The iron ore market is recovering after nearly a year of supply and demand disruptions caused by Covid-19. A new normal is beginning to emerge. Governments are rolling out green-tinged recovery plans, and coke and metallurgical coal prices are still high – two factors that drive demand for higher grades. Will these factors widen the gap ...
Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine …
By 1970, combined iron ore exports from the Pilbara region had risen to 36 Mt/a, which was a major achievement at the time given the technologies and resources available and, by 1990, reached around 105 Mt/a of direct shipping ore (DSO) primarily from the high-grade Brockman iron formation.

More than ninety per cent of Australia's current iron ore exports are mined from the deep red weathered Pilbara landscape in Western Australia - and over 70 per cent of this material is shipped to China, where it is made into iron in blast furnaces using coke manufactured from coal, then further processed into steel.. Australia mines almost half …

Elevation grade (or slope) is the steepness, or degree of inclination, of a certain area of land.It can simply be the steepness between two specific points in a given area, the average of an area's gradual change in steepness, or an erratic variation in the elevation of the ground. We usually measure the ground's elevation as its altitude above …
This study presents a fluidization roasting technology for siderite-bearing iron ore without the use of carbon additives. Samples of Jingtieshan iron ore were subjected to fluidization magnetization roasting, and the effects of roasting temperature, time, and N2 flow rate on the magnetic separation performance were explored.

Iron foundries cast 3 major types of iron: gray iron, ductile iron, and malleable iron. Cast iron is an iron-carbon-silicon alloy, containing from 2 to 4 percent carbon and 0.25 to 3.00 percent silicon, along with varying percentages of manganese, sulfur, and phosphorus. Alloying elements such as
A pick up in demand for low-grade fines was observed towards the end of December, mainly skewed toward FBF. Despite so, the spread between Platts 62% Fe and 58% Fe iron ore indexes widened to its highest at $19.20/dmt since June 2022, likely attributed to the stronger uptick in medium grade fines, S&P Global data showed.
