    The main gas emission from the primary copper smelting is sulfur dioxide, which is treated, captured and recovered efficiently as sulfuric acid in modern copper smelting plants Kojo and Storch, 2006. As black copper smelting is almost sulfur-free process, the sulfur dioxide production is much less than in primary copper smelting.
