    Study Notes

    Metallurgical Analysis

    • Metallurgical Analysis, also known as "Assaying", is the application of analytical-chemical methods to chemical problems of metallurgy, including valuation, utilization, and production.
    • It involves the quantitative estimation of metals in ores and furnace products, and the determination of all constituents (metallic and non-metallic) of ores and metallurgical products.

    Purpose of Metallurgical Analysis

    • The purpose of Metallurgical Analysis is to achieve targeted revenue and profit in a mine by ensuring both quantity and quality.
    • Assaying serves purposes beyond mining operations, including:
      • Estimating a material's commercial value
      • Determining a material's fitness or adaptability to a certain use
      • Guiding process operation or determining the efficiency of a process or treatment

    Selection of Assaying Method

    • Analysis can be made for either technical or commercial purposes.
    • The selection of an assaying method depends on the purpose, with a focus on:
      • Accuracy (desirable for some purposes)
      • Precision (required for specific time-based results)
      • Cost and material efficiency (important for approximations)
    • The most accurate method known should be applied when accuracy is the most important requirement, and should be carried out by skilled analysts.
