To improve analysis speed in the determination of tungsten trioxide in geological samples, and simplify analysis process, based on potassium thiocyanate-titanium trichloride method, the mineral samples were dissolved with hydrochlo-ride, and nitric acid, and tungsten trioxide content in the sample was determined using this method, and verified with na-tional standard sample, and the test method was optimized.The determination data is stable and reliable with concise steps, and were in conformance with the results using the original method, meeting the requirement of batch test at laboratory. method in the analysis of rocks and minerals ( the 55.3.4 method) analysis of the results, can meet the requirements of la-boratory of geology Group bulk detection.
