copper-gold-tin-iron / ore deposits type / mineral resource potential / Bolivia 玻利维亚是世界最著名的矿产储藏国之一,据Bertrand等[1]统计,玻利维亚已发现884个矿床,依据矿床规模,大型矿床有21个,中型矿床有105个。Arce Burgoa[2]进一步对玻利维亚主要金属矿床进行了分类,识别出14种成矿类型(图1),其中...
(3) Manganese Wad: Monoclinic system, crystals are columnar with longitudinal striations. Often found in crystal clusters in the druses of some manganese-bearing hydrothermal veins, in sedimentary manganese deposits mostly as cryptocrystalline lumps, or in oolitic, botryoidal aggregates, etc. Mineral...

However, when large enough deposits are found, there are several ways the ore can be mined, depending on the type of ore and the location, including pit mining, strip mining or dredging. Iron mines look pink because iron turns pinkish or reddish when it oxidizes. Once ore is mined, it...
