Sensor-based sorting, is an umbrella term for all applications in which particles are detected using a sensor technique and rejected by an amplified mechanical, hydraulic or pneumatic process. The technique is generally applied in mining , recycling and food processing and used in the particle size range between 0.5 and 300 mm (0.020 and 11.811 ...
In the mining sorting industry, color sorting is also called sensor-based sorting technology. Optical color sorters (CCD color camera) combine X-ray sorting technology and NIR (near infrared spectrometry) to pick out the impurities of ore, minerals, stone and sand products, or separate ore into two or more categories.
Optical sorting (sometimes called digital sorting) is the automated process of sorting solid products using cameras and/or lasers.. Depending on the types of sensors used and the software-driven intelligence of the image processing system, optical sorters can recognize an object's color, size, shape, structural properties and chemical composition.

Also new sensors have been developed which exploit material properties such as electrical conductivity, magnetization, molecular structure and thermal conductivity. Sensor based sorting has found application in the processing of nickel, gold, copper, coal and diamonds.
TOMRA's sensor-based sorting technology business was first established in 2004 with the acquisition of TiTech Visionsort AS, a provider of optical recognition and sorting technology [9] (which was renamed to Tomra Sorting Solutions in 2012 [10]), from Ferd AS for 219 million NOK.
More generally objects can be sorted based on a property. Such a component or property is called a sort key. For example, the items are books, the sort key is the title, subject or author, and the order is alphabetical. A new sort key can be created from two or more sort keys by lexicographical order.
