Embodiment Construction
[0027] Such as figure 1 As shown, the composition determination of niobium-tantalum ore can be carried out through the following steps:
[0028] 1. Determine the target element;
[0029] 2. Selection of reference materials;
[0030] 3. Optimize the fusion sample preparation procedure;
[0031] 4. Preparation of standard samples;
[0032] 5. Matrix and spectral line overlap correction;
[0033] 6. Actual sample verification: After the verification, the sample meets the requirements, and then it is put into production application; if the verification does not meet the requirements, the matrix and spectral line overlap correction is performed again until the requirements are met.
[0034] Carry out the following specific determination steps according to the above-mentioned basic process:
[0035] First, select niobium-tantalum ore standard substance GBW07154, rare earth ore standard substance GBW07184, GBW07185, vanadium-titanium magnetite tailings standard substance YSBC197...
