Zinc Case Study

Zinc is a wonderful choice to produce coinage since it is an abundance element with stable market pricing contrasted with numerous other coinage elements. In addition, they require less plating than other alternative base metals and its transportation cost are lower as well. Zinc comes in a phase of a solid with blueish-white color that exhibits a shiny luster and are neither ductile or malleable at room temperature unless the metal is being heated. One of the most important quality of zinc is its ability to resist corrosion and protect other metals. Other noticeable property of zinc is its electrical conductor ability that will conduct with dilute acids to release hydrogen. In order to prevent people from counterfeiting the coin, the coin itself needs to have a distinguishable design and a distinct cut edges of the coins.

For the electrolytic production of zinc, the roasting of concentrating is achieved in fluidized-bed roasters, in which the divided and heated particles of concentrate are suspended in a rising stream of air. The sulfur content can be reduced to less than 0.5 percent, and a high-strength of sulfur dioxide gas is forwarded to a sulfuric acid plant. The process is thermally efficient, and the resulting calcine is in the form of small particles that can easily be leached into solution for further treatment. Therefore, using pure zinc metal is a good choice even with the disadvantage of the metal reactivity. Due to its abundant resources, zinc can be mined in six different states and 76 percent of refined zinc is imported to the United States from Canada, Mexico, Kazakhstan, and South
