Zinc is a blue-white metal. The density is 7.14 g/cm3 and the melting point is 419.5°C. It is brittle at room temperature; it becomes soft at 100-150°C; it becomes brittle again when it exceeds 200°C. The chemical nature of zinc is lively. In the air at normal temperature, a thin and dense basic zinc carbonate film is formed on the surface to prevent further oxidation. When the temperature reaches 225 ℃, zinc oxidation is intense. When burning, it emits a blue-green flame. Zinc is easily soluble in acid, and it is also easy to replace gold, silver, copper, etc. from the solution. Zinc exists in the state of sulfide in nature. The main zinc-bearing mineral is sphalerite. There are also a small amount of oxidized ore, such as Rhodochrosite, such as Rhodochrosite and heteropolar ore.
