The 12th group of the periodic table contains the elements zinc , cadmium and mercury and the element 112 copernicium , which was first produced in 1996 . Zinc occurs with a relative abundance of 7 × 10 −3 % in the earth's crust, cadmium with 2 × 10 −5 %. The group is often referred to as the zinc group or the 2nd subgroup (according to CAS as IIB). The elements of the zinc group often occur as sulfides. One then also speaks of zinc blends . To extract the elements, the sulphides are first roasted , then reduced with carbon and finally distilled .
