Metallurgical engineering is a branch of engineering that deals with the study of metals and their properties, as well as the processes used to extract, refine, and manufacture metals and metal-based products. It encompasses a wide range of topics, including mineral processing, extractive metallurgy, physical metallurgy, materials science, and manufacturing processes. Metallurgical engineers use their knowledge of metals and materials to design and develop new products, improve existing products, and optimize manufacturing processes. They also use their expertise to troubleshoot problems in existing products and processes, and to develop new technologies and processes for the production of metals and metal-based products.
