This article describes the evolution of ore jigging up to the early 20 century. Hand jigging with the use of sieves has been known since the 16 century. Fine comminution with sludge separation dominated ore processing in the 16–18 centuries. The first mechanical jigs of the late 18 century were equipped with movable sieves and had been subject to structural …

For example, a sample of ore might be crushed so that it all passes a 20-mesh sieve. The material is then separated by panning or by decanting under definite and controlled conditions into sand and slime fractions. Each fraction is weighed and assayed. Another sample of the ore might be ground to pass 65 mesh, and a similar separation …
