An overview on the characteristics and origin of iron

structure of ore There are two types of ores, including iron and copper ores (block-shaped, stratiform-like, stripped and disseminated) as well as single copper ores (copper-bearing dolomite, copper-bearing schist ore). The ore structure is mainly heteromorphic and idiomorphic grain structure, with metasomatic and variegated structure. Ore minerals

Characterization of iron ore by visible and infrared

01-01-2015· The banded iron-formation iron ores are dominated by gangue minerals such as carbonates, silicates and iron minerals consisting mainly of magnetite with a total content of around 30%. These ores need processing by such techniques as crushing, magnetic separation, and sometimes flotation to produce a magnetite concentrate of economic grade (>≈60% Fe).

[PDF] Characterization and origin of alunite in the El

Iron forms at least a part of the iron ore in the El-Gideda mine. Glauconite intercalated by alunite is highly destabilized with fractured pellets and iron rims as well as low potassium content. Therefore, alunite and halloysite can be considered as by- products of weathering of the intercalated glauconites in an environment of sulfide oxidation (i.e., high Eh, low pH together with biological

The Innovation and Adoption of Iron in the Ancient Near

21-02-2019· This review synthesizes field research, textual analysis, and archaeometric data to evaluate different explanations for the spread of iron in the ancient Near East. Current evidence supports an Anatolian origin for extractive iron metallurgy on a limited scale sometime in the early 2nd millennium BC. However, the first major expansion of iron, both in Anatolia and across the wider Near East

Characterization and Beneficiation of Iron Ore Tailings

20-10-2015· In the present paper, an attempt has been made to beneficiate iron ore tailings by selective flocculation using guar gum and starch as flocculants along with sodium hexametaphosphate (SHMP) as the dispersant. The mineralogical studies carried out initially indicated the presence of hematite and goethite as major iron bearing mineral phases along with quartz and kaolinite as major
