Sorting - Wikipedia

Various sorting tasks are essential in industrial process For example, during the extraction of gold from ore, a device called a shaker table uses gravity, vibration, and flow to separate gold from lighter materials in the ore (sorting by size and weight) Sorting is also a naturally occurring process that results in the concentration of ore or sediment...
