What is the chemical process of changing clay or other minerals to meet specific performance levels called?

• A. Calcination
• B. Purification
• C. Ion exchange
• D. Beneficiation

Answer: (D)

Beneficiation is the process of upgrading minerals to meet specific performance specs. It covers the range of methods used to improve the quality or behavior of clay or other minerals, often by removing impurities, altering particle size or dispersion, and sometimes modifying surface properties so the material performs as required in its application. This broad approach fits the idea of changing materials to meet target performance levels. Calcination is a heating step that drives off moisture or induces phase changes, but it’s a specific treatment rather than the general concept of upgrading minerals. Purification refers to removing contaminants, which is part of beneficiation but narrower in scope. Ion exchange is a particular chemical treatment exchanging ions to change properties, also more limited than the overall idea of improving material performance.
