Collections: Iron, How Did They Make It? Part I, Mining

2020-9-18  As for the ratio of iron-ore to finished iron, as far as we can tell, ancient iron-working was a lot less efficient than modern iron-working. From raw ore to finished goods, the estimates range from 8-16% of the mass of the ore ends up in the finished product. Not quite enough to explain the discrepancy, but still a big gap from modern figures.

Emerging Technologies for Iron and Steelmaking

The thick slag layer separates the iron-carbon melt and char from the oxidizing post-combustion products, providing a medium for heat transfer. The exiting gas is then used to preheat and pre-reduce the iron ore feed materials. The DIOS process uses a series of fluidized bed reactors for preheating and pre-reduction of iron ore

2021 Dry Bulk Outlook Will Iron Ore Exports Be Able

2020-10-30  The Brumadinho dam disaster was a negative shock for the dry bulk market as the long-distance iron ore export out of Brazil contracted about 13%* year on year (yoy) in 2019.. The Brazilian iron ore export has a seasonality where exports tends to start off at low pace in Q1 due to adverse weather before increasing through the year, a pattern that coincides with the seasonality in the

Our underground mines LKAB

In order to mine iron ore underground, we have to build transport routes in the rock, i.e. tunnels known as drifts. Development consequently entails making preparations for mining. A development drift is blasted directly through the ore body and, if necessary, the walls and roof are reinforced with bolts, mesh and sprayed concrete.

Trade and trade-offs: Shipping in changing climates

2019-8-1  Iron ore trade has significant variation across the range of scenarios. Beside the underlying demand for steel there are two main drivers. The first is the underlying assumption on the share of steel recycled in electric arc furnaces, demonstrating a linkage between decarbonisation and trade of non-energy commodities (i.e. iron ore).
