World Production and ResourcesTypes of Iron OreSouth Australian Iron OreWorld resources of crude iron ore are estimated to exceed 800 billion tonnes containing more than 230 billion tonnes of iron. 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 Au
Separation of manganese and iron for low-grade
A creative method of using siderite (FeCO 3) as a novel reductant for clean utilization of low-grade refractory iron ore by magnetization roasting and low-intensity magnetic separation technology was proposed. To verify the applicability of this route, typical refractory iron ore from Jiuquan Iron and Steel Co., Ltd, China was investigated.

Hydrogen Reduction of Hematite Ore Fines to Magnetite
AbstractIntroductionMaterials and MethodsResults and DiscussionsConclusionsAcknowledgmentsSurplus coke oven gases (COGs) and low grade hematite ores are abundant in Shanxi, China. Our group proposes a new process that could simultaneously enrich CH4 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 tube was used for the magnetic separation of the resulting magnetit
Removal of Silica and Alumina as Impurities from Low
This study investigates the removal of silica and alumina as impurities from hematite based low-grade iron ore containing 34.18 mass% iron, 31.10 mass% of silica and 7.65 mass% alumina. Wet high-intensity magnetic separation (WHIMS) and reverse flotation (RF) were investigated. In WHIMS process, 93.08% of iron was recovered with a grade of 53.22 mass% at an optimum

Magnetic separation studies for a low grade siliceous iron
Abstract. Investigations were carried out, on a low grade siliceous iron ore sample by magnetic separation, to establish its amenability for physical beneficiation. Mineralogical studies revealed that the sample consists of magnetite, hematite and goethite as major opaque oxide minerals where as silicates as well as carbonates form the gangue
