Manganese,e. They often occur together in the same mineral or in closely intergrown mineral aggregates giving a continuous series of net oxidation states. The geochemical properties of manganese are similar to those of iron, so that its segregation into economic deposits is largely a problem of separating it from iron.作者: 裂縫 時間: 2025-3-22 01:38

Lead and Zinc,t least partly syngenetic. Shale-hosted orebodies can be exceptionally large, and are perhaps the most popular exploration targets among sedimentary ores at the present time. A transitional form between these two, one that is accordingly given considerable attention, is syngenetic ore in carbonate rocks, such as at Tynagh, in Ireland.作者: 墊子 時間: 2025-3-22 16:11 作者: 墊子 時間: 2025-3-22 18:00 作者: Mangle 時間: 2025-3-22 21:40
Aluminum and Nickel,two elements in the crust. Deep weathering under humid tropical conditions is necessary for the formation of both ore types, and aluminum ores are widely distributed in parts of the world having such climates now, or in the Tertiary, but production of lateritic Ni is largely confined to New Caledonia, the Dominican Republic, and Cuba.作者: curriculum 時間: 2025-3-23 05:15 作者: Abnormal 時間: 2025-3-23 08:52

Copper and Silver,unt, however, comes from one district, the Central African Copperbelt.
