Drying Basics and Principles
•I Preheating period – drying rate is slowly increasing – only a very slight change in MC •II Constant-rate period – drying rate is constant in time – removal of surface water – grain temperature is constant – energy usedt td to evaporate water •III Falling-rate period – drying rate declines over time -> Temperatures for drying

Milling is one of the most costly parts of beneficiation, and results in very fine particles that allow better extraction of the metal. However, milling also allows a more complete release of contaminants when these particles become tailings. Tailings are what remains following milling of the ore to fine particles and extraction of
