· The economic advantage of sulphide ores lies in their amenability to concentration through flotation – a process whereby crushed ore is mixed with water to create a slurry. When agitated, chemicals are introduced which cause the sulphide minerals to become hydrophobic (water-repelling) and attach to air bubbles.

Ores also differ from minerals in terms of their physical properties. While minerals have specific physical properties that can be used for identification, ores may not exhibit such distinct characteristics. Instead, the value of an ore is determined by its chemical composition and the concentration of the desired element or mineral.
