| Abstract: |
| A new method for the determination of copper, lead, zinc, nickel, cobalt, cadmium, magnesium and manganese content in copper ore and tailing concentrate by inductively coupled plasma emission spectrometry was established. In this method, samples were digested in HCl-HNO3-HF-H2ClO4 solution. The optimized acid concentration, digesting condition, and interference of co-existing element were experimentally studied. The concentration ranges that can be analyzed for the elements were following: ω(Cu)：0.010%～2.50%，ω(Pb)：0.005%～1.00%，ω(Zn): 0.005%～1.50%，ω(Ni): 0.005%～0.05%，ω(Co)：0.005%～0.05%，ω(Cd)：0.005%～0.015%，ω(Mg)：0.010%～8.00%，ω(Mn): 0.005%～0.50%. By spike recoveries experiments, the recoveries were found as 83%~103%(n=3). This method is accurate and reliable and suitable for the determination of copper, lead, zinc, nickel, cobalt, cadmium, magnesium and manganese content in copper ore and tailing concentrate in the same time. |
