  • Since there are many kinds of non-ferrous metal, it is difficult to investigate the current status on the recycling of all the non-ferrous metals. Therefore, the survey is confined to some commercially important non-ferrous metals such as copper, aluminum, zinc, lead, nickel and magnesium in this article. Domestic demand and production of these non-ferrous metals in recent years (2010-2014) and recycling ratio of the scraps are estimated briefly here.

  • It is very necessary for the metal recycling industries and the researchers to understand the current status of demand and supply of non-ferrous metals and their scraps. Domestic demand and supply of non-ferrous metals and their scraps have been surveyed and reported on the journal of the Korean Institute of Resources Recycling since ten years before. However, it was confined to six major non-ferrous metals such as copper, aluminum, zinc, lead, nickel and magnesium because there are so many kind of non-ferrous metals. In this article also, demand and supply of these non-ferrous metals in addition tin during recent five years (2014 ~ 2018) in Korean markets were reviewed, and their recycling ratio of scraps were briefly estimated. The statistical data were mainly cited from the data issued by Korea Customs Service (KCS) and Korea Non-Ferrous Metal Association, and some fragmental published review articles from magazines and other technical reports.

  • Lead is one of the common non-ferrous metals used in modern industry. The usage of lead continues to increase and has risen from 5 million tonnes per year worldwide in the 1970s to 11 million tonnes in the 2010s. In principle lead is virtually 100 % recyclable as an element without loss of quality. The recycling of lead scrap reduces the energy consumption and environmental burden, comparing to the primary metal production. Therefore production of secondary lead from scrap has been steadily growing and at present it meets approximately 60 % of usage worldwide. Lead scrap (mainly lead-acid battery) is smelted in primary and secondary smelter. Most secondary lead smelting were performed in a shaft-type furnace (blast furnace), rotary furnace and reverberatory furnace. The lead bullion is either cast into ingots and re-melted in refining kettles or refining is performed on the hot lead bullion immediately after production. This work provides an overview of the primary lead production and recycling process.
