McLanahan | Ore Washing and Machine Selection
The term "washing" can be defined as "removing a substance by or as by the action of water". In a mineral processing sense, washing commonly refers to the removal of loosely attached particles — often fine clays — from the surface of more competent ore. In this definition, washing is distinct from classification, which would be a ...
