Zinc Research Paper
Zinc is a lustrous bluish-white metal. It is brittle and crystalline at ordinary temperatures but it becomes ductile and malleable when heated between 110°C and 150°C. It is a reactive metal that can combine with oxygen and other non-metals and will react with dilute acids to release hydrogen.
Mostly zinc is used for galvanizing iron with more than 50% of metallic zinc goes into galvanizing steel and in the preparation of certain alloys. Then, zinc is added during industrial activities such as mining, coal and waste combustion and steel processing. Some soils are heavily contaminated with zinc, and these are to be found in areas where zinc has to be mined or refined, or were sewage sludge from industrial areas has been used as fertilizer.
