In the processes of ore drawing and ore dressing, both the head grade and dressing grade have direct impacts on the economic benefit, resource utilization and output of concentrate of metal mines; therefore, the two grades are key parameters within the overall mining and ore-dressing processes. We assigned the given resource utilization rate and the expected output of concentrate as the two

The mining and mineral processing costs are usually high. The supply of domestic iron ores of China has been in serious shortage for a long time. Therefore, the development and utilization of complex and refractory iron ore resources are extremely urgent. Magnetizing roasting followed by magnetic separation is an important method for the beneficiation of low grade iron ores. More attention has

Previously selective mining practices were followed. But after the development of inexpensive ore beneficiation methods, bulk mining practices have proved to be more economical compared to careful selective mining. In a general way the scope of mineral dressing or ore beneficiation is twofold: 1. It helps in eliminating unwanted chemical

Regions in which iron ore has formed over millions of years (e.g. through volcanism) and can be mined economically are also referred to as iron ore deposits. Especially many ore deposits can be found in countries such as China, Australia, Brazil, India and Russia. These countries account for around 85 % of the total global iron ore mining volume.

In this machine the raw ore, after calcination was fed onto a moving belt which passed underneath two pairs of electromagnets under which further belts ran at right angles to the feed belt. The first pair of electromagnets was weakly magnetised and served to draw off any iron ore present. The second pair were strongly magnetised and attracted the wolframite, which is weakly magnetic.
