Group 12 element by mass, and even the leanest concentrated deposits are at least 0.1% mercury (12,000 times average crustal abundance). It is found either as a native metal (rare) or in cinnabar (HgS), corderoite, livingstonite and other minerals, with cinnabar being the most common ore. While mercury and zinc minerals are found in large enough quantities to be mined, cadmium is too similar to zinc and therefore is always present in small quantities in zinc ores from where it is recovered. Identified world zinc resources total about 1.9 billion tonnes. Large deposits are in Australia, Canada and the United States with the
Wooden toymaking in the Ore Mountains Wooden toymaking in the Ore Mountains The history of wooden toymaking in the Ore Mountains is closely bound to regional circumstances. The Ore Mountains are located in Central Europe on the border between Germany and the Czech Republic.
