Nickel-copper matte leaching process under atmospheric conditions |
| 초록 |
Nickel-copper mattes are conventionally treated by pyrometallurgical method, later the hydrometallurgical processes have gained an advantage over the conventional one by recovering valuable metals and reducing the environmental impact of industrial activities related to the processing of nickel ore deposits. As a mean of getting insight in the progress of a chemical process, computer simulation is a cost effective mean through which the effects of process variables such as flow rates and operating conditions variations can be assessed at the design phase. This study case deals with modeling and simulation of atmospheric leaching process of nickel-copper matte. To understand the nature of the leaching process during the stage of operation, the leaching mechanism of the matte is explained based on chemistry. Through simulation the effects of different parameters on nickel leaching process were investigated, mainly operating temperature, and acid concentration. The modeling of this process was performed on a computer simulation package known as Aspen Plus. |
