Collection and test of ore smelting test samples Before sampling, the sample design should be prepared in consultation with the test unit and the design and production department according to the test purpose and requirements. The collection of test samples at all stages of the laboratory is the responsibility of the survey unit. The surveying unit shall assist in the collection of semi-industrial test samples. The samples taken should be fully representative in terms of ore type, grade, material composition, structure and spatial distribution. Considering the depletion during mining, a certain amount of surrounding rock and stone can be incorporated, so that the grade of the sample is slightly lower than the average grade of the exploration area (segment). The test sample shall be taken according to the type and grade of ore, and the mixed test sample shall be taken according to the proportion of different ore types. The optional properties and beneficiation methods of powdered pyrite ore and primary ore are different, and the two cannot be mixed. When powdered ore pyrite Danfa Yu, should a separate sample to test. Test samples can be taken in tanks, wells, and tunnels. It can also be taken in the borehole under conditions without deep exploration. The sampling method mostly uses the whole lane method, the stripping method, the core sawing method, and the like. The quality of the test sample shall be agreed with the test unit according to the purpose of the test. A number of ore and the final product to be included in the analysis of total sulfur, available sulfur, total iron and iron oxide, iron oxide, and other ore characteristics and evaluation related projects; metals and sulfur content of a sample to be dressing Balance analysis.
