| Abstract: |
| The gold concentrate samples were dissolved with HCl-HNO3 mixed acid and determined by ICP-OES. Under the selected operating conditions, the detection limit of arsenic is 0.018μg/mL. The relative standard deviation (n =11) was less than 2% RSD and the recovery was between 98.2 % and 103.0%. Using this method to determine arsenic content in gold concentrate is easy to operate and can meet daily production needs. |
