Chapter 2-Ore Handling. Ore handling is a key function in mining and mineral processing, which may account for 30–60% of the total delivered price of raw materials. It covers the processes of transportation, storage, feeding, and washing of the ore en route to, or during, the various stages of treatment in the mill.

Introduction. Milling, sometimes also known as fine grinding, pulverising or comminution, is the process of reducing materials to a powder of fine or very fine size. It is distinct from crushing or granulation, which involves size reduction to a rock, pebble or grain size. Milling is used to produce a variety of materials which either have end

· Introduction to Mineral Processing. Mineral processing is a field that contends with procedures and technologies used for separating valuable minerals from gangue or waste rock. It is a process that converts the extracted ore through mining activity into a more concentrated material, which serves as an input for the extractive metallurgy.

The mineral is usually transferred to the froth leaving behind the gangue in the pulp. This is termed as direct flotation. However, during reverse flotation the gangue is separated into the float fraction while the valuable mineral is retained in the pulp. The process can only be applied to relatively fine particles.
