The invention discloses a quantitative determination method for trace harmful elements in flotation products of rare polymetallic ore. The quantitative determination method comprises three parts of sample treatment, complex matrix standard solution preparation and sample testing. Digesting each flotation product with analytically pure concentrated nitric acid; determining the types of main minerals of each product by virtue of XRD (X-Ray Diffraction), digesting a high-purity standard substance of each main associated mineral by virtue of analytically pure concentrated nitric acid, moderately diluting, and determining the content of harmful elements to be monitored by virtue of ICP-MS (Inductively Coupled Plasma Mass Spectrometry); diluting each standard substance digestion solution until the main element concentration is 1000 [mu] g/mL, and diluting the harmful element standard stock solution by using the standard substance digestion solutions to obtain standard solutions with different concentration gradient
