Connections are made between the drifts at regular intervals, which creates a checkerboard pattern of rooms and pillars. The pillars are left to support the overlying rock, and the mineral is then cut from the mining face and processed. The purification process begins with crushing the ore, which is then heated to drive off unwanted gases.
