| titleOfInvention | A kind of determination method of vanadium pentoxide, copper, molybdenum, nickel and zinc in stone coal vanadium ore |
| abstract | The invention relates to the technical field of metallurgy and chemical industry, in particular to a method for determining the amounts of vanadium pentoxide, copper, molybdenum, nickel and zinc in stone coal vanadium ore; the method comprises the following steps: selecting a sample from stone coal vanadium ore, The sample is prepared into a stone coal vanadium ore sample; the stone coal vanadium ore sample is subjected to desiliconization, and after being extracted with nitric acid, the volume is fixed, and the supernatant liquid is taken to be tested; a blank test solution is taken, and the components to be tested include The analysis wavelengths of vanadium pentoxide, copper, molybdenum, nickel and zinc, the supernatant liquid and the blank test solution were detected with a measuring instrument, and the mass concentrations of the components to be tested in the stone coal vanadium ore sample and the blank test solution were detected respectively. , and according to the mass concentration of the components to be tested in the stone coal vanadium ore sample and the blank test solution, the analysis results of the sample measurement of each component in the stone coal vanadium ore sample are calculated. The purpose of the present invention is to solve the problem of low accuracy of component analysis of stone coal vanadium ore by the existing mineral analysis method. |
