The first step of physical beneficiation is crushing and grinding the iron ore to its liberation size, the maximum size where individual particles of gangue are separated from the iron minerals. A flow sheet of a typical iron ore crushing and grinding circuit is shown in Figure 1.2.2 . This type of flow sheet is usually followed when the crude ore contains below 30% iron.
a crushing circuit including high pressure grinding rolls at Argyle Diamond Mine. Recent feasibility studies for the Boddington Expansion Project have considered the use of HPGR for hard rock multi stage crushing and ball mill circuits at high tonnage rates .

From this circuit, complexity increases to multi stage crushing circuits preparing feed for multi stage grinding circuits. Fig. 2 showing a three stage rod mill ball mill arrangement is an example of a complex grinding circuit. Stage concentration further complicates the flow.
