The Latin term, during the Roman Empire, was aes cyprium; aes was the generic term for copper alloys such as bronze. Cyprium means "Cyprus" or "which is from Cyprus", where so much of it was mined; it was simplified to cuprum and then eventually Anglicized as "copper" (Old English coper/copor). · Symbol Cu is from the Latin name cuprum ("copper").
Recycling codes on products. Recycling codes are used to identify the materials out of which the item is made, to facilitate easier recycling process.The presence on an item of a recycling code, a chasing arrows logo, or a resin code, is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of.
118 chemical elements have been identified and named officially by IUPAC.A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z).
Iron and steel are the world's most recycled materials, and among the easiest materials to reprocess, as they can be separated magnetically from the waste stream. Recycling is via a steelworks: scrap is either remelted in an electric arc furnace (90-100% scrap), or used as part of the charge in a Basic Oxygen Furnace (around 25% scrap). [20]
The term "ferrous" is derived from the Latin word meaning "containing iron". This can include pure iron, such as wrought iron, or an alloy such as steel. Ferrous metals are often magnetic, but not exclusively. Non-ferrous metals and alloys lack appreciable amounts of iron.
The more frequently recycled metals are scrap steel, iron (ISS), lead, aluminum, copper, stainless steel, and zinc. Steel [9] is the most recycled due to its sustainable properties. There are two main categories of metals: ferrous and non-ferrous. Metals that contain iron in them are known as ferrous. Metals without iron are non-ferrous.

Planetary names and symbols for the metals – the seven planets and seven metals known since Classical times in Europe and the Mideast – was ubiquitous in alchemy. The association of what are anachronistically known as planetary metals started breaking down with the discovery of antimony, bismuth and zinc in the 16th century.
