The successful application of this separator in the Zhangjiawa iron ore (mine in China) ... To economically exploit iron ore mining, dry magnetic pre-selection technology is essential. Given the fineness of the useful minerals embedded in particles, these particles need to be crushed or ground to throw off more qualified tailings. ...
Mining magnetic separator is a common equipment in mineral processing. And magnetic separation is the main method of iron ore dressing.
Magnetite is the most magnetic of all the naturally occurring minerals on earth and can be readily extracted by low-intensity magnetic separators from magnetite ores. On the other hand, oxidized iron ores like martite, hematite, specularite, limonite, and siderite are weakly magnetic, and require high-intensity and high gradient magnetic ...
With the increasing decline in ore quality and the increasing demand for high-quality raw materials, such magnetic separation technologies with higher separation performance are inevitably required by industry, and they include the scaling-up of current magnetic separators to meet the demand for larger-scale and lower-cost exploitation of …
