2020年8月27日 tragedies have motivated research into the dry processing of iron ores. In the mineral processing industry, dry magnetic separation is commonly used for removing tramp metals [10] and the coarse cobbing of magnetite ores [11,12]. However, it is ine cient for processing finely ground magnetite ores [7,10]. This is because conventional dry ...
