A large number of unexploited low-grade vanadium-titanium magnetite deposits have been found in the Chao-yang area of China in recent years. The reserves are estimated at more than 20 billion tons. A mineralogical study of raw sample indicated that it was a typical low-grade vanadium-titanium magnetite ore with weathering. Most of vanadium-titanium magnetite was replaced by martite and sphene, which

Beneficiation of a low-grade, hematite-magnetite ore in

01/05/2014  In China, most reserves of rich iron ores have now been depleted and sustainable development of low-grade iron ores has become a critical discussion topic in the mining industry today. The aim of this study was to evaluate the applicability of beneficiating a low-grade, hematite-magnetite ore (assaying 18.64% Fe) for subsequent utilization. In this study, process mineralogy and

01/11/2020  The low-grade laterite ores used in this study was obtained from Fuzhou City, Fujian Province in China, and they are a typical saprophytic laterite ore. The main chemical composition of the laterite nickel ore is 1.71 wt.% TNi, 20.37 wt.% TFe, 25.56 wt.%

Adding value to iron ore, at a cost: Australia’s magnetite ...

23/02/2021  Junior miner Atlas Iron's approach had been to quickly get its low grade (57.5% Fe) direct shipping (hematite) ore to China to generate cash flow to develop other mines. It was a very simple operation; after minimal processing the ore was trucked the short distance to Fortescue Metals Group's rail facility, loaded and taken to Port Hedland for export. Hematite DSO is what Australia's iron ore

Why iron ore grade is now more important than ever -

24/05/2020  Hematite is higher grade in the ground, while magnetite deposits are large and quite low grade – but produce very high-grade products. Grade is king. Grade doesn’t mean much to those not in the mining game, but to producers there are several reasons why it is key to the profitability of their operations. Iron ore mining is a high-volume, low-margin business that is capital eintensive and ...

Iron ore, metallurgical coal and China's steel reforms BHP

When margins are low or non-existent, productivity incentives are also low. This encourages the use of lower grade raw materials as a cost containment measure. That compresses the premiums paid for higher grade met coal and iron ore and trims the discounts faced by lower quality products. In the reverse situation - i.e. margins are high and productivity incentives are amplified - the mills ...

Hydrogen Reduction of Hematite Ore Fines to Magnetite

Surplus coke oven gases (COGs) and low grade hematite ores are abundant in Shanxi, China. Our group proposes a new process that could simultaneously enrich CH 4 from COG and produce separated magnetite from low grade hematite. In this work, low-temperature hydrogen reduction of hematite ore fines was performed in a fixed-bed reactor with a stirring apparatus, and a laboratory Davis magnetic ...

China wants more top quality iron ore - and these ASX ...

01/11/2018  This is good news for Australian iron ore players with high grade, low impurity projects. The price difference between low and high grade iron ores is getting wider. These growing premiums for high-grade iron ore products in response to China’s drive to improve the efficiency of its steel industry — and reduce air pollution — has brought Australia’s magnetite sector in from the cold.

Iron Ore - Department for Energy and Mining

The world's resources are dominated by low-grade ore, though current world production of iron ore is largely by supply from deposits of high-grade ore composed of either rocks of massive hematite or pisolitic goethite. World iron ore production in 2013 was 2.95 billion tonne, with the major producers being China, Australia, and Brazil. Production in Australia was 530 Mtonne. South Australian ...

Low grade iron ore steals spotlight in export markets

22/06/2019  After hitting a 10-month low in February 2019, iron ore imports by China have bounced back, rising to 86.42 mt in March, their latest customs data showed. Imports escalated as steel mills replenished stocks before winter output curbs ended in April. During January-March 2019, China imported 261.9 mt of iron ore, down by 3.5 per cent over the year ago period. Iron ore futures at

Magnetic Separation and Magnetic Properties of Low

22/11/2014  The relation between the magnetic separation behavior and magnetic properties of a low-grade manganese ore was analyzed before and after treatment by direct reduction with coal. It was found that raw ore with an initial average grade of 10.39% Mn and consisting of diamagnetic and paramagnetic minerals can be concentrated by high-intensity magnetic separation to produce a salable product with a grade of 22.75% Mn and a recovery of 89.88%. In contrast, direct reduction of the ore
