This chapter introduces the principle of how low-grade iron ores are upgraded to high-quality iron ore concentrates by magnetic separation. Magnetite is the most magnetic of all the naturally occurring minerals on earth, so low-intensity magnetic separators are used to upgrade magnetite ores.
Our two-stage magnetic separator therefore combines a STEINERT MTP extracting magnetic drum with a STEINERT MSB traversing magnetic pulley. Whilst the former generates valuable scrap iron, the magnetic pulley in the second stage separates weakly magnetic components that represent impurities in downstream processes and can have …

The problem is to utilize millions of tons, and we may safely say billions of tons, of now worthless iron-bearing rock and to produce from it 10,000,000 to 20,000,000 tons per year of high-grade ore carrying 60 per cent, iron or higher; to take the lean material as found in nature, varying widely in iron content, and bring it up to a uniform ...
1. Introduction. Low-grade iron ores are being increasingly exploited to meet the increasing consumption for iron concentrates in the iron and steel industry of China (Dwari et al., 2013, Xiong et al., 2015).But, a complicated flowsheet combining fine-grinding, classification and multi-stage separations is inevitably required for the production of …
The commonly used magnetic separation equipment includes wet high-gradient magnetic separators and dry high-gradient magnetic separators [20]. Ran and Zhang [21] utilized a two-stage dry high ...
Magnetic Separators and the Recovery of Ferrosilicon in Dense Medium Recovery Circuits 3 Ferrosilicon losses can be the second largest component of the operating costs of a heavy medium separation plant. Consequently a high priority has been placed on the design and operation of medium recovery circuits to reduce losses.
ROM ore is crushed in three stages to 90 mm nominal top size before rigorous washing and separation into five size fractions. The two coarsest fractions, −90 + 25 mm and −25 + 8 mm are gravity fed to the DMD plant with two separate Wemco drum sections (Fig. 10.1) while the two middle fractions −8 + 5 mm and −5 + 2 mm are fed to …
