The Croft Mine is an underground mine that operated from 1914 – 1934, producing 1,770,669 tons of iron ore. This historic site now offers a museum, simulated mine shaft, and authentic mining artifacts. The old concrete cap with the steel buckets on top is the original Croft Mine shaft.
The utilization of coke oven gas for production of direct reduced iron (DRI) in the integrated steelmaking route is still under evaluation and discussion. In this study, iron ore pellets were isothermally reduced with simulated original and reformed coke oven gas (RCOG) at 700–980°C.
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".

Located in the remote Pilbara region of northwestern Australia, the SINO iron ore project is the largest monomer mining project in the Australian resources field and includes the world's largest mill. The USD 10 billion project presented design, construction, and communication challenges because of the differences between Chinese and ...
Laboratory iron ore sintering studies. 1. Process simulation and airflow rate C. E. Loo*1 and R. D. Dukino2 Iron ore sintering is the most popular process used to produce a suitable feed for the blast furnace. With changing iron ore supplies and composition, steel mills have to continually adjust the blended ore mix composition to the sinter plant.
iron ore sizes in order to investigate its effect on sinter yield and productivity. 2. Mathematical Model Some reasonable assumptions and simplifications were adopted before modeling the iron ore sintering process. ... The iron ore sintering process was simulated and compu-
The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items. It is the most-used metal by both tonnage and purpose.
Considering these binary destinations ORE/WASTE, at the mining time t, and combining each realisation of the simulated random function Zcs_i (X), there are four possibilities for each SMU simulated value: 1. the block was simulated as ore and is actually ore (OO), 2. the block was simulated as ore and is actually waste (OW),
COREX (Coal-Reduction-Extreme) smelting reduction process provides a sustainable developing way for ironmaking industry, but the sources of iron ore materials restrict its development in China. Meanwhile, the application of sinter, which is marked by low manufacture cost and overcapacity in China, to COREX furnace faced proportion limitation due to its worse low temperature reduction ...
