The presence of slimes may be harmful to the flotation process, affecting the selectivity and the quality of the concentrates, besides causing an increase in reagents consumption. This work describes the behavior of nine iron ore types from the deposits of Fabrica Nova e Alegria with respect to ...
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...

The Southeast Missouri (USA) iron metallogenic province within the Mesoproterozoic St. Francois Mountains terrane includes eight major iron deposits and approximately 30 minor deposits. Three of the major deposits have been mined: Pilot Knob magnetite, Iron Mountain, and Pea Ridge. These deposits have...
Phosphorus in different types of ore, sulfides in the iron deposits, and the type and origin of ores at Kiruna In the Kiruna-type iron ores, apatite has been regarded as the most conspicuous mineral. Advocates of the magmatic-intrusive mode of ore emplacement at Kiruna have argued that the ...
