Investigating collector and depressant performance in the flotation of selected iron ores
As the excessive extraction of high grade iron ore reserves has led to the rapid depletion of these ore bodies, there is a growing need to extract and upgrade low grade iron ores into more economically viable products with an iron content in excess of 50%. The beneficiation of low grade iron ores …

Prospects for Liberian iron ores considering shifting patterns of trade in the world iron ore industry.
… examines the performance of the Liberian iron ore industry from 1950-1985 and its viability in global markets, assuming stagnation (World Bank) and expansionist (Leontief et al.) expectations. It examines past trends in trade and investment patterns in the light of equilibrium allocations …

Experiments on the manufacture of cast iron from Katahdin and Manhattan iron ores in the Institute blast furnace
Thesis (B.S.)--Massachusetts Institute of Technology, Dept. of Mining Engineering and Metallurgy, 1878.

A comparison of the different methods of determining carbon and graphite in cast irons and steels of volumetric methods for determining iron in irons steels and iron ores and notes on Meinickes process for determining sulphur and phosphorus in cast irons and steels
Thesis: B.S., Massachusetts Institute of Technology, Department of Chemistry, 1877

Iron-Cemented Drift in Logan County, North Dakota
… material to be similar to that of most bog-iron ores, and that this cement accumulated during a pre-Wisconsin interglacial age. </p><p>The glacial drift directly overlying the iron-cemented drift has previously been assigned to the Tazewell (?) sub-age; however, the writer believes it to be …

Identification of The Steel Decarbonization Options for Different Regions
Iron and steel manufacturing stands as a leading contributor to global CO2 emissions and ranks as the second-largest energy consumer within heavy industries. Over the last decade, this industry alone has accounted for over 7% of global greenhouse gas emissions. Consequently, there is an urgent …

The Technology of Ancient and Medieval Directly Reduced Phosphoric Iron.
… most commonly detected element in archaeological iron. The typical phosphoric iron range is 0.1wt% to 1wt%P. The predominant source of phosphorus in iron is the ore smelted. Around 60% of economic UK rock iron ore formations contain over 0.2%P. Under fully reducing conditions, both in liquid-state …

Dielectric Properties of Minerals and Ores and the Application of Microwaves for Assisted Comminution and Ore Sorting
… on key sulphide and silicate minerals and select ores at various frequencies and temperatures using the cavity perturbation technique. In combination with data from the literature, experimental data were used to ascertain which minerals could be defined as highly microwave-amenable phases (HMAPs). …

Geochemical Analysis of Ironstone Preserved Molluscan Fossils of the Hell Creek Formation (Cretaceous) and Ludlow Member of the Fort Union Formation (Paleogene) of Southwestern North Dakota
… Montana and western North Dakota produce ironstone preserved freshwater molluscan fossils. Ironstone preserved mollusks are associated with ironstone nodules, which have been described as composed of iron carbonate, iron oxide, or manganese oxide by various researchers. To date, the exact …

Ironworking in late medieval Ireland, c. AD. 1200 to 1600
… None of these could have taken place without iron. Axes were needed for clearing woodland, ploughs for turning the soil, saws for wooden buildings and hammers and chisels for the stone ones, all of which could not realistically have been made from any other material. The many battles, waged …

The simulation of material types in a Western Australian iron deposit
Geostatistical methods are currently used by mining companies to determine a resource model of the tonnage and head grade that may be obtained from a potential orebody, making it one of the first and most vital operational stages in any mining project. Currently long term mine planning is based on …
