Zinc | Geology for Investors

Zinc is hard and brittle at most temperatures and has a relatively low melting point of 420°C. Zinc is just over seven times heavier than the same volume of water. Zinc is commonly found in association with copper and lead in various ores. The main zinc ore mineral is called sphalerite, which is a zinc sulphide. What Are The Main Uses For Zinc?
