Method for simultaneously determining contents of arsenic, lead, zinc, calcium, magnesium and aluminum in gold-copper concentrate by ICP-OES (Inductively Coupled Plasma-Optical Emission Spectrometry) method

The invention discloses a method for simultaneously determining the contents of arsenic, lead, zinc, calcium, magnesium and aluminum in gold-copper concentrate by an ICP-OES (Inductively Coupled Plasma-Optical Emission Spectrometer) method, and belongs to the technical field of metal ore sample detection and analys.The method comprises the following steps: accurately weighing 0.1000 g of gold-copper concentrate sample in a 50mL digestion tube, adding nitric acid-hydrochloric acid-hydrofluoric acid, and digesting the gold-copper concentrate sample at a proper temperature; after complete digestion, opening a digestion cover, driving hydrofluoric acid, fixing the volume of the solution into a 100mL volumetric flask by using 10% diluted hydrochloric acid after the sample is cooled, and uniformly shaking for detection. According to the method, a standard curve is established by adopting a national standard reagent, and the contents of arsenic, lead, zinc, calcium, magnesium and aluminum in the gold-copper concentr
