  • Chapter 9. Classification Wills' Mineral Processing

    The carrying fluid can be a liquid or a gas. In mineral processing, this fluid is usually water, and wet classification is generally applied to mineral particles that are considered too fine (<200 µm) to be sorted efficiently by screening. As such, this chapter will only discuss wet classification.

  • Mechanical screening Wikipedia

    Mechanical screening, often just called screening, is the practice of taking granulated ore material and separating it into multiple grades by particle size. This practice occurs in a variety of industries such as mining and mineral processing, agriculture, pharmaceutical, food, plastics, and recycling. A method of separating solid particles according to size alone is called screening.
