The sulphide ore undergoes initial crushing in a C-100 primary jaw crusher, with the crushed product conveyed to a ball mill. The output is then directed to a of cyclones for size classification. The cyclone underflow is recycled to the ball mills for further grinding, forming a closed loop within the grinding circuit.
