Generally, the ore and the gangue are mined together—i.e., taken out of the host rock in a mass by either mechanical or manual means. Then the ore is separated from the gangue by various operations known collectively as mineral processing, or ore dressing. The desired metallic element is then extracted from the ore by various smelting ...

Originally, the pelletizing process was developed in the United States to treat the ultrafine mineral dressing products obtained from the upgrading of Mesabi ore. In fact, depletion of higher-grade iron ore reserves in North America promoted the development of low-grade "taconite" ores, which require very fine grinding for beneficiation.

The mineral dressing process refers to the process of continuous processing of ore. The mineral dressing is a constant production process consisting of ongoing operations. Mineral raw materials enter the sorting operation after crushing to separate valuable minerals from gangue or various beneficial minerals from each other.
