China vows greater iron ore self-sufficiency as ‘deglobalisation tide
China will encourage domestic exploration of iron ore and use more scrap metals to reduce reliance on imports from countries like Australia, while streamlining production quotas for The degree of reduction for pellet with C/O ratio of 08 is lower than pellets with C/O ratio of 10 and 12 after reduction for 900 s. The degree of reduction is 9584%, which is high enough in engineering, when furnace temperature, reduction time, C/O mole ratio, and pellet diameter are 1473 K, 10 min, 12, and 20 mm, respectively.Numerical simulation and parameters optimisation of direct reduction

Sluggish iron ore supply response could hamper China's decarbonization
Stronger Chinese domestic iron ore production is also expected as high prices keep more high-cost supply in play, with 252 Mt of 62% Fe content equivalent output forecast for 2021. Indian iron ore exports to China — most of which are low-grade, below 58% Fe content — over recent years have helped fill shortages in the seaborne market.Keywords Direct reduction Magnetic separation Low-grade iron ore Iron recovery Introduction Effective utilization of low-grade iron ore is essential in order to reduce production cost and solve the problem of gradual depletion of high-grade iron ore. There are abundant resources of low-grade iron ore in China; nevertheless, it commonly hasHighly Efficient Iron Recovery from Low-Grade Refractory Iron Ores

Mineralogical and Chemical Changes after Reduction Roasting of
The mineralogical and chemical changes in Chinese Xinjiang iron ore containing impurities, lead, and zinc as a result of reduction roasting were studied via chemical analysis, optical microscopy, X-ray fluorescence (XRF), electron probe microanalysis (EPMA), and energy-dispersive spectroscopy (EDS). Analysis showed that The direct reduction process involves the removal, or reduction, of oxygen from typically pelletized iron ore in its solid state, therefore without melting. Natural gas is the main fossil fuel used to produce the reducing syngas gas, composed of hydrogen and carbon monoxide, although coal can also be used, albeit with much higher emissions.Regional uptake of direct reduction iron production using

The Direct Reduction of Iron Ore with Hydrogen MDPI
The steel industry represents about 7% of the world’s anthropogenic CO2 emissions due to the high use of fossil fuels. The CO2-lean direct reduction of iron ore with hydrogen is considered to offer a high potential to reduce CO2 emissions, and this direct reduction of Fe2O3 powder is investigated in this research. The H2 reduction conducted pot grate sintering experiments on iron ores with different particle sizes (mean particle size of 1.22 to 3.95 mm). The sintering productivity increased with the increase in the mean particle size of iron ore due to the increase in the flame front speed (FFS) and the increase in the bed permeability at a lower sintering time.Research on the Quality Improvement and Consumption Reduction of Iron

Direct reduction of iron ore pellets by H2-CO mixture: An in-situ
The iron and steel metallurgy industry faces the question of how to replace carbon in iron ore reduction to reduce CO 2 emission in basic industries and achieve the expectation of "double carbon". This study investigates the reduction swelling of individual iron ore pellet under mixed H 2-CO atmospheres and at temperatures of 800–1000 ℃ In order to increase agglomeration production and improve its quality while reducing energy consumption, a new intelligent blending method has been established at Ansteel to optimize its sinter blends. The statistical model of the ore blending results shows that (1) a blending ratio of 47.2% Ore A and 52.8% Ore C corresponded to the best Research on the Quality Improvement and Consumption Reduction of Iron
