Adopting a solution-focused approach to deliver value. M a ny iron ore producers are facing challenging times due to price uncertainty and the need to process crude material with increasing levels of impurities.
In a previous article, I discussed the reasons behind the emerging iron ore bull market and the stocks that one could invest in to benefit from this macro trend
Hematite is the most important ore of iron and it has been used by people as a pigment for at least 40,000 years. Learn about the uses and properties of the mineral hematite.
Most elements need to be concentrated into amounts that can be economically mined from ore deposits (usually hundreds to thousands of times their crustal abundance).
Houston Iron Royalties Limited. Former creditors of LIM and SMI also received shares in Houston Iron Royalties Limited ("RoyaltyCo"), a newly-formed corporation that has the right to receive a royalty equal to 2% of the sales proceeds (FOB Port of Sept-Iles) received by LIM from sales of iron ore from LIM's Houston and SMI's Malcolm properties.
Although Norse people knew of mining and mined some iron ore in a variety of locations throughout Scandinavia, most Viking era iron was smelted from bog iron.
Steel emerged as an alternative to standard traditional iron, due to its flexibility, durability, and malleability. Production of steel was a complex and expensive undertaking before the invention of the Bessemer process.
Geology, Prospecting and Exploration for Iron Ore Deposits. Iron has been known since antiquity. Iron is ubiquitous in the lithosphere as either a major constituent or in trace amounts.
BUILDING ON FIRM FOUNDATIONS, DELIVERING A SUSTAINABLE FUTURE ENHANCING VALUE In this Annual Reporting centre we seek to demonstrate that Kumba has the appropriate strategy, and the capacity to deliver on this strategy, that focuses on optimising value for all our stakeholders.

The Western Australian government announced Thursday that it has rejected Mineral Resources' (ASX:MIN) proposal to exploit the Jackson 5 and Bungalbin East iron ore deposits, located at the Helena-Aurora Range. In a media statement, Environment Minister Stephen Dawson reiterated some of the words ...
The Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities.
What are the Raw Materials needed for Refining Iron? The raw materials used to produce Pig iron in a blast furnace are iron ore, Coke, Sinter and lime stone. Iron ores are mainly iron oxides and include magnetite, siderite, limonite and hematite.
During the early twentieth century, the population of the Iron Range was among the most ethnically diverse in Minnesota. Tens of thousands of immigrants arrived from Finland, Austria-Hungary, Italy, Sweden, Norway, Canada, England, and over thirty other places of origin.

Australia is one of the world's key iron ore producers. Of the nation's natural resources, in Australia iron ore is the most plentiful. Iron ores are rocks and minerals from which metallic iron can be economically extracted.
Australia's iron ore reserves and resources are in both hematite and magnetite ores. Because of the high average grades (% Fe) of hematite ores when compared to the average grades for magnetite ores, it is necessary to report national resources in terms of contained iron.
Iron made from bog ore will often contain residual silicates, which can form a glassy coating that imparts some resistance to rusting.
While there is no doubt that conglomerate gold has been discovered in the Pilbara, the broader understanding of this style of gold mineralisation in the Pilbara remains incomplete and, therefore, any comparisons with the Witwatersrand (Wits) basin are premature, states SRK Consulting geologist Mike Cunningham.
