Mineral dressing (= Orebeneficiation)
Therefore, the first part in any ore dressing process will involve the crushing and grinding (which is also known by a common name called "comminution") of the ore to a point where each mineral grain is practically free. Crushing. Comminution • Crushing and grinding are usually carried out in a sequence of operations by which the lump size is reduced step by step. There are 3 stages of ...

Pelletizing Process
iron ore. His process involved grinding taconite to remove gangues and upgrading the iron ore (, an ore beneficiation process). The resultant highgrade ore is in the form of fine particles, as small as or less, which are not suitable for sintering. This issue led to the use of pelletizing. Pelletizing plants are expected to play an important role in an era when the global reserve of ...
