In metallurgy, non-ferrous metals are metals or alloys that do not contain iron (allotropes of iron, ferrite, and so on) in appreciable amounts.. Generally more costly than ferrous metals, non-ferrous metals are used because of desirable properties such as low weight (e.g. aluminium), higher conductivity (e.g. copper), [1] non-magnetic properties or resistance to corrosion (e.g. zinc).

Shenzhen Zhongjin Lingnan Nonfemet Co., Ltd. known as Zhongjin Lingnan in China or their English name Nonfemet (abbreviation of non-ferrous metal), is a Chinese company engaged in the mining and processing of lead, zinc and other non-ferrous metals. [3] In 2015 financial year, the company also had 0.49% revenue from real estate development. [2]
Non-ferrous extractive metallurgy is one of the two branches of extractive metallurgy which pertains to the processes of reducing valuable, non-iron metals from ores or raw material. [ 1 ] [ 2 ] [ 3 ] Metals like zinc , copper , lead , aluminium as well as rare and noble metals are of particular interest in this field, [ 1 ] while the more ...
Non-ferrous metals typically separated by an ECS include aluminum, copper and die-cast metals. [1] In waste sorting of single-stream recycling at materials recovery facilities, ECS is used after the waste has passed through some arrangement of magnets to remove ferrous metals. Eddy current separators are typically used at the end of the waste ...

It was founded in 1949 in Tongling, Anhui, China and it was put into production in 1952. It is one of the largest copper smelting companies in the country. [3] [4] [5] [6]
Horizontal converters of the Peirce-Smith type (which are an improvement of the Manhès-David converter ) prevail in the metallurgy of non-ferrous metals. Such a converter is a horizontal barrel lined with refractory material inside. A hood for the purpose of the loading/unloading operations is located on the upper side of the converter.
