PYRITE ROASTING, AN ALTERNATIVE TO SULPHUR

2009-10-15  The roasting of sulphide ores and concentrates is often the first step in the production of metals or chemicals. In many processes, the production of sulphuric acid is viewed as a by-product, while in some plants production is an important economic factor. Regardless of the purpose, a pyrite roasting plant consists of mainly three plant sections: roasting, gas cleaning and sulphuric acid. With the addition of air, the pyrite

How is zinc produced? Nyrstar

2021-8-19  The produced calcine is dissolved in sulphuric acid during a process called leaching. In order to produce a very pure zinc sulphate solution, we separate a wide range of other metals during this step as well: lead, gold, silver doré, copper, cadmium and cobalt. The zinc sulphate solution consequently enters the stage of electrolysis: step three.

History, Deposits, and Production of Zinc

2020-3-30  At the same time, the sulfur combines with oxygen to form gaseous sulfur dioxide (SO2). Sulfuric acid is extracted from the sulfur dioxide in special plants - an important by-product of zinc extraction. Sulfuric acid is needed, for example, for the production of fertilizers. Zinc has a low melting point (419.53°C).
