in 1903 as The South African Land and Exploration Company Limited to develop a gold mine on the East Rand. The bulk of Sallies acidspar output is exported to produce hydrofluoric acid (HF). This product is converted into HFC refrigerant gases, fluoroplastics, aluminium tri-fluoride and products for niche markets. Acidspar from Witkop is widely sought after due to the low levels of contaminants in its product. The Buffalo product contains a higher level of phosphorous and thus has a more restricted market.
