Nonferrous metal Wikipedia
In metallurgy, nonferrous 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, nonferrous metals are used because of desirable properties such as low weight (eg aluminium ), higher conductivity (eg copper ), [ 1 ] non magnetic properties or resistance to corrosion (eg zinc ) Collon, P, Fabriol, R, Bues, M (2002) Chemical changes in groundwater due to flooding of an iron mine in a nonacid producing environment In 7th International Symposium on Environmental Issues and Waste Management in Energy and Mineral Production (SWEMP) (pp 761–768) Google ScholarManagement and Treatment Methods of Acid Mine DrainageThe County number for each mine is given in these lists, together with any alternative name that the mine has been known by Descriptions are arranged as follows: 1 The name generally used by the mine, 2; alternative names, 3; name of parish or parishes in which the mine occurs, 4; National Grid reference of the site, 5; short description ofThe NonFerrous Mines of Denbighshire Northern Mine 2022年5月6日 With the development of technology, the concepts of “green” and “sustainable” have gradually been popularized in all walks of life With the continuous development of the world mining industry, the efficiency of resource development in various countries has been improved, but mining activities and production will undoubtedly bring many environmental pollution The Recent Progress China Has Made in Green Mine Construction
