Concentration ore refers to the process of removing matrix or gauge from an ore. Occurrence of Metals Some elements, such as carbon, sulphur, gold, and noble gases, are found in their free state in the earth's crust, while others are found in mixed forms. The amount of elements varies. The most plentiful metal on the planet is aluminium.

Metal ores are, on average, heavier than gangue particles. This feature is used in the gravity separation process to concentrate ore. The gravity separation technique is used to concentrate hematite ore. Iron oxide ore hematite is a common resource. Fe2O3 is the chemical formula for hematite. The ore of hematite is black or silver-grey in colour.
