Abstract:

One of the most common copper concentrate smelting furnaces is flash smelting furnace, which smelts over 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 the reaction of decomposed products with oxygen intake, a large amount of released heat causes the melting of copper concentrate. The copper concentrate contains various minerals, and each of them has various reactions with atmospheric oxygen in the furnace. Thus, each mineral generates a certain amount of dust. One of problems in flash furnace is dust generation, as dust is an environmental pollutant. In order to fix or improve the problem, it is necessary to recognize the proper actions at the time of feeding; within 12 months, inlet concentrates were mineralogically and chemically analyzed, and the effect of concentrate minerals on air and fuel consumption as well as the dust generation were studied. Subsequently, the most appropriate mineral in the concentrate which generates the least dust in the Khatoon Abad Flash Furnace is obtained.
