Separation. Ore can be separated from other rock material by floatation. This is a process where the ore is first crushed and mixed with another substance such as an oil. This process is most commonly used to concentrate copper ores. The oil binds around copper minerals, making them repellent to water – a state known as ‘hydrophobicity’.
