Color separators are used to separate ores in ore factories

Ore particle sorting has been used since the manual mining period. High quality ores are selected by manual sorting for smelting to optimize the quality and volume of final mineral products (Agricola, 1556). In modern times, mining companies have found a way to automate this process by using physical properties such as density (such as heavy medium separation process).

In the electronic age of modern science and technology, sensors were initially operated by logic controllers and paddles or other mechanical devices in order to physically separate individual particles. However, due to the limited output of these machines, they are generally used for special purposes. Up to now, with the progress of computer technology and the use of precision high-pressure jets, the throughput of the color sorter has reached more than 400 tons / hour.
