From Ore to Ingot: The Transformation of Metals
The acquisition of metals begins with the excavation of raw material. This rich deposit contains minute quantities of metallic elements that need to be separated. The initial step in this transformation is pulverizing the ore into a fine powder. This minutely ground ore then undergoes several stages to finally yield a concentrated metal {ingot|. The specific procedures employed vary depending on the type of metal being processed, but generally involve smelting the ore in the presence of chemicals to isolate the desired metal. This molten metal is then cast into molds, resulting in the final product - a refined ingot ready for further transformation.
