The valuable minerals are then separated from the rock using a variety of physical and chemical separation methods. People have extracted minerals, for example iron and copper, from ores for thousands of years. Examples of how minerals were mined long ago can be found at archaeological sites in South-Africa, such as Mapungubwe.

Another method to separate components of a mixture is based on melting point. The melting point of salt is 1474°F (801°C), while that of sand is 3110°F (1710°C). Salt becomes molten at a lower temperature than sand. To separate the components, a mixture of salt and sand is heated above 801°C, yet below 1710°C.

This method can be used to separate slightly larger pieces of dirt, stones and husk from the grains because the quantity of such impurities is usually not very large. 2. Sieving: Sieving is a simple technique for separating particles of different sizes. A sieve such as one used for sifting flour has very small holes.

Ore sorting in itself is not a new concept; it was introduced during the Stone Age with hand-sorting being the first method to separate valuable materials from gangue (Wills and Napier-Munn, 2006; Sassos, 1985). However, over the years the scale of mining has increased and hand-sorting has become challenging to implement (Joensson, 2014).
