[The determination of high content tin in powder samples by line width method]

Area of Science:

• Analytical Chemistry
• Materials Science
• Geochemistry

Context:

• Accurate quantification of elements in mineral samples is crucial for resource evaluation and material characterization.
• Tantalum-tin minerals are valuable resources requiring precise elemental analysis.
• Spectral analysis methods are widely used for elemental determination in geological materials.

Purpose:

• To quantitatively determine the concentration of 60% tin (Sn) in tantalum-tin mineral samples.
• To investigate the influence of varying lead (Pb) concentrations as an internal standard on the accuracy and precision of spectral analysis.
• To establish optimal conditions for the line width method in analyzing tin in mineral matrices.

Summary:

• The study employed the line width method for the quantitative determination of 60% tin (Sn) in tantalum-tin mineral samples.
• The effect of different lead (Pb) concentrations (1%, 2%, and 3%) as an internal standard on analytical results was evaluated.
• Experimental findings indicate that the concentration of the internal standard element (Pb) critically affects both the accuracy and precision of the spectral analysis.

Impact:

• Provides insights into optimizing spectral analysis for tin and tantalum quantification in complex mineral matrices.
• Highlights the importance of internal standard selection and concentration control for reliable elemental analysis.
• Contributes to improved methodologies for geochemical exploration and metallurgical process control involving tantalum-tin ores.
