Evolving metal extraction processes

The metals industry has experienced transformational moments before: the Bessemer process, flash smelting, electric arc furnaces, and modern continuous casting all changed what was possible.Yet, for more than a century, most extraction processes rely on techniques and pathways that would be familiar to metallurgists from generations ago. Processes have become larger and control systems smarter, but the fundamental science behind separating metals from ores has changed less than many realize.Toda
