sulphuric acid from copper production smelting

Copper Sulphuric Acid

2018-4-30 · Outokumpu flash smelting is a closed process which can achieve up to 99% capture of the sulphur-rich gases from the smelting furnace for the production of sulphuric acid. The technology was first introduced at Outokumpu's Harjavalta smelter in Finland in the late 1940's.

Suppressing SO 3 formation in copper smelting flue

2020-9-16 · SO3 in the copper smelting flue gas not only causes serious corrosion in heat exchange and dust collection equipment but also increases the amount of sewage acid (waste acid or polluted acid from copper smelting). In this study, we attempted to reduce the damage by ejecting pyrite into the flue to suppress SO3 formation in the flue. First, the Gibbs free energy for the chemical reactions
