Copper smelting apparatus and copper smelting method

摘要

Problem to be solved: to produce hydrogen using the sulfuric acid production process in the copper smelting process.The copper smelter 1 comprises a copper smelting device 11, a first reaction device 21 and a second reaction device 31.The copper smelter 11 melts the copper concentrate r to produce a coarse copper RC.The exhaust gas (high-temperature sulfur gas HS) of the copper smelter 11 contains sulfur dioxide.The sulfur dioxide is supplied to the first reaction device 21.The first reaction device 21 reacts water, iodine and sulfur dioxide to generate hydrogen iodide and sulfuric acid.The second reaction device 31 decomposes the hydrogen iodide to generate iodine and hydrogen.Diagram
