【 摘 要 】

One of the most common copper concentrate smelting furnaces is Flash smelting furnace which smelts over the half of the world's copper concentrates. The copper concentrate, air or oxygen enriched air and auxiliary fuel oil are charged into this furnace. Due to pyrolysis of copper concentrate, and reaction the decomposed products with oxygen intake, a large amount of heat release that causes the melting of copper concentrate. Since the copper concentrate, contains various minerals, and each of their reactions with atmospheric oxygen in the furnace creates certain conditions; by varying the percentage of minerals in the concentrate charged into the furnace, many problems are raised. In order to fix the problems, and also recognizing the proper actions at the time of changing minerals; within 6 months, inlet concentrate were mineralogically and chemically analyzed and the effect of concentrate minerals on-air and fuel consumption as well as the dust production were studied and The most appropriate concentrate which creates the best conditions in the Khatoon Abad Flash Furnace is obtained.
