Water is essential to mineral processing. It is used in various steps in the process to recover valuable metals from ore. The water use is quite high - for example, around 1600 litres of water are used to obtain the 19 kilograms of copper found in a medium-sized family car. Water is not always readily available for processing operations.

Once the ore is on the surface, the process of getting the mineral you want out of the rock can start. Once the mineral is separated from the rest of the rock, the mineral needs to be cleaned so that it can be used. This process can be represented by the following flowchart diagram: In this chapter we will look at each of the steps in more detail.
