Where is gold usually found?

Gold is primarily found as the pure, native metal. Sylvanite and calaverite are gold-bearing minerals. Gold is usually found embedded in quartz veins, or placer stream gravel. It is mined in South Africa, the USA (Nevada, Alaska), Russia, Australia and Canada.

Which country has the cleanest coal?

RussiaAnthracite is found on the east coast in the US, South Africa, Australia, Western Canada, China and Russia. Two-thirds of Russia’s coal reserves are anthracite. Because of its efficiency and thus less carbon and sulphur usage per watt of power, anthracite is also the ‘cleanest’ coal in the world.
