Introduction. The use of Copper dates back far into history. Copper beads have been found in what is now modern Iraq, dating back to 9000 BC. The metal is relatively easy to mine and refine, contributing to its early and widespread use.
Solid metallic iron replaces the Cu2+ in the solution and becomes Fe2+. Solid metallic iron content can be determined by determining the Fe2+ content in the solution. The objective of this study is to develop an accurate method to determine the metallic iron content in the steel-making by-products, whereby this method can also be
