Refraction of Metal. Why Scrap is a Valuable Resource for the Future?

Have you ever wondered why we talk about the Bronze Age, and not, say, the Age of Agriculture or the Age of the Wheel? The answer is simple: metals have always been more than just materials. They are catalysts for change, engines of progress, defining the strength and possibilities of entire civilizations. Open this book — and you will enter a wonderful world. You will learn that it was metals that allowed people to build cities, create weapons and tools, and discover new lands. Remember the periodic table: each metal is a separate chapter in the development of civilization, from soft tin and lead to strong iron and titanium, without which neither space ships nor modern cities are possible.
