Recycling furnace for melting scrap aluminium. The metal melts at 660 degrees Celsius. A worker is controlling the process from a distance using a long rod while wearing overalls and a mask for protection from the intense heat. The molten metal will be made into ingots to be used to make new objects. Aluminium is a strong yet light, metallic element that is resistant to corrosion and is used extensively in industrial construction and also in household items. Purifying aluminium ore is a costly process, providing an economic incentive for recycling used aluminium.
