| Abstract: |
| There are some disadvantages in the traditional chemical analysis methods for the determination of primary and secondary elements in ore, including time-consuming analytical process, low efficiency, big elemental interference which costs a lot of manpower and material resources. In this paper, the advanced inductively coupled plasma emission spectrometry technique was used to study the primary and secondary elements in manganese ore. Thirteen elements were mainly analyzed, which included aluminum, copper, calcium, iron, potassium, magnesium, manganese, sodium, nickel, phosphorus, titanium and zinc, etc. The working conditions were as follows: the radio frequency power of 1 150 w, atomizer velocity of 0.70 L/min, the auxiliary device velocity of 0.50 L/min and observation height of about 12 mm. Mineral samples were dissolved using nitric acid, hydrochloric acid, hydrofluoric acid and perchloric acid. The interference test showed that the determination of trace elements was not interfered when the concentration of coexisting elements such as potassium, sodium, calcium, magnesium, manganese and vanadium was below 200 mg/L in the solution. The detection limit of the method is about 0.0002%~0.0065% and the precision is less than 3.7%, which are consistent with the required precision and accuracy that are defined in the quality control standard for conducting test in a geology and mineral resources laboratory, namely, DZ/T0130—2006. |
