Thereafter, the production route is less dependent on the original sulphur source, even though there are several processes for the conversion and the absorption stage (BAT N° 3, 1995). Approximately 0.33 t brimstone, 0.76 t pyrite (48 % S) or 1.2t zinc ore is typical raw material input for the production of 1t sulphuric acid (100%) (UNEP, 1996).

PYRITE ROASTING, AN ALTERNATIVE TO SULPHUR BURNING
Pyrite roasting and sulphur burning plants are built for the production of sulphuric acid. Whereas the burning of elemental sulphur is the main source for sulphuric acid, the roasting process is an interesting alternative once pyrite concentrate is available. In addition to these two applications, Figure 1 shows a wider variety of sources for the

Lead and Zinc Smelting IFC
Zinc Manufacturing. In the most common hydrometallurgical process for zinc manufacturing, the ore is leached with sulfuric acid to extract the lead/zinc. These pro-cesses can operate at atmospheric pressure or as pressure leach circuits. Lead/zinc is recovered from solution by electrowinning, a process simi-lar to electrolytic refining.
Sulfuric acid: Pumping up the volume
But in 1875, a contact-process acid plant was started up at Freiberg in Germany, using lead-chamber sulfuric acid decomposed by heat as a source for pure sulfur dioxide. From the mid-1880s on, the output of acid produced by the contact process grew rapidly. By then, gases from pyrites had replaced sulfuric acid as a source of sulfur dioxide.

SULFURIC ACID
The acid is used as a solvent, a dehydrating agent, a reagent in chemical reactions or process as catalyst, an absorbent etc. Source of sulphuric acid may be iron pyrites (35%), sulphur (46%), the waste gases of non ferrous metallurgy (15%) and hydrogen sulphide (4%). Sulphuric acid is one of the most important basis chemicals during war place.

Introduction to Sulphur The Sulphur Institute
Well over half of global sulphuric acid production comes from burning elemental sulphur at points of consumption, with most of the remainder produced at non-ferrous metals smelters and pyrites mines. East Asia, led by China, is the largest overall acid producer, stemming largely from rapid growth.
Sulphuric Acid Production nawabi.de
The output of sulphuric acid at base metal smelters today represents about 20% of all acid production. Whereas in 1991 smelter acid production amounted to 27.98 millions tonnes, it is calculated that the output in the following decade will have grown to reach 44.97 millions tonnes in 2001.
Sulphuric Acid an overview ScienceDirect Topics
Sulfuric acid (H 2 SO 4) is important in the production of fertilizers (e.g., ammonium sulfate (sulfate of ammonia), (NH 4) 2 SO 4, and superphosphate, Ca(H 2 PO 4) 2, which is formed when rock phosphate is treated with sulfuric acid). Sulfuric acid is manufactured at the site using the well-known contact process.

Sulfuric acid history ML2R consultancy
Apr 26, 2017 Sulphuric acid (American English: Sulfuric), H 2 SO 4, is a strong mineral acid.It can form any concentration in water. The old name for sulphuric acid is oil of vitriol. When high concentrations of SO 3 are added when making the acid, a solution of SO 3 in H 2 SO 4 results. This is called fuming sulphuric acid or Oleum or Nordhausen acid.
