Summary After reporting on the characteristics of sponge iron and the status of older production methods, this article has presented a description of the development of the Phelps Dodge Sponge Iron Process. The sequence of steps to produce sponge iron from copper-iron matte was detailed, emphasizing the ramifications of operation rather than theoretical aspects. Full-scale continuous operation of the enlarged Sponge Iron Dept. at Phelps Dodge should produce precipitant for copper “cementation” processes at a cost comparing profitably with the price of shredded de-tinned cans, with superior reactivity and lesser handling expense.

Summary and Conclusions The experimental results presented in this report illustrate the practical usefulness of the spectroscopic method. The spectroscopic analysis of defect-echoes yields more information on the defect configuration than available from ordinary pulse-echo test techniques. Thus, serious errors with regard to defect size can be avoided. Ultrasonic spectroscopy also affords a new and more effective approach to ultrasonic attenuation testing and can be used to sort steel according to grain size.
