| 제목 | An Aspen Model for the atmospheric acid leaching of nickel-copper matte |
| 초록 | The note summarized in this paper deals with modeling and simulation of atmospheric leaching process of nickel-copper matte. Computer simulation is a cost effective means of examining how the process is affected by using certain quantities of chemicals, varying flow rates, and varying operating conditions. To understand the nature of the leaching process during the stage of operation, the leaching mechanism of the matte is explained. Through simulation the effects of different parameters on nickel leaching were investigated, mainly operating temperature, and acid concentration. The modeling of this process was performed on a computer simulation package known as Aspen Plus. Under atmospheric pressure 68.8% of nickel, 14.05% of iron, 24.92% of copper, 10.66% of cobalt and 4% of zinc are extracted under suitable conditions of sulfuric acid concentration and reaction temperature.
