Chemicals and derivated products
Antimony can be found in nature, either in the form of oxides and sulfides, or in association with other metals. It is employed in alloys or in the form of oxides. It is mainly used as a flame retardant in textiles and plastics, or as a fining and decolouring agent in glass.
Umicore Precious Metals Refining has an annual production capacity of about 6,000 tonnes of sodium antimonate. It is produced as a dried or non-dried powder.
Sulphuric acid is produced from the sulphur contained in the raw materials we process. It is primarily used in the production of fertilisers, but also in the steel industry and various other applications.
Our yearly capacity is about 165,000 tonnes.
Aggregate for concrete
The slag, the remainder of our process, is used in the construction industry, e.g. as a substitute for gravel or sand in concrete, or in dyke fortification projects. Our products are sold under the brand names "Betozand" (0-4mm), "Betogrind" (4-32 mm) and "Umirock" (5-40kg, 10-60kg).
We have a CE & BENOR certificate for Betozand & Betogrind.
