| Abstract: |
| The precisions of five analytical methods for the determination of Cu contents in copper magnetite samples were compared using F-test method based on GB/T 6739.6. The results indicated that there were significant differences among these five methods. A principle for the selection of analytical methods for Cu detection was given. |
