Sulfuric acid is used in almost all industrial sectors. Typical areas of application are in the production of fertilizers and pigments as well as metal ore leaching. In addition, sulfuric acid is used extensively in the chemical industry, whether in fiber production, hydrofluoric acid production, chlorine drying or one of the many other applications.

Aurubis sulfuric acid is produced in our plants in Hamburg, Germany and Pirdop, Bulgaria. With an output of more than 2 million t, Aurubis is one of the largest producers and an important supplier to the global market.

Our customers appreciate our remarkably high degree of supply security.
Because our production facilities are equipped with extensive cleaning facilities, our products are regarded as being one of the best available qualities.

For particularly quality-conscious customers who specifically require low mercury levels, our premium quality  produced in our Hamburg plant with the use of additional cleaning processes is a very attractive option.
