Edison and Ore Refining Engineering and Technology

Edison planned to process 1200 tons of iron ore every twenty hours. The plant had three magnetic separators that could produce a total of 530 tons of refined ore. There was other equipment to re-refine what was left over to extract even more ore. But technical problems persisted. Iron ore rock crushers used in Edison's iron ore refiningThe average processing results are: the feed of the SLon-2500 magnetic separator is 27.5 per cent Fe, iron concentrate grade 52.40 per cent Fe, iron recovery 35.14, the fi nal tails grade 21.87Physical separation of iron ore: magnetic separation

9.5.2 Utilization of subeconomic iron ores. As magnetic separators progress toward larger capacity, higher efficiency, and lower operating costs, some subeconomic iron ores have been utilized in recent years. For example, magnetite iron ore containing only about 4% Fe (beach sands or ancient beach sands) to 15% Fe (iron ore formations) andmine the magnetic separator speciﬁcation experimentally. This method was used in this study as well. The required mix was obtained as follows. The processed ore of 10 mm size with 52 percent average iron grade was crushed and ground to ( 0.1) mm size. The required quantity of 60 percent iron concentrate was produced by a multi-stage Beneficiation of Magnetically Separated Iron-Containing

Magnetic separation studies for a low grade siliceous iron ore sample

The investigations carried out on the low grade iron ore sample reveal the following conclusions. (1) The sample on average contains 43.8% Fe, 16.8% SiO 2 and 5.61% Al 2 O 3. (2) The mineralogical studies indicate that the major iron minerals are magnetite, hematite and goethite. And the gangue minerals are silicates and calcites.Conventional magnetic separation devices are widely used for the removal of tramp iron from a variety of feed materials and for the beneficiation of ferrous ores. These devices for separation of strongly magnetic materials employ a variety of mechanical designs.

Developing high gradient magnetic separators for greener

The magnetic separator is a crucial apparatus used in the magnetic separation process [13]. With the development and consumption of resources, the position of weak magnetic mineral resources (red iron ore, manganese ore, black crane ore and tantalum-silver rare earth ore, etc.) in the national economy is becoming more prominent as resourcesThis chapter introduces the principle of how low-grade iron ores are upgraded to high-quality iron ore concentrates by magnetic separation.
