| titleOfInvention | A kind of detection method of gold content in molybdenum concentrate |
| abstract | A method for detecting gold content in molybdenum concentrate belongs to the technical field of mineral analysis and testing. The technical problems to be solved by the present invention are accurate and reliable detection results, simple operation and low cost. In the present invention, a sample of molybdenum concentrate is weighed, roasted at a low temperature in a muffle furnace, taken out and transferred to a polytetrafluoroethylene beaker to dissolve the sample, and after cooling, deionized water is added to rinse the inner wall of the beaker, to obtain a mixed solution, add lead acetate, and then Add perchloric acid, boil until thick smoke of perchloric acid is emitted, add deionized water after cooling to rinse the inner wall of the beaker, then add aqua regia, boil and cool to get the mixture and transfer it to a triangular flask, control the acidity, add foam plastic, shake to enrich Collect, take out the foam, wash it, press dry, put it into a colorimetric tube, add an appropriate amount of thiourea solution to boil to dissolve, take out the foam while hot, cool the solution, measure the absorbance of gold with an atomic absorption spectrophotometer, and calculate the gold content . The detection result of the invention is accurate and reliable, and the operation is simple. |
