Zinc
Zinc is a lustrous, bluish-white metal. It is brittle at room temperature, but becomes malleable when heated to 100 degrees Celsius. It is mildly reactive with air, acids and alkalis. Zinc is a very useful metal, and used to plate iron, and protect it from corrosion, in a process known as galvanization. Zinc also is used in many other alloys ...

ore
Iron ore should contain about 30 percent iron if it is to be mined profitably. Gold ores containing as little as 0.044 ounce (1.25 grams) of gold per ton can be mined at a profit. Magnesium can be removed from sea water at a profit by special methods. Gold, though present in sea water, cannot yet be extracted profitably.

Zinc in nature
Zinc is constantly being transported by nature, a process called natural cycling. Rain, snow, ice, sun and wind erode zinc-containing rocks and soil. Wind and water carry minute amounts of zinc to lakes, rivers and the sea, where it collects as sediment or is transported further. all contribute to the continuous cycling of zinc through nature.
