About Metal Recycling

 · When talking about scrap metal recycling, it is important to differentiate between the two main categories of scrap metal: ferrous metal, and nonferrous metal.While ferrous metal contains some degree of iron (and in fact, its name is derived from the latin term meaning iron), non-ferrous metal does not contain iron as a component.

What are Refractory Metals

Tungsten has the highest melting point of all metals. It also has one of the highest densities of all metals. When combined with carbon, it becomes one of the hardest man-made materials. While most people are familiar with tungsten filaments for light bulbs, its most common and most invaluable use is in metal cutting, mining and oil drilling tools.

Metallurgic Processes | Boundless Chemistry

After mining, large pieces of the ore feed are broken through crushing and/or grinding. This step creates particles that are either mostly valuable or mostly waste. Concentrating the particles of value in a form supporting separation enables the desired metal to be removed from waste products. Ore bodies often contain more than one valuable metal.
