With reference to metals and their ores, which of the following pairs is INCORRECT?

Options

A. Gold (Au) - Calaverite
B. Mercury (Hg) – Greenockite
C. Aluminium (Al) – Cryolite
D. Cobalt (Co) – Smelite

Answer

B

Explanation

Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite or krennerite. Mercury is either found as a native metal (rare) or in cinnabar, metacinnabar, corderoite, living stoneite and other minerals. Greenockite is a rare cadmium bearing metal sulfide mineral consisting of cadmium sulfide in crystalline form. Major ores of aluminium are Bauxite, Corundum, Felspar, Cryolite, Alunite and Kaolin. Smelite is an ore of Cobalt.
